First, single-stage cylindrical bucket elevator parts: The rotating teeth can be made into straight teeth, helical teeth and herringbone teeth. Straight
teeth are used for lower speed (ν ≤ 8m / s) lighter load; helical bucket elevator gearbox are used for higher speed
transmissions, and herringbone bucket elevator gearbox are used for heavy load transmissions. The housing is
usually made of cast iron. Single or small batch production sometimes uses welded construction.
Bearings generally use rolling bearings, and use sliding bearings for heavy loads or particularly
high speeds. Other types of bucket elevator parts are the same as this
Second, two-stage cylindrical bucket elevator parts: 1.Expandable The structure is simple, but the position of the bucket elevator gearbox relative to the bearing is asymmetrical, so
the shaft is required to have a large rigidity. The high-speed bucket elevator gearbox is arranged away from the
torque input end, so that the torsional deformation of the shaft under the action of the torque
and the bending deformation of the shaft under the bending moment can partially cancel each
other to slow the uneven distribution of the load along the tooth width. phenomenon. For
occasions where the load is relatively stable. The high speed stage is generally made of helical
teeth, and the low speed grade can be made into straight teeth.
2. Split type
The structure is complicated, but since the bucket elevator gearbox are symmetrically arranged with respect to the
bearing, the load is evenly distributed along the tooth width compared with the unfolding type,
and the bearing is uniformly loaded. The torque on the dangerous section of the intermediate
shaft is only half of the torque transmitted by the shaft. Suitable for variable load applications.
High-speed grades generally use helical teeth, and low-speed grades can use straight or
herringbone teeth.
3. Coaxial
The lateral dimension of the Bucket elevator parts is small, the depth of the two pairs of bucket elevator gearbox immersed in
the oil is about the same, but the axial dimension is large and the weight is large, and the
intermediate shaft is long and the rigidity is poor, so that the load distribution along the tooth
width is uneven. The bearing capacity of high-speed shaft is difficult to make full use of
4. Coaxial split type
Each pair of meshing bucket elevator gearbox transmits only half of the total load. The input and output shafts are
only subjected to torque. The intermediate shaft is only half of the total load, so the journal size
can be reduced compared to other bucket elevator parts that transmit the same power.

Third, single-stage bevel bucket elevator parts: The bucket elevator gearbox can be made as straight, helical or curved teeth. It can also be used in two-axis
vertical phase-shifting transmissions for transmissions with two axes perpendicular to each
other. Due to the complexity of manufacturing and installation, the cost is high, so it is only used
when the transmission arrangement needs it. Fourth,stage two-stage cone - cylindrical bucket elevator parts: Features the same as single-stage bevel bucket elevator parts, the bevel bucket elevator gearbox should be at high speed,
so that the size of the bevel bucket elevator gearbox is not too large, otherwise the processing is difficult Bucket elevator parts scope: 1. The high speed shaft rotation is not more than 1500 rpm. 2. The peripheral speed of the bucket elevator gearbox drive is not more than 20 m / s. 3. The working environment temperature is -40-45 °C. If it is lower than 0 °C, the lubricating oil
should be preheated to above 0 °C before starting. 4. The bucket elevator parts can be used in both forward and reverse directions.
The spur bucket elevator parts is a power transmission mechanism that uses a bucket elevator gearbox speed converter to
decelerate the number of revolutions of the motor to a desired number of revolutions and
obtain a device with a large torque.

bucket elevator parts is generally used for transmission equipment with low speed and high torque. The
ordinary Bucket elevator parts of the motor will also have several pairs of identical bucket elevator gearbox to achieve the
desired deceleration effect. The ratio of the number of teeth of the large and small bucket elevator gearbox is the
transmission ratio. With the continuous development of the Bucket elevator parts industry, more and more
enterprises have applied the Bucket elevator parts.

The bucket elevator parts uses the bucket elevator gearbox transmission of all stages to achieve the purpose of speed
reduction. The Bucket elevator parts is composed of bucket elevator gearbox pairs of various stages. For example, the bucket elevator gearbox can
be driven by a small bucket elevator gearbox to achieve a certain deceleration, and then a multi-stage structure is
adopted. , you can greatly reduce the speed.
In the long-term operation of the Bucket elevator parts, there are often faults such as wear and leakage. The
most important ones are: 1. The bearing chamber of the Bucket elevator parts is worn, which in turn includes the wear of the bearing
housing of the housing, the bearing chamber of the housing, and the bearing chamber of the
transmission. 2. The shaft diameter of the bucket elevator gearbox shaft of the Bucket elevator parts is worn, and the main wear parts are in
the shaft head and keyway. 3. The bearing position of the Bucket elevator parts drive shaft is worn. 4. The Bucket elevator parts joint surface leaks.

For the wear problem, the traditional solution of the enterprise is repairing after repair welding
or brush plating, but both have certain drawbacks: the thermal stress generated by the repair
welding high temperature cannot be completely eliminated, which may cause damage to the
material and cause the parts to bend or break; Brush plating is limited by the thickness of the
coating, and it is easy to peel off. The above two methods use metal to repair the metal, which
can not change the "hard to hard" coordination relationship. Under the combined action of each
force, it will still cause re-wear.
For the leakage problem, the traditional method needs to disassemble and open the Bucket elevator parts,
replace the sealing gasket or apply the sealant, which is not only time-consuming and laborious,
but also difficult to ensure the sealing effect, and leakage will occur again during operation.
The polymer material can be used to treat leakage on site. The material has excellent adhesion,
oil resistance and 350% elongation, which overcomes the impact caused by the vibration of the
Bucket elevator parts, and solves the problem of leakage of the Bucket elevator parts for the enterprise.
A bucket elevator parts is a type of transmission that increases the wear of its internal transmission as
it works longer. So what aspects should we analyze the wear of the internal bucket elevator gearbox of the bucket elevator gearbox
Bucket elevator parts? The losses in the bucket elevator gearbox unit (bucket elevator gearbox frame and Bucket elevator parts) in the bucket elevator parts include the
following three aspects: 1. Sliding friction loss between teeth. 2. Loss in bearings, plain bearings and rolling bearings. 3. Splash and agitation of lubricant loss.
The loss problem in the bucket elevator parts is related to the friction loss in the bucket elevator gearbox transmission, the
friction loss of the rolling and sliding bearings, and the consumption and viscosity of the
lubricating oil.

There are many types of bucket elevator parts. The commonly used bucket elevator gearbox and worm Bucket elevator parts can be roughly
divided into three categories according to their transmission and structural characteristics: (1) bucket elevator parts mainly include three kinds of cylindrical bucket elevator parts, bevel bucket elevator parts
and conical-cylindrical bucket elevator parts. (2) The worm Bucket elevator parts mainly includes cylindrical worm Bucket elevator parts, arc bucket elevator gearbox worm Bucket elevator parts, cone
worm Bucket elevator parts and worm-bucket elevator parts. (3) Planetary bucket elevator parts mainly include involute planetary bucket elevator parts, cycloidal pinwheel
bucket elevator parts and harmonic bucket elevator parts.

The bucket elevator parts can be divided into single-stage, two-stage, three-stage and multi-stage
bucket elevator parts according to the number of stages of the reduction bucket elevator gearbox; the mutual arrangement of
the shafts in space can be divided into two types: vertical and horizontal bucket elevator parts; The
characteristics of the motion diagram can be divided into expansion type, coaxial type and split
type speed Bucket elevator parts. The maximum bucket elevator gearbox ratio of single-stage spur bucket elevator parts is generally
8-10, which is mainly to avoid excessive size. If i>10 is required, a secondary cylindrical bucket elevator gearbox
Bucket elevator parts should be used. The secondary cylindrical bucket elevator parts is applied to the case where the sum of the center
distances of the i:8-50 and the high and low speed stages is 250-400 mm. The three-stage
cylindrical bucket elevator parts is shown for use in applications where the drive is required to be large.
Bevel bucket elevator parts and secondary conical-cylindrical bucket elevator parts In the transmission that requires the input shaft and the output shaft to be 90~ configured.
Because the large-sized bevel bucket elevator gearbox is difficult to manufacture accurately, the high-speed stage
of the conical-cylindrical bucket elevator parts always uses a bevel bucket elevator gearbox to reduce its size and improve
manufacturing precision. bucket elevator parts are characterized by high efficiency, long life and easy
maintenance, making them extremely versatile. Machine characteristics： 1. the bucket elevator gearbox is made of high-strength low-carbon alloy steel by carburizing and quenching. The
