1. Ensure assembly quality. You can buy or make some special tools. When disassembling and installing the parts of the reducer, try to avoid knocking with hammers and other workers; when replacing gears and worm gears, try to use original accessories and replace them in pairs;
2. Selection of lubricants and additives. The turbo reducer generally uses 220# gear oil. For the reducer with heavy load, frequent starting and poor use environment, some lubricating oil additives can be used to make the gear oil still adhere to the gear surface when the reducer stops running, forming a protective film , to prevent direct metal-to-metal contact during heavy loads, low speeds, high torques and starting. Among the additives, the sealing ring conditioner and anti-leakage agent keep the sealing ring soft and elastic, and effectively reduce the leakage of lubricating oil.
3. Selection of the installation location of the reducer. In order to only allow, try not to use vertical installation. During vertical installation, the amount of lubricating oil added is much higher than that in horizontal installation, which may easily cause the reducer to heat up and leak oil.
4. When each unit exceeds 40°C or the oil temperature exceeds 80°C, the quality of the oil decreases, or more copper powder is found in the oil and abnormal noise occurs, stop using it immediately, repair it in time, and eliminate the fault. , Replace the lubricating oil, pay attention to the amount of oil, and ensure that the reducer is properly lubricated.

Theoretical research and optimization design of transmission meshing of TI worm gear reducer
TI transmission, the full name of the involute enveloping toroidal worm reducer transmission, is composed of an involute helical cylindrical gear and an enveloping toroidal worm. Carrying out research on the transmission of TI worm reducer has important theoretical significance and practical value for the development of high-efficiency and heavy-duty worm reducer.
In this paper, the transmission of TI worm gear reducer is studied from the two aspects of meshing theory and optimization design. The main research contents are as follows:According to the principle of differential geometry and gear meshing, the meshing theory system of TI worm gear transmission under ideal conditions is established by kinematics method. Under the premise of considering the boundary conditions, the meshing performance of the primary envelope TI worm drive is deeply analyzed.

The judging conditions for the existence of the meshing boundary line are discussed, and the simulation results show that only when two meshing boundary lines appear on the tooth surface and coincide, the distribution of the instantaneous contact line on the worm gear tooth surface is in an ideal state, and the primary envelope TI worm is obtained. The ideal helix angle of the drive. The influence of the design parameters on the contact state of the worm gear tooth surface is analyzed in detail, which provides theoretical guidance for the rational selection of design parameters. The tooth surface contact of the secondary enveloping reducer transmission is analyzed. The existence conditions of the secondary contact line on the worm gear tooth surface and the influence of the helix angle on the contact line distribution on the worm gear tooth surface and the shape of the worm gear tooth surface are studied.

The research results reveal that when the helix angle is greater than the ideal helix angle of the primary envelope TI worm drive, the secondary contact line can only appear on the tooth surface of the worm gear; within the range of the helix angle allowed by machining, the larger the helix angle, the more favorable the tooth surface is. The meshing performance is improved; the primary contact surface and the secondary contact surface bounded by the meshing limit line constitute the worm gear tooth surface of the TI secondary envelope reducer. It is studied whether the contact phenomenon of the secondary envelope TI worm drive can occur after the worm gear tooth surface wears in the primary TI envelope reducer drive. Through the analysis and comparison of a series of the same design parameters of the next envelope and the second envelope TI worm drive worm gear tooth surface shape, we can know: when the helix angle is greater than the ideal helix angle of the first envelope TI worm drive, the first envelope The contact line distribution of the secondary envelope can be obtained after the meshing wear of the TI worm drive. In order to improve the bearing capacity and improve the lubrication condition, with the design parameters as the optimization variables, the multi-objective optimization design of the primary envelope TI worm gear reducer was carried out by using the improved adaptive genetic algorithm. The optimization example shows that it is feasible and effective to apply the genetic algorithm to the optimization design of the primary envelope TI worm drive, and the method is better than the traditional optimization method.

Structure and Analysis of Parts of R Series Helical Gear Reducer

What is the structure of the parts of the R series reducer:

R series reducer is mainly composed of transmission parts (gear or worm, etc.), shaft, bearing, box and accessories. Now Xiaobian briefly introduces the structure of the reducer.

The first is the combination of the gear shaft and bearing of the helical gear, and the pinion and the high-speed shaft are integrated with the gear shaft structure. And this structure is used in the box where the diameter of the gear and the diameter of the shaft are not much different. The installation law of the R97 reducer is that the large gear is assembled on the low-speed shaft, and then the flat key is used to fix it around. The parts on the reducer bearing are axially fixed by the shaft shoulder, the shaft sleeve and the bearing cover. Since the gears of the helical gear reducer have an axial component force when they mesh, both shafts must be supported by a pair of tapered roller bearings to withstand the combined effect of the radial load and the axial load of the R series reducer. The box is also an important component of the R series reducer. The box is the base of the transmission parts. Because of its sufficient strength and rigidity, the general reducer box is usually cast with gray cast iron, and the cast steel box can also be used for the heavy-duty R97 reducer under impact load. However, in order to facilitate the installation and disassembly of the shafting components, the box body is generally made into a horizontal split type along the axis line. The upper box cover and the box base of the lower box are connected as a whole by ordinary bolts.

In order to ensure the normal operation of the R series reducer, in addition to the need to pay attention to the structural design of the gear, shaft, bearing combination and box body, it is also necessary to consider the accessories for the lubricating oil pool of the helical gear reducer, drain oil, check the oil level, Design and reasonable selection of auxiliary parts such as accurate positioning of the upper and lower boxes, lifting and transportation of the reducer during disassembly and assembly. The breather is also very important for the R series helical gear reducer. When the R series reducer works, the temperature in the box increases, the gas expands, and the pressure increases.

In order to allow the heated and expanded air in the box to be discharged freely and to ensure the balance of pressure inside and outside the box, it is necessary to prevent the lubricant oil from leaking along the sub-box surface and the extension of the shaft or other gaps, usually in the R series helical gear reducer. A ventilator is installed on the top of the box. There are also bearing caps and sealing devices in the R97 reducer, which are used to fix the axial position of the shafting components and bear the axial load. The hole end of the bearing seat is sealed with a bearing cap. Bearing caps are available with recessed flanges and flanges. The most commonly used is the flanged bearing cap. Usually fixed on the box with hexagonal screws.

I believe everyone knows what the positioning pin of the R series reducer is. In order to accurately machine the bearing seat hole and ensure that the upper and lower half holes of the bearing seat always maintain the position accuracy during processing after each disassembly and assembly, it should be before finishing the bearing seat hole. Fit the positioning pins on the coupling flanges of the upper tank cover and the lower tank base. The locating pin adopts two locating conical pins which are arranged on the connecting flanges on both sides of the longitudinal direction of the box body, and are arranged asymmetrically to enhance the positioning effect. If there is a positioning pin, there is a cover screw. In order to strengthen the sealing effect, the split surface of the box is usually coated with water glass or sealant when assembling the R97 reducer. Therefore, when disassembling the R series reducer, it is often Difficult to separate due to tight glue.
