Worm gearbox,worm gear uses

JA worm gearbox cylindrical gear vertical output is designed and produced according to national professional standard JBJ19004\GB9147\JB/T2982 for automatic welding equipment: combination of worm gearbox and cylindrical gear reducer, cycloidal pin and cylindrical gear reducer, Special reducer for integrated roller frame combined with cycloidal pinwheel and worm gearbox reducer. It is suitable for self-adjusting double-drive roller frame, mobile welding roller frame and other automatic welding roller frame drive.

Scope of application:

  1. The high speed shaft rotation is not more than 1500 rpm.
  2. 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. The reducer can be used for both positive and negative directions.


Theworm gear usesare made of high-quality carbon steel and use advanced processing technology. Theworm gear useshave high precision and good contact. The worm wheel is made of ZA19-4 aluminum bronze and the worm is made of 40Cr hardened grinding teeth, thus ensuring the wear resistance of the worm gearbox pair. ,long lasting.

  1. The gear transmission efficiency is greater than 90%, the worm gearboxtransmission efficiency is greater than 65%, and the cycloidal pin gear transmission efficiency is greater than 90%.

2, smooth operation, low noise

3, small size, light weight, long service life, high carrying capacity,

4, easy to dismantle and easy to install.

Model, specification and representation:

Specifications are: JA2, JA3, JA3, JA4, JA5

display method:


Description: JA2- reducer model, 1593-speed ratio of the reducer, 2.2KW-input motor 2.2KW, four-stage

Lubrication of the reducer:

  1. Lubrication and cooling of the reducer are oil pool lubrication and natural cooling.

Lubricating oil is selected from intermediate gear oil N320 (or VG320, Mo-bi1632)

2, bearing lubrication

With splash lubrication, the bearing lubricants are the same as the gear lubricants.
