Introduction of products

Compared with other models of gearboxs, the (J)ZQ Series owns the features of small measurement, huge capacity of load, high efficiency and low volume of noise. Being used in heavy industrial machines, the products are excellent in reducing output speed and amplifying output torque. In the stage of operation, the products will show the feature of reliable stability which originates from the gears with the production processing of caburization and quenching.

Use and maintenance

(1) The lubricating oil should be filled into the oil tank of the  housing which is between the two oil screws; when the 

filling is finished, the reductor could run with load upon the only condition that the stability of operating is confirmed 

after the equipment runs without load for a while.

(2) The suitable brand of the lubricating oil: 150 # industrial gear oil being used in the summer 120 # industrial gear oil 

being used in the winter; if the industry gear oil above are in lack of, both the 50# gear oil in summer and the 40# gear 

oil in winter can be used instead.

(3) The inside of the reductor should be washed once at least within the first six months after it being used and then 

the lubricating oil should be refilled.

(4) The reductor under the circumstance of normal operation should be maintained regularly. According to the 

operating conditions and concrete situations, a thorough maintenance should be implemented every 6 to 12 month.

Below come the details of the maintenance: Open the cover board of the peephole, then check the state of friction of 

every gear. The lubricating oil should be checked carefully, if the emulsification of the lubricating oil is being 

discovered,  the whole emulsion oil must be drained out and the gears should be washed by light oil, finally refill the 

housing the new oil.

If the reductor doesn’t restore to work right away, then the oil  extractor has to operate 10 minutes at least which 

assurances the lubricating film being originated on the surface of gears and bearings of the reductor.

(5) If the bearings are lubricated with the grease, the type ZL-3 should be used in the summer and the ZL-2 lithium grease should be used in the winter, the grease should be refilled every six month.
