Type: reducer, reducer suitable machinery: scraper conveyor Model: JS30 Brand: Luoyang vision???? JS30 type reducer (reducer) for SGB420/30 type scraper conveyor. ??? SGB420/30 type scraper conveyor using JS-30-type gearbox, the gear reducer is three, involute gear. Total transmission is 22.24. The first level, arc bevel gears, helical gears for the second level, third level for spur gears. All levels of the technical parameters of the gear in Table 1. Total progression Teeth modulus helix angle gear transmission ratio than the overall transmission ratio at all levels of the first stage 14.33 ms = 6 35 ° 2.357 22.24 Level 15.52 mu = 5 10 ° 3.466 III 18.49 m = 6? 2.722??? ? The reducer in the structure than the general mining cone, cylinder gear reducer has greatly improved, using a set of the first axis double row spherical roller bearings and two sets of single row radial ball bearings. Arc bevel gear rotates the axial force generated by the two sets of single row radial ball order to bear. Double row radial ball roller bearings lubricated by splash. Two single row angular contact ball bearings on the 2nd sodium base grease lubrication. Arc bevel gear shaft axial and axial clearance are set by adjusting the single row radial thrust bearing pads to ensure that both ends of the adjustment. SGB620/40 What does it mean ah? ?
