回转窑开式齿轮的润滑的改进（To improve the lubrication of open gear of rotary kiln.） ======================================== page first ======================================== To improve the lubrication of open gear of rotary kiln. To improve the lubrication of open gear of rotary kiln. To improve the lubrication of open gear of rotary kiln. To improve the lubrication of open gear of rotary kiln. Author: an extensive analysis, Yang Weichen One Brief introduction of rotary kiln and open gear Our company is the production line 3, a 5000t / d cement clinker production line, December 20, 2004. The fire is put into production. Specification for rotary kiln With Four point eight * 72m, speed (max) 4.04r / min main motor power 6 30kW. The main drive for single drive gear for involute spur gear, the modulus M = 40mm, the number of teeth is Z respectively. 1 = 23, Z2 = 192; B1 = 700mm tooth width B2 = 600mm; lubricating oil Pool with lubricating oil tanker. ======================================== page second ======================================== Two Selection of lubricant In December 2004, the rotary kiln has just put into operation, in accordance with the requirement of the equipment manual, filling a domestic oil pool Brand No. 320 gear oil (equivalent to the old national standard No. 3 gear oil), which found that the vibration of the bearing block of the small gear The tooth is too large, high temperature, oil film forming bad tooth surface. But a good meshing, meshing clearance, contact length and width Are in the allowed range. Communicate with equipment manufacturing units and units that equipment installed in the running period, the partial vibration value Large tooth such as high temperature should be normal to imagine; after running, the oil film will be improved. In June 2005, a Prepare inspection found, small gear tooth surface has been pitting, tooth profile top has obvious signs of sliding friction; the gear tooth surface is Pitting, burrs protruding in rolling tooth wi
