 In order to enhance the guide wheel support device after the repair durability, we try to take advantage of this ability to complete the conversion work unit maintenance guide wheel. The main approach is: conversion guide wheel bearing and lubrication crawler excavator manufacturers, instead of sliding bearings with rolling bearings with grease instead of gear oil. 1. The conversion program (1) the appropriate choice of bearing (2) production of bearing (3) making the flange (4) to improve the structure of the guide wheel seat 2. guide wheel assembly in accordance with the above program will guide wheel parts after manufacture conduct assembly, the assembly can be seen from the guide wheel axle bearing and the guide portion forming an annular intermediate space, that space is available to store the grease. Machined axle grease on the guide of the oil passage, one end of the guide wheel installed a grease nipple, the other end of the installation of a screw plug. When greasing need to unscrew the screw plug to drain the old grease. When mounting flange, should be evenly coated with a layer of sealant on the mating surfaces of the flange and the end face of the guide wheel bearing, and then tighten the bolts. 3. Since the guide wheel balancing test assembly is based on the conversion of the old pieces, error uneven wear and the center hole of the old guide wheel when machining center can make the guide wheel assembly after deviation, resulting in loss of guide wheel operation steady, shorten bearing life. So after assembly is complete, there is a need for balancing test. Due to constraints, we take a simple test method, is about two guide rollers are fixed to the base 2 bracket, the guide wheel dangling rubber crawler excavators, and then repeatedly rotating guide wheel, according to its rotation, stop motion law to determine the center of gravity position, and then the guide wheel center to the outer edge of the surfacing again corrected. After several months of use and observation crawler excavators, steering wheel modified after running a flexible, reliable, easy to maintain small crawler excavators, modification programs have been successful. Tracked from chain "release" How to choose butter grease fittings needed each time to shop or agent can see a lot of points accumulated yellow drums, various models of different brands. So how do we choose butter really need it? When selecting grease primarily mechanical condition should be considered where relevant, work status (continuous operation, intermittent operation, with or without vibration and shock) and the working environment (humidity, temperature, air pollution levels, etc.) on several factors. When the temperature is high, such as in the summer, you should choose a small evaporation losses, relatively strong oil; when using a temperature as low as the winter, you should choose a small viscosity, relatively thick oil release. Large load, extreme pressure additives should be selected or fillers (molybdenum disulfide, graphite) grease; in contact with water or damp air environment, should be used, such as lithium, lithium complex grease good water resistance, etc. seaside or chemical media environment, the choice of a good anti-rust performance grease; dust for a long time, you should choose a more dense and hard, good sealing grease to prevent contamination; like excavator hammer with vibration roller function Fulling size of various models should be used, such as high viscosity, good damping grease, such as high viscosity lubricant cycloalkyl or mixed base complex soap thickened grease. In meeting the requirements of the situation, try to use lithium grease, complex soap grease, polyurea grease and other pleiotropic universal grease. Thus, reducing the fat varieties, but also simplifies the management of stored fat.泰安嘉 and Heavy Machinery Co., crawler excavators specifications | Kerry and Heavy (certified) | Crawler excavators provided by 泰安嘉 and Heavy Machinery Co., Ltd ..
