Worm gear reducer use, maintenance precautions and worm gear repair
Hits:471         Date:2020-07-25
The worm gear reducer is the key equipment of the vertical mill system. Because the mission of the worm gear reducer is particularly bad, it must run under continuous shock, vibration, and overload conditions, and the service life requires more than 15 years and the reliability requirements are particularly Therefore, the use of vertical mills puts forward higher requirements on the design and manufacture of worm gear reducers.
When using a worm gear reducer, the maximum temperature of the lubricating oil should be less than 85°C. If the oil temperature rises abnormally, and abnormal noise is generated, it should be shut down immediately for inspection, and the fault can be removed before continuing to use.
In the maintenance and inspection of the worm gear reducer, there will be more items to be inspected, but in the actual inspection, the maintenance personnel cannot maintain it well. Basic routine items must be detected in place, which is an effective guarantee to ensure the efficient operation of the worm gear reducer.
During the repair process, the parts are always at room temperature, no internal stress, no thermal deformation, cracks, annealing, softening, and no potential effects of breakage or cracking. High bonding strength, no shedding, no hard spots, high surface finish, and adjustable hardness. Suitable for low carbon steel and low carbon alloy steel, medium carbon steel and medium carbon alloy steel, high carbon steel and high carbon alloy steel, high strength alloy steel, stainless steel, cast steel, cast iron, copper and copper alloy, aluminum and aluminum alloy , Zinc and zinc alloy, chromium, nickel, chromium-nickel steel and unknown materials for repair. The repair position is accurate and flexible, and the repair volume can be controlled with precision. It can also be repaired on-site without disintegration. After the repaired position of the refined bevel gear, the tooling grinding technology can be used to accurately restore the size. The reducer is used to grind cement, coal and other industrial materials such as construction, chemical industry, ceramics, etc. It has a series of advantages such as small size, light weight, small area, low power consumption, energy saving agreement reached more than 30%, and long service life.
The general items are as follows:
1. Check the wear of the worm gear and worm, and repair or replace it.
2. Check whether each bearing is worn or damaged, measure the clearance, adjust or repair it, and replace it if necessary.
3. Check whether the sealing of each joint surface, shaft cover, shaft end, etc. is good. Deal with the oil leakage or replace the gasket.
4. Check the case for cracks or damage, and make necessary repairs.
5. Check whether the oil level gauge is complete and in good condition, and refuel or change the oil after maintenance.
In addition to the above inspection items, the following three points should be noted during the maintenance process:
1. Do not hammer the worm gear reducer housing by gravity to avoid damage.
2. The user should strictly follow the established maintenance system, and carefully record the use status of the worm gear reducer and the problems found in the maintenance. Data and text are the references for solving problems for a company and a department.
3. The replacement of new spare parts must be used after running-in and load test. (When replacing parts of worm gear reducer, it is recommended to contact our company to purchase original parts. Original accessories such as gears will better meet the design parameters of the worm gear reducer.)
