In order to extend the service life of the bearing; pay attention to the protection and maintenance of industrial bearings, to prevent accidents; to ensure the reliability of work; to improve the productivity, economics, to protect the working specifications of the most appropriate mechanical working conditions; The content includes supervision of working conditions, compensation or replacement of smoothing agents, and timely disassembly. As an overhaul in the work; there are bearing rotation, oscillation, temperature, smoothing condition, etc. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Removal of the bearing: When disassembling the lower bearing for inspection; firstly record the appearance of the bearing; recognize the residual amount of the smoothing agent; after sampling to see the smoothing agent; wash the bearing. As a scavenger; usually use gasoline, fire oil. The removal of the bearing; the coarse removal and the fine removal; the separation is placed in the container; the metal mesh bottom is placed first; the bearing is not directly touched the dirt of the container. When the coarse removal; if the bearing is rotated with dirt; Will damage the rolling surface of the bearing; should pay attention to. In the coarse oil removal; use the brush to remove the smooth grease, adhesive; after the clean; turn into the fine wash. Fine wash; is to rotate the bearing while cleaning the oil; Careful removal. Others; always remove the oil and keep it clean.
2. Inspection and discriminating of the bearing: In order to judge whether the disassembled bearing can be used; to check after the bearing is cleaned. Check the condition of the raceway surface, the rolling surface, the cooperation surface, the wear condition of the bracket, and the bearing clearance. Addition and damage with irrelevant scale accuracy; abnormal. Non-detached small ball bearings; use one hand to support the inner ring horizontal; rotating outer ring to admit whether it can flow. Tapered roller bearings and other separate bearings; The rolling surface of the rolling body and the outer ring are not viewed. The large bearing cannot be rotated by hand; pay attention to the appearance of the rolling body, the raceway surface, the holding frame, the rib surface, etc. The higher the importance of the bearing, the more stable it is necessary to view.
3, the intention of the smooth bearing: the smooth intention of the rolling bearing is to reduce the internal conflict and wear of the bearing; avoid burning, its smooth effect is as follows. Import pump valve. 1), reduce conflict and wear. In the ferrule that constitutes the bearing The rolling body and the adherent touch each other; avoid metal touch; reduce conflict and wear.
.2), extended fatigue life. Bearing rolling fatigue life; in rotation; rolling touch surface is smooth and outstanding; then extended. Conversely; oil viscosity is low; smooth oil film thickness is not good;
.3), discharge conflict heat, cooling, circulation oil method, etc. can use oil to discharge heat caused by conflict; or heat from outside; cooling. Avoid bearing overheating; avoid aging oil itself.
.4), other: also to prevent foreign matter from invading the inside of the bearing; or to avoid the effect of rust and corrosion. Smooth method: the smooth method of the bearing; the grease is smooth and the oil is smooth. In order to make the bearing perform well, first; Choose a smooth method that suits the application conditions and uses the intention. If you only think about smoothness; the smoothness of the oil is dominant. However, the smoothness of the grease has the expertise to simplify the layout around the bearing; the smoothness of the grease and the smoothness of the oil are comparable.
4. Bearing device: Whether the bearing device is correct; affects the accuracy, life, and function. Therefore, the device for drawing and assembling part of the bearing should be fully studied. It is expected to be installed according to the operating specifications. The working specifications are usually as follows: : (1), remove bearing and bearing components, (2), view the dimensions and finishing conditions of the dry components, (3), equipment, (4), after viewing the bearing, (5), supply smoothing agent .
5, expect to be in front of the device; just open the bearing packaging. Usually smooth grease smooth; not clean; directly filled with smooth grease. Smooth oil smooth; usually do not need to remove; but; instrument or high-speed bearings; etc.; Wash the oil; remove the anti-rust agent coated on the bearing. Remove the bearing of the anti-rust agent; easy to rust; so can not be placed regardless. Further; the bearing has been sealed with smooth grease;
6, bearing device approach; due to bearing layout, cooperation, conditions vary; usually; because most of the shaft rotation; so the inner ring demand interference cooperation. Cylindrical hole bearings; multi-use presses; or more hot-packing method. Cone For the case of a hole; directly on the taper shaft; or with a sleeve device.
7. When the device is to the outer casing; usually the clearance cooperation is more; the outer ring has the interference; it is usually pressed by the press; or there is also the cold shrinking cooperation method of the cooling device. The dry ice is used as the coolant; the cold shrinking cooperation device is used. The moisture in the air will condense on the outer surface of the bearing. Therefore, the appropriate anti-rust method is required.
