seal tc framework oil seal 126 specifications in total Modèle 3D

Description

[seal] tc framework oil seal model + technical parameters (126 specifications) can be produced according to the drawing or drawn as the selection standard 1:1. these models basically cover all the selection requirements of tc type. welcome to download! the role of the framework oil seal is to isolate the parts in the transmission parts that need to be lubricated from the output parts, so as to prevent the leakage of lubricating oil. it is usually used for the rotating shaft of the skeleton oil seal, which is a kind of rotary shaft lip seal. the skeleton is like the steel bar in the concrete component, which plays a reinforcing role and keeps the shape and tension of the oil seal. according to the framework type, it can be divided into inner framework oil seal, outer framework oil seal and inner and outer exposed framework oil seal. the framework oil seal is made of high quality nitrile rubber and steel plate, with stable quality and long service life. widely used in automobile, motorcycle crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels and other parts. 1. prevent sand, dust, water vapor from outside into the bearing; 2. limit the leakage of lubricating oil in the bearing. the requirements for oil seal are that the size (inner diameter, outer diameter and thickness) of oil seal should meet the requirements; it should have appropriate elasticity, be able to properly block the shaft and play a sealing role; it should be heat-resistant, wear-resistant, strong, medium resistant (oil or water, etc.) and have a long service life. reasonable use of oil seal, should pay attention to the following points: (1) due to the design and structure of the shaft, high speed oil seal should be used for high speed shaft, low speed oil seal should be used for low speed shaft, and low speed oil seal should not be used for high-speed shaft, otherwise, it is not suitable. (2) in the case of higher ambient temperature, polypropylene ester or silicon, fluorine and silicon fluorine rubber should be selected. try to reduce the oil temperature in the oil tank. when the temperature is too low, cold resistant rubber should be selected. (3) the oil seal with general pressure has poor bearing capacity, and the oil seal will deform when the pressure is too high. in case of excessive pressure, pressure bearing ring or reinforced pressure oil seal should be used. (4) if the eccentricity of oil seal and shaft is too large, the sealing performance will be poor, especially when the shaft speed is high. if the eccentricity is too large, the oil seal with "w" section can be used. (5) the surface finish of the shaft directly affects the service life of the oil seal, that is, if the shaft has a high finish, the service life of the oil seal will be long. (6) pay attention to the oil seal lip should have a certain amount of lubricating oil. (7) pay special attention to prevent dust from getting into oil seal. Prêt à imprimer: Non
