The structure of tapered roller bearings: The type of tapered roller bearing is 30,000, and the tapered roller bearing is a separate bearing. Under normal circumstances, especially in the size range of GB/T307.1-94 "Rolling bearing radial bearing tolerance", the tapered roller bearing outer ring and the inner component are 100% interchangeably usable. The angle of the outer ring and the outer race diameter have been standardized as the outer dimensions. Changes are not allowed at the time of design and manufacture. So that the outer ring of the tapered roller bearing and the inner component can be universally interchanged worldwide. Tapered roller bearings are mainly used to withstand radial and axial combined loads based on radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings are capable of withstanding axial loads in one direction and can limit axial displacement in one direction of the shaft or housing. Installation of tapered roller bearings: Adjusting the axial clearance For the axial clearance of the tapered roller bearing, the adjustment nut on the journal, the adjustment washer and the thread in the housing bore can be used, or the preload spring can be used to adjust. The size of the axial clearance is related to the arrangement of the bearing when it is installed, the distance between the bearings, and the material of the shaft and the bearing housing, which can be determined according to the working conditions. For high-load and high-speed tapered roller bearings, the influence of temperature rise on axial clearance must be considered when adjusting the clearance, and the amount of clearance reduction caused by temperature rise is estimated, that is, axial clearance It should be adjusted a little bigger. For bearings with low speed and vibration, no clearance installation or preload installation is required. The purpose is to make the roller and the raceway of the tapered roller bearing have good contact, and the load is evenly distributed to prevent the roller and the raceway from being damaged by the vibration shock. After adjustment, the size of the axial clearance is checked with a dial gauge. Concerned about surprises Label: How much do you know about the structure and installation of tapered roller bearings?
