Abstract

The invention discloses a needle roller and cylindrical roller combination bearing. The bearing comprises a bearer, the outer peripheral surface of the bearer is a cylindrical surface, the outer peripheral surface of the rear end of the bearer is provided with a cylindrical roller bearing, the position of the rear end of the bearer corresponding with the providing position of the cylindrical roller bearing is provided with a counter bore, a needle bearing assembly is arranged in the counter bore, the needle bearing assembly comprises a fixing shaft, two ends of the fixing shaft are fixed on the side wall of the counter bore, a needle bearing outer ring is sleeved on the outer peripheral surface of the middle part of the fixing shaft, a needle roller is arranged between the fixing shaft and the needle roller outer ring, and the two ends of the fixing shaft are arranged in the U-shaped locking slots on the two side walls of the counter pore at the rear end of the bearer in a side arranging manner. In the invention, the fixing shaft is arranged into the U-shaped locking slots from the rear end of the bearer in a side arranging manner and then is fixedly arranged between the two side walls of the counter pore after the needle bearing assembly is fixed on the fixing shaft during installation, so the needle roller and cylindrical roller combination bearing does not damage the needle roller and the fixing shaft in the installation and dismounting processes.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to a bearing combined with needle rollers and cylindrical rollers. Background technique [0002] Horizontal transmission and vertical lifting transmission machinery need to be equipped with combined bearings capable of rolling in both radial and axial directions. This combined bearing requires low speed and bears large radial and axial loads. The existing combined bearings are as in the Chinese patent The announcement number is CN101709743A, the announcement date is May 19, 2010, and the name is "a composite bearing". In the specification, a composite bearing is disclosed, including a support. The outer peripheral surface of the support is a cylindrical surface, and the axis of the support is The direction is the front-to-back direction, the rear end of the outer peripheral surface of the support is provided with a counterbore, and the needle bearing assembly is installed in the coun...
