Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to a bearing installation appurtenance that fig. 1 ~ 4 shows, including support 1 and anchorage bar 2, anchorage bar 2 wears to locate in the 1 top of support, and can 1 top of support reciprocates, 2 bottom levels of anchorage bar are equipped with levelling device 3, levelling device 3 corresponds be equipped with stop device 4 on the 1 bottom end of support, wherein, levelness when guaranteeing bearing inner race 51 assembly through levelling device 3, stop device 4 is the extrusion displacement that causes when preventing bearing outer race 52 atress unbalance, and influences the precision of assembly.

Further, in order to facilitate the assembly of the bearing, the leveling device 3 is a circular plate, the limiting device 4 is a cylinder, the circular plate can extend into the cylinder, and during the assembly, the bearing outer ring 52 is placed into the cylinder, the bearing inner ring 51 is placed on the bearing outer ring 52, and then the fastening rod 2 moves downwards, so that the bearing inner ring 51 is placed into the bearing outer ring 52.

Further, in order to limit the bearing outer ring 51, the circular table 31 is arranged at the bottom of the circular plate, the outer diameter of the circular table 31 is smaller than the inner diameter of the bearing inner ring 51, and the bearing inner ring 51 is sleeved on the outer edge of the circular table 31 during assembly, so that the bearing outer ring 51 is prevented from moving during assembly.

Further in order to improve the limiting function of the cylinder, a step blind hole 41 is arranged in the cylinder, the step blind hole 41 comprises a first step hole 401, a second step hole 402 and a shoulder 403, the bearing outer ring 52 is clamped into the second step hole 402, the outer edge of the circular plate is clamped into the first step hole 401, the shoulder 403 is lower than the bearing outer ring 52, when the assembly is completed, the bottom surface of the circular plate abuts against the top surface of the bearing outer ring 52, and the shoulder 403 is lower than the bearing outer ring 52, so that the bottom surface of the circular plate reaches the lowest position and cannot contact the shoulder 403, and the smooth assembly of the bearing is ensured.

Further in order to facilitate the vertical adjustment of the fastening piece 2, the fastening rod 2 is an adjusting screw, a threaded hole matched with the adjusting screw is formed in the top of the support 1, the adjusting screw is in threaded connection with the top of the support 1, and the bearing inner ring 51 is acted by rotating the adjusting screw to complete assembly.
