Description

Technical Field

[0001] The utility model relates to the technical field of billet drawing platforms, in particular to a bearing billet drawing platform. Background Art

[0002] In the wheel throwing table, the bearing is an important component. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] During the process of throwing the blanks, the raw materials or impurities of the thrown blanks may fall into the inside of the bearing. After the impurities enter the bearing, the surface wear is very likely to occur. In severe cases, a large friction noise will be emitted, the friction force will increase and heat will be generated, and the lubricant will be lost, resulting in a reduction in the life of the bearing and accelerated damage. The existing bearing protection device has a complex structure, does not clean the impurities thoroughly, and cannot clean the tiny particles of impurities. When the bearing rotates at high speed, it will seriously affect the bearing's motion accuracy, noise and life.

[0004] For this purpose, we propose a bearing casting table. Utility Model Content

[0022] The first center gear 4 is located inside the cavity 3 and meshes with the planetary gear 8; a motor 16 is fixedly mounted on the bottom end of the support base 15, and a driving gear 17 is fixedly mounted on the top end of the motor 16; the second center gear 13 is located on the upper part of the fixed base 1 and meshes with the driving gear 17; a bearing body 18 is fixedly connected to the middle part of the bottom end of the cavity 3, and the bearing body 18 includes an outer ring 19, an inner ring 20 and a ball 21, and the ball 21 is located between the outer ring 19 and the inner ring 20; the second center shaft 14 passes through the cavity 3 and is fixedly connected to the inner side of the inner ring 20.

[0023] It should be noted that the utility model is a bearing throwing table. When in use, the output shaft at the top of the motor 16 drives the drive gear 17 to rotate. Since the drive gear 17 is meshed with the second center gear 13, the second center gear 13 drives the first center shaft 12 to rotate, and at the same time drives the second center shaft 14 to drive the inner ring 20 in the bearing body 18 to rotate and the first center gear 4 to rotate.
