Planet rolling bearing system

Abstract

The invention discloses a planet rolling bearing system for supporting a large disc and the rotation of a large disc gear on a circular knitting machine, which is characterized by adopting two groups of conventional rolling bearings evenly distributed and arranged on the large disc as planets, wherein one group of the conventional rolling bearings support the end face of the large disc gear, while the other group supports the central hole of the large disc gear. As shown by an attached drawing of the abstract, the planet rolling bearing system comprises the large disc gear 1, the large disc 2, a horizontal bearing block 3, a rolling bearing 4, a shaft elastic damping ring 5, a hexagon socket head cap screw 6, a rolling bearing 7, a shaft damping ring 8, an O-shaped rubber sealing ring 9, an eccentric bearing block 10, a hexagon socket head cap screw 11 and a gasket 12. By comparing the planet rolling bearing system with the prior steel wire track rolling bearing and the prior frictionplate sliding bearing, the planet rolling bearing system has the following obvious advantages that: (1) the running precision of the circular knitting machine is higher; (2) the running is more flexible; (3) the service life is longer; (4) the production cost of the circular knitting machine is greatly reduced; (5) the maintenance is more convenient; and (6) the circular knitting machine which isscrapped and cannot be required due to the abrasions of mounting parts of the large disc gear and the large disc steel wire track can be repaired completely, and the circular knitting machine which is obsolete because a wear-resistant piece sliding bearing cannot be repaired due to the abrasions of a central hole of the large disc gear and a central shaft of the large disc gear can be completely repaired.

Description

technical field [0001] The utility model relates to a planetary rolling bearing system used for circular knitting machines to support the rotation of large plates and large plate gears. Background technique [0002] 1. It is known that the rolling bearing is composed of an inner ring, an outer ring, a set of steel balls, and a steel ball cage. Its use method: the inner ring of the rolling bearing and the shaft of the mechanical part are fastened to the shaft of the mechanical part with a nut through interference fit or thread design on the shaft; the outer ring of the rolling bearing and the shaft of another mechanical part The hole is designed through interference fit or a threaded hole outside the hole, and an end cover specially designed to compress the outer ring of the bearing is designed, and the outer ring of the bearing is fastened in the hole of the mechanical part with screws and the end cover. When the shaft of the mechanical part is fixed, the hole of the mechan...

AI Technical Summary

Problems solved by technology

Based on the structure and use of sliding bearings, as well as the accuracy requirements of the circular knitting machine cylinder in operation: let's analyze its existing problems: (1) It is well known that the friction resistance of sliding bearings is much greater than that of rolling bearings, so its Equipped with motors with higher power than motors using rolling bearings

And it is difficult to start this kind of circular knitting machine in winter and cold regions

At the same time, this kind of circular knitting machine is also difficult to run at high speed.
