A combined self-radiating and self-lubricating linear bearing

Abstract

The invention provides a combined self-cooling self-lubricating linear bearing. The linear bearing is characterized in that a plurality of ball rotating assembly mounting grooves are uniformly distributed in the axial direction of the inner surface of a bearing sleeve, each ball rotating assembly mounting groove is provided with a set of ball rotating assembly, the two ends of an inner ring of thebearing sleeve are provided with connecting threads, and end cover ventilation assemblies are arranged at the two ends of the bearing sleeve and are connected with the connecting threads. The combined linear bearing can be combined, the heat generated in the bearing can be dissipated through the ends, the number of the ball rotating assemblies can be properly increased and reduced, balls and retainers with different specifications can be replaced to meet the requirements of different diameter guide shafts, the application range of the linear bearing is enlarged, the problems that the linear bearing is inconvenient in ball lubrication and ball replacement are solved, meanwhile, the rate of temperature change inside the reaction bearing can be monitored at any time, the temperature rise characteristic in the bearing can be known, and a working condition basis is provided for bearing correlation performance analysis.

Description

technical field [0001] The invention belongs to the field of bearings and relates to a combined self-radiating and self-lubricating linear bearing. Background technique [0002] Linear bearings are commonly used parts in mechanical equipment that can achieve linear motion. Traditional linear bearings usually include four parts: balls, ball cages, bearing sleeves, and sealing rings. In the existing linear bearing, when a certain ball rotating assembly is damaged, all the ball rotating assemblies need to be replaced, which increases the replacement cost. The current linear bearings on the market can basically meet the basic functions of linear bearings, but there are many shortcomings. The balls of linear bearings are prone to wear and damage during use, but the traditional linear bearings are not enough in terms of ball lubrication and ball replacement convenience. In this case, a large amount of heat will be generated, which will affect the performance of linear bearings. ...

AI Technical Summary

Problems solved by technology

The balls of linear bearings are prone to wear and damage during use, but the traditional linear bearings are not enough in terms of ball lubrication and ball replacement convenience. In this case, a large amount of heat will be generated, which will affect the performance of linear bearings. At present, the focus of linear bearings on the market is basically on the cooling of linear bearings, and the monitoring of internal temperature of linear bearings and real-time feedback have not been done. not enough

In addition, for the sealing effect of existing linear bearings, the end cover of the bearing is usually made into a complete sealing effect, which is not necessary under better environmental and working conditions.

The complete sealing of the end cover hinders the heat dissipation inside the bearing, which is not conducive to the reduction of the internal temperature of the bearing
