Double-sealed deep groove ball bearing for elevator and escalator

Abstract

The utility model provides a double-sealed deep groove ball bearing for an elevator and an escalator, relates to the technical field of bearings, and solves the problems that in order to guarantee the sealing performance of the bearing, compared with different deep groove ball bearings, a common double-sealed deep groove ball bearing is difficult to maintain and operate in subsequent maintenance, and the service life of the bearing is prolonged. The maintenance convenience of the double-side sealed deep groove ball bearing is low, and the maintenance operation cannot be well and conveniently carried out. According to the double-sealed deep groove ball bearing for the elevator and the escalator, through the arrangement of the sealing ring, when the bearing is maintained subsequently, lubricating oil is accurately injected into the oil storage space of the reinforcing ring through the threaded hole, and the design ensures that the lubricating oil is uniformly distributed and stored. The reinforcing ring not only serves as a structural reinforcing piece, but also ingeniously serves as a storage container of the lubricating oil, so that the maximization of space utilization is realized, and the problems of pollution and volatilization caused by the fact that the lubricating oil is directly exposed to the external environment are avoided.

Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and more specifically, it relates to a double-sided sealed deep groove ball bearing for elevators and escalators. Background Technology

[0002] Double-sided sealed deep groove ball bearings are a special type of deep groove ball bearing, with excellent sealing performance and a wide range of applications. Double-sided sealed deep groove ball bearings are also commonly used in equipment such as elevators and escalators.

[0003] In the use of double-sided sealed deep groove ball bearings, in order to ensure the sealing performance of the bearings, the maintenance of commonly used double-sided sealed deep groove ball bearings is more difficult compared to other deep groove ball bearings. This makes the maintenance of double-sided sealed deep groove ball bearings less convenient and difficult to perform, which in turn affects the normal service life of equipment such as elevators and escalators. Utility Model Content

[0004] This disclosure relates to double-sided sealed deep groove ball bearings for elevators and escalators, in order to solve the problem mentioned in the background art that, in order to ensure the sealing performance of the bearing, commonly used double-sided sealed deep groove ball bearings are more difficult to maintain than other deep groove ball bearings, resulting in lower maintenance convenience and difficulty in performing maintenance operations.

[0005] The purpose and effect of this utility model of a double-sided sealed deep groove ball bearing for elevators and escalators are achieved by the following specific technical means:

[0006] In a first aspect, this disclosure provides a double-sided sealed deep groove ball bearing for elevators and escalators, comprising: an outer bearing ring, the outer bearing ring having a circular shape and two sets of sealing rings symmetrically engaged at its upper and lower ends; the outer bearing ring further comprising: an inner bearing ring, the inner bearing ring being rotatably disposed inside the outer bearing ring; and bearing balls, the bearing balls being rotatably disposed between the inner bearing ring and the outer bearing ring.

[0007] As a preferred embodiment of this utility model, the bearing outer ring further includes: a cage, which is installed outside the bearing balls; and a sealing groove, which is circular in shape and has two sets, which are symmetrically opened at the upper and lower ends of the bearing inner ring and the bearing outer ring.

[0008] As a preferred embodiment of this utility model, the outer ring of the bearing further includes a connecting groove, the number of which is set to two sets, and the connecting grooves are symmetrically opened on the inner side of the inner ring and the outer ring of the bearing.

[0009] As a preferred embodiment of this utility model, the sealing ring further includes a reinforcing ring, which has an oil storage space inside and is integrally disposed at the bottom of the sealing ring.

[0010] As a preferred embodiment of this utility model, the sealing ring further includes: an opening, the opening being circular in shape, and the number of openings being eight, and the openings being located at the bottom of the reinforcing ring; and a fixing ring, the number of fixing rings being two sets, the fixing rings being integrally disposed outside the sealing ring and the reinforcing ring; the fixing rings engaging with the connecting groove.

[0011] As a preferred embodiment of this utility model, the sealing ring further includes: two threaded holes, which are symmetrically arranged on the top of the sealing ring; a sealing screw is rotatably installed inside the threaded hole via a threaded connection.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The use of a sealing ring greatly simplifies the maintenance process when the bearing is maintained. Simply removing the sealing screws from the threaded holes eliminates the need to disassemble complex mechanical structures; a simple operation directly reaches the core lubrication point, significantly improving maintenance efficiency, reducing downtime, and maintaining production line continuity and efficiency. Secondly, the precise injection of lubricating oil into the reinforcing ring's oil reservoir through the threaded holes ensures even distribution and storage of the lubricating oil. The reinforcing ring not only serves as a structural reinforcement but also cleverly acts as a lubricating oil reservoir, maximizing space utilization and preventing contamination and evaporation caused by direct exposure to the external environment. This ensures the cleanliness and durability of the lubricating oil. The lubricating oil flows evenly into the bearing through the opening at the bottom of the reinforcing ring, ensuring sufficient and uniform lubrication of all bearing components. This effectively reduces friction and wear caused by insufficient lubrication, extending the bearing's service life. Compared to traditional manual application or immersion lubrication, this precise lubrication method allows for more accurate control of the lubrication amount, avoiding excessive waste and preventing early failures caused by insufficient lubrication, thus improving the overall reliability and stability of the equipment.
