RU85585U1 - BALL BEARING RADIAL SINGLE ROW - Google Patents

Abstract

Single row deep groove ball bearing containing an inner ring, an outer ring, balls, a cage, characterized in that the cage is made of two riveted bronze parts with sixteen sockets for balls in each part, the inner ring, the outer ring and balls are made of heat-resistant steel 8X4V9F2-Sh.

Description

The utility model relates to the field of mechanical engineering, in particular to ball bearings.

The closest analogue is a rolling bearing containing an inner ring, an outer ring, balls, a cage (see, for example, the description of the invention to patent RU 2262014, IPC F16C 19/00, 33/30, publication date 10.10.2005).

The disadvantage of the closest analogue is not high enough reliability.

The technical result of the claimed solution is to increase reliability.

The essence of the technical solution is characterized by the fact that it contains an inner ring, an outer ring, balls, a separator, the outer ring is single-breasted with a lock, the separator is made of two bronze fastened parts with sixteen sockets for balls in each part, the inner ring, the outer ring and balls are made of heat resistant steel.

The essence of the technical solution is illustrated by the drawing, where figure 1 shows a view in section.

The radial single-row ball bearing contains an inner ring 2, an outer ring 1, balls 3, a cage 4. The cage 4 is made of two bronze parts riveted together with sixteen nests for balls in each part of the cage. The inner ring 2, the outer ring 1 and the balls 3 are made of heat-resistant steel 8X4V9F2-Sh.

Balls 3 in the amount of 16 pieces are located in sixteen sockets of the separator 4. The claimed bearing was made with an outer diameter of the outer ring of 168 mm with a tolerance of -0.011 mm and a width of the outer ring of 19 mm with a tolerance of -0.12 mm, with an inner diameter of the inner ring of 240 mm with a tolerance of -0.01 mm. The specified number of balls 3 provides the specified requirements for dynamic load capacity. The diameter of the balls, the shape of the raceways of the outer ring 1 and the inner ring 2 are made by optimizing sizes according to well-known calculation methods (see, for example, Balyakin V.B., Zhilnikov EP, Samsonov VN, Makarchuk VV Theory and design of supports for rotors of aircraft gas turbine engines - Samara: Publishing House of Samar State University, 2007, pp. 93-234). The number of balls 3 with the number of 16 pieces was also selected as a result of optimization in order to ensure durability and reliability at specified loads on the axes of rotation.

Bearing ball radial single row works as follows. When the inner ring 2 and / or the outer ring 1 rotate, the workload is transferred between the rings 1 and 2 through the balls 3, while the balls 3 are set in motion. Each ball 3 rotates around its axis of rotation and all the balls 3 move in a circle along with the separator 4.

The design of the separator 4, the optimal selection of the number of balls 3, the choice of material of the rings 1, 2, balls 3 provides increased reliability of the bearing.
