Abstract
The utility model relates to a full complement ball bearing spacing block, this spacing block are annular appearance structure, and the inner ring has with the endocentric arc pocket hole of steel ball, and the contact area of steel ball on spacing block and the bearing is convex, places along the centre of turning circle footpath interval of steel ball in the bearing, and the PGM combined material of spacing block material for having self-lubricating function. By adopting the utility model, the contact state of the spacing block and the steel ball can be improved, the rotation precision is improved, and the consumption of lubricating grease can be reduced by the PGM; the isolating blocks are arranged in the bearing at intervals along the diameter of the rotation center of the steel ball, so that the number of isolating blocks of each set of bearing is reduced, and the assembly efficiency is improved.
Description
Technical Field
The utility model relates to a full complement ball bearing spacing block, especially antifriction bearing technical field.
Background
The isolation block mainly has the functions of replacing a retainer to realize the functions of isolating the rolling body, guiding the rolling body and storing lubricating grease, and is widely applied to slewing bearing bearings of missile launcher, radar antenna pedestal, tank, navigation instrument and the like. Traditional spacing block mainly installs on cylindrical roller bearing, four point contact ball bearing, and the material generally is two main types of nylon and metal, and its structure and material characteristic can't satisfy the requirement that full dress ball bearing space is limited, high rotational accuracy operating condition, consequently need propose a new construction spacing block, are applicable to the demand that the inner space is limited, the full dress ball bearing of high rotational accuracy requirement.
Disclosure of Invention
The utility model discloses the purpose is under the limited condition in space, designs out high rotation accuracy, has a full complement ball bearing spacing block of self-lubricating characteristics.
The utility model adopts the technical proposal that: a full-complement ball bearing isolation block is characterized in that the isolation block is of an annular appearance structure, an inner ring is provided with an arc-shaped pocket concentric with a steel ball, the contact area of the isolation block and the steel ball on a bearing is arc-shaped, and the isolation block and the steel ball on the bearing are arranged at intervals in the bearing along the rotation center diameter of the steel ball.
The fully-loaded ball bearing spacer block is characterized in that the spacer block is made of PGM composite materials with self-lubricating functions.
By adopting the utility model, the contact state of the spacing block and the steel ball can be improved, the rotation precision of the steel ball can be improved, and the self-lubricating material PGM can reduce the friction and wear between the steel ball and the spacing block and reduce the usage amount of lubricating grease; the isolating blocks are arranged in the bearing at intervals along the diameter of the rotation center of the steel ball, so that the number of isolating blocks of each set of bearing is reduced, and the assembly efficiency is improved.
Drawings
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is a schematic sectional view of the present invention.
Figure 3 is a schematic view of the present invention installed into a bearing.
The numbers in the figure indicate: the steel ball bearing comprises a spacer block 1, a steel ball 2, an arc-shaped pocket 3, an annular shape 4, an outer ring 5 and an inner ring 6.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the spacer block 1 of the full complement ball bearing spacer block is in an annular shape 4, an inner ring of the spacer block 1 is provided with an arc-shaped pocket 3 concentric with a steel ball, a contact area with the steel ball 2 on the bearing is in an arc shape, and the spacer block is arranged in the bearing at intervals along the rotation center diameter of the steel ball 2. The spacer 1 is made of self-lubricating composite PGM.
The bearing comprises an outer ring 5, a steel ball 2, a spacer block 1 and an inner ring 6 from outside to inside in sequence, wherein the inner ring 6 is sleeved inside the outer ring 5, the steel ball 2 is placed between the outer ring 5 and the inner ring 6, the steel ball 2 is pressed into an arc-shaped pocket hole 3 through the end face of the spacer block 1, the arc-shaped pocket hole 3 can improve the contact state of the spacer block and the steel ball, the rotation precision of the spacer block is improved, the friction wear of the steel ball 2 and the spacer block 1 can be reduced by a self-lubricating material PGM, and the; the isolating blocks 1 are arranged in the bearing at intervals along the diameter of the rotation center of the steel ball 2, the structure of the isolating blocks 1 ensures that one isolating block can isolate three adjacent steel balls 2, the number of the isolating blocks 1 of each set of bearing is reduced, and the assembly efficiency is improved.
Claims (2)
1. A full-complement ball bearing isolation block is characterized in that the isolation block is of an annular appearance structure, an inner ring is provided with an arc-shaped pocket concentric with a steel ball, the contact area of the isolation block and the steel ball on a bearing is arc-shaped, and the isolation block and the steel ball on the bearing are arranged at intervals in the bearing along the rotation center diameter of the steel ball.
