Abstract
An axle center fixer of conical-surface steel ball belongs to the technical field of industrial machinery and is composed of a body, a fixed sheet, steel balls, a movable sheet and a shaft component. The fixed sheet (2) with a conical opening is equipped in the body (1). A plurality of steel balls (3) are arranged in a V-shaped groove of an external circle of the shaft (5). The shaft (5) which is provided with the steel balls (3) passes through the body (1) and contacts with the conical opening of the fixed sheet (2). The movable sheet (4) passes through the shaft (5) and contacts with the steel balls (3) through the screw matched with the body (1). After assembling, no clearance exists in the axial direction and no clearance exists in radial centering. The shaft with large diameter or small diameter can be matched. The axle center fixer of conical-surface steel ball further has the advantages of no structural dimension restriction, low manufacturing cost and convenient installation and use. The axle center fixer of conical-surface steel ball is widely used for shaft centering of mechanical component.
Description
Technical field: belong to the industrial machinery technical field.
Background technique: common representative axle class Roll centering parts have only bidirectional angular contact thrust ball bearing and thrust ball bearing at present, they are felt relieved with ball, axially, radially error are arranged all, and centering precision is low, the processing technology complexity, physical dimension limits within the specific limits.
Summary of the invention: the purpose of this utility model provides a kind of conical surface steel ball dead axle concentric mechanism, and it is made up of body, stator, steel ball, moving plate, axle part.Axle is contained on the body, does not axially have the gap, radial centering does not have the gap, and big small axle diameter can both be supporting, not limited by physical dimension, and processing cost is low, and is easy to install, is widely used.
The utility model is made up of body (1), stator (2), steel ball (3), moving plate (4), axle (5) part, and it is characterized in that: body has through hole on (1), and a side of through hole is a screw-threaded counterbore, and the stator (2) that has conical bore is contained in the body (1); Several steel balls (3) are arranged in the V-shaped groove of cylindrical of axle (5); The axle (5) that steel ball (3) are installed passes body (1) and contacts with the conical bore of stator (2); Moving plate (4) passes axle (5), contacts with steel ball (3) by the screw thread with body (1) cooperation.
Description of drawings: this figure is a structure principle chart of the present utility model.
Embodiment: model utility is achieved in that by shown in the figure, when turning moving plate (4), several steel balls (3) simultaneously along the conical surface of stator (2), moving plate (4) to the axle center slippage, when tightening moving plate (4), steel ball (3) all is pressed in the V-shaped groove of axle (5), (3) four of each steel balls are even stressed simultaneously, moving plate (4) does not have retaining again under the effect of steel ball (3) counter-force, when rotatingshaft (5), reached axial no gap, radial centering does not have the gap.
Claims (1)
1. conical surface steel ball dead axle center device is made up of body (1), stator (2), steel ball (3), moving plate (4), axle (5) part, it is characterized in that: body has through hole on (1), one side of through hole is a screw-threaded counterbore, and the stator (2) that has conical bore is contained in the body (1); Several steel balls (3) are arranged in the V-shaped groove of cylindrical of axle (5); The axle (5) that steel ball (3) are installed passes body (1) and contacts with the conical bore of stator (2); Moving plate (4) passes axle (5), contacts with steel ball (3) by the screw thread with body (1) cooperation.
