Bearing puller

Abstract

A puller device which is used for detaching an annular component from an assembling shaft thereof comprises a supporting platform, a maintaining mechanism and a driving mechanism. The supporting platform is used for bearing internal stress generated by the puller device in an operation process. The maintaining mechanism is supported by the supporting platform and is used for preventing the annular component from moving in the axial direction in a detaching process. A pair of pulling blocks is arranged at the tail end of the maintaining mechanism in the longitudinal direction, can surround the assembling shaft to form a pair of lips of which the radial sizes correspond to the radial size of the annular component after being folded, and is used for fastening an end surface of one side of the annular component in a detaching process to prevent the annular component to move along the assembling shaft in the axial direction in a detaching process. The driving mechanism is supported by the supporting platform, and is used for applying a separation acting force to the assembling shaft in a detaching process to force the assembling shaft to be separated from the annular component in the axial direction. The lips of the pair of pulling blocks are opposite, and are arranged on a pair of parallel sliding rods in parallel in a striding manner. At least one pulling block can move along the pair of sliding rods so as to adjust the distance between the pulling block and the other pulling block, and the pulling block can be positioned on the pair of sliding rods in a lockable mode through a positioning component.

Description

technical field [0001] The present invention relates to a bearing puller apparatus capable of detaching an annular member such as a bearing from its assembly shaft. Background technique [0002] Bearing pullers can disassemble bearings and other annular components from mounting shafts, and thus are widely used in the field of bearings. exist figure 1 In the shown perspective view, the puller 1 as a whole includes: a support platform (support platform) 10 that is sufficient to withstand the internal force of the system generated during pulling; Actuator means 20 for the driving force required to break free from the tightening action of the bearing 50; and a holder means 30 for ensuring that the bearing 50 remains axially positioned relative to the support platform 10 when drawing. [0003] Existing bearing pullers are formed in various shapes and structures according to their purposes. figure 1 The puller shown in is a puller mainly used for removing the bearing on the mac...

Problems solved by technology

Obviously, this process is quite time-consuming and inconvenient to use the nut adjustment

To make matters worse, when using nut positioning, the nut positioning can only limit the movement of the drawing block from one side

If the drawing block is not really close to the nut, it is actually in an unstable active state during the drawing process, and it is easy to slide in any direction along the threaded rod, either scratching the surface of the assembly shaft inward, or pulling it outward Buckled on the rolling element, cage or even the outer ring of the bearing, resulting in accidents
