Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The tool for centering and pressing the tapered roller bearing outer ring for the steering gear comprises a guide disc 1, a pressing rod 2, a pressing block 3 and a guide block 4; one end of the pressing rod 2 is detachably connected with the pressing block 3, and the pressing block 3 is detachably connected with the guide block 4; the bearing outer ring 5 is fixed on the guide block 4, the bottom of the guide block 4 is in interference fit with the contact part of the bearing outer ring 5 to be pressed in, the compression bar 2 is matched with the inner hole of the guide disc 1, and the guide disc 1 is matched with the steering gear shell hole.
Further, the central hole at the bottom of the housing 6 of the steering gear and the central hole of the upper installation guide plate 1 are processed concentrically.
Further, the guide block 4 includes an integrally formed connecting portion 3.1 and an outer ring fixing portion 3.2; the external diameter of the connecting part 3.1 is a conical surface matched with the internal diameter of the bearing outer ring 5 to be pressed in, and the bottom end of the outer ring fixing part 3.2 is in interference fit with the edge of the bottom of the internal diameter of the bearing outer ring 5 to be pressed in.
Furthermore, the outer ring fixing part 3.2 is provided with four locking claws, the inner sides of the locking claws are provided with annular grooves 7, and the annular grooves 7 can increase the elasticity of the locking claws.
