Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
A centering press-in tool for an outer ring of a tapered roller bearing for a steering gear comprises a guide disc 1, a pressure rod 2, a pressing block 3 and a guide block 4; one end of the pressure rod 2 is detachably connected with a pressing block 3, and the pressing block 3 is detachably connected with a guide block 4; bearing inner race 5 is fixed on guide block 4, and 4 bottoms of guide block and the 5 contact site interference fit of bearing inner race of waiting to impress, depression bar 2 and the cooperation of 1 hole of deflector, deflector 1 and steering gear casing hole cooperation.
Further, the central hole at the bottom of the shell 6 of the steering gear and the central hole of the upper installation guide disc 1 are processed concentrically.
Further, the guide block 4 comprises a connecting part 3.1 and an outer ring fixing part 3.2 which are integrally formed; the outer diameter of the connecting part 3.1 is a conical surface matched with the inner 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 bottom edge of the inner 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 elasticity of the locking claws can be increased by the annular grooves 7.
