Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe roller press-fitting, in particular to a brake shoe roller bushing press-fitting device. Background Art

[0002] The brake shoe roller bushing is a part installed on the brake drum or brake disc to reduce the friction and wear generated during the braking process. When replacing the brake shoe roller bushing, it is often necessary to perform a press-fit operation. Press-fitting of brake shoe roller bushings refers to the process of installing a new bushing on a brake drum or brake disc. At present, the brake shoe roller bushings are all manually aligned during press-fitting, but manual alignment is prone to displacement of the bushing and roller during press-fitting, resulting in misalignment of the bushing and roller, which in turn affects the press-fitting accuracy of the bushing and roller.
