Description
Technical Field
The invention relates to a clamp, in particular to a clamp for press-fitting a gear ring of a reverse gear synchronizer.
Background
Because the transmission input and output shafts rotate at respective speeds, there is a "synchronization" problem in shifting gears. The gears with different rotation speeds are forcedly meshed, so that impact collision can be caused, and the gears are damaged. Therefore, the old-fashioned transmission is shifted by adopting a mode of 'two-foot clutch', the upshift stays in the neutral position for a moment, and the downshift is to add the accelerator in the neutral position so as to reduce the rotation speed difference of gears. However, this operation is complicated and difficult to grasp accurately. The designer therefore creates a "synchronizer" by which gears to be engaged are brought to a uniform rotational speed for smooth engagement.
The component of the reverse gear synchronizer comprises a tooth sleeve, wherein the tooth sleeve is annular, teeth are arranged on the inner wall, and the component further comprises a tooth ring, and the tooth ring is assembled on the tooth sleeve through press fitting. As a representation of the production process level, and at the same time, the requirement of the quality of the finished product, how to safely, conveniently and smoothly assemble the toothed ring on the toothed sleeve is a problem that the production enterprises have to consider. The existing assembly modes are mostly assembled manually by workers, so that on one hand, the efficiency is low, and on the other hand, the smoothness in the assembly process is poor, and the quality of products is unstable.
