Comparison gauge for detecting distance between inner hole snap spring groove and outer end face of bevel gear

Abstract

The invention relates to a comparison gauge for detecting the distance between an inner hole snap spring groove and an outer end face of a bevel gear. The comparison gauge comprises a bottom plate, abase, a positioning sleeve, a measuring rod, a dial indicator, a support, a gauge body and a compression spring. The base and the support are fixed to the bottom plate. A groove is formed in the base.An eccentric hole is formed in the bottom face of the groove. The positioning sleeve can be inserted in the eccentric hole and inserted in the base. The compression spring can be inserted in a hole of the positioning sleeve. A boss is arranged on the measuring rod. The measuring rod can be inserted in the spring along the hole of the positioning sleeve, and the depth at which the measuring rod isinserted in the spring is limited by the boss. The comparison gauge for detecting the distance between the inner hole snap spring groove and the outer end face of the bevel gear is simple in measurement structure, easy to manufacture and convenient to use.

Description

technical field [0001] The invention relates to a special inspection tool for the structural size of mechanical parts, in particular to a comparison inspection tool for the distance between the ring groove of the inner hole of the bevel gear and the outer end surface. Background technique [0002] Bevel gears are a common mechanical part, and most of these rotating mechanical parts are positioned and installed with inner holes. For the inner hole of the bevel gear matched with some precision machinery, a ring groove is usually provided, and the ring groove is used to cooperate with the shaft matching circlip or retaining ring to act as an axial limit. For example, there is a ring groove (ring groove) in the inner hole of the side gear in the automobile differential, and the size of the ring groove in the inner hole and the outer end surface of the gear is limited. Such as figure 1 (Schematic diagram of the ring groove structure in the inner hole of the bevel gear), L is th...
