Problems solved by technology

In order to ensure that the gear sleeve produced meets the requirements, it is necessary to perform M value detection on the teeth on the inner wall of the gear sleeve. The existing M value detection method is to use a hand-held inspection tool for manual detection, which is cumbersome and inefficient.

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] Such as Figure 1 to Figure 3 The M-value test tool for the internal teeth of a synchronizer gear sleeve shown has a base plate 1, and the upper surface of the base plate 1 is provided with a fixed probe base 2 and a movable probe base 3 that can move forward and backward. The upper surface of the base plate 1 Bar-shaped setting grooves are arranged along the front-rear direction. The fixed probe base 2 is fixedly arranged in the setting groove, and the movable probe base 3 is slidably fitted in the setting groove. A spherical probe 4 is arranged on the fixed probe base 2 and the movable probe base 3 respectively, and the two probes 4 are arranged on a straight line, and the probe 4 on the fixed probe base 2 and the movable probe base 3 Pointing forward and backward respectively.

[0022] Such as Figure 1 to Figure 3 As shown, the bottom plate 1 i...

Abstract

The invention discloses a synchronizer gear sleeve inner tooth M value gauge. The gauge includes a bottom plate, wherein an upper surface of the bottom plate is provided with a fixed probe holder anda movable probe holder capable of moving forward and backward side by side, the fixed probe holder and the movable probe holder are respectively provided with a spherical probe, the two probes are placed on a straight line, the probes on the fixed probe holder and the movable probe holder respectively point to the front portion and the rear portion, the bottom plate is provided with a spring whichcan push the movable probe holder backward, the movable probe holder is connected with a detection block capable of moving forward and backward, the detection block is arranged behind the movable probe holder, a dial indicator is mounted on the bottom plate, and a detection head of the dial indicator points to the detection block. The gauge is advantaged in that the concept is novel, design is reasonable, the gauge is easy to use, the M value of an inner tooth of the gear sleeve is indirectly measured by a jaw structure formed by the fixed probe holder and the movable probe holder, compared with the prior art, operation is simpler, and overall efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of synchronizer production, and in particular relates to a tool for checking the M value of inner teeth of a synchronizer gear sleeve. Background technique [0002] Since the transmission input shaft and output shaft rotate at separate speeds, there is a "synchronization" problem when changing gears. Two gears with different rotation speeds are forcibly meshed, and impact collisions will inevitably occur, which will damage the gears. Therefore, the gear shifting of the old-fashioned transmission should adopt the "two-leg clutch" method, and the upshift should stay in the neutral position for a while, and the downshift should be fueled in the neutral position to reduce the speed difference of the gears. But this operation is more complicated and difficult to master accurately. Therefore, the designer created a "synchronizer", through which the gears to be meshed can reach a consistent speed and mesh smoothl...
