Embodiment Construction

[0070] Next, embodiments of the present invention will be described. In this embodiment, a gear component and its coupling jig configured as a reduction gear component in a front-engine and front-wheel drive automotive transmission will be described as an example.

[0071] Below, refer to figure 1 Be explained. figure 1 It is a perspective view showing the gear part 20 and the coupling jig 10 before the nut 30 is tightened.

[0072] The gear part 20 is formed by integrating a gear shaft 21 and a second gear 23, and bearings 24 and 25 are provided at both ends. In addition, in figure 1 The middle table shows the inner rings 24a, 25a and rollers 24b, 25b of the bearings 24, 25, and the outer rings are omitted. At one end of the gear shaft 21 on which the second gear 23 and the bearing 24 are mounted, a nut 30 is fastened to prevent the second gear 23 from coming off.

[0073] The gear shaft 21 is composed of a shaft portion 200 and a first gear 22 which are integrally fo...

Abstract

A gear part, a connection clamp and an assembly method of the gear part are disclosed. When a thread part is fastened on the gear part, a simple method is sued for stop the rotation. According to the gear part (20), a nut (30) fastened on a shaft part (200) is used to prevent a second gear (23) of a spline part (201) of a gear shaft (21) from revolving. A through hole (210) is provided at the shaft end of the shaft part with an embedment part (221) for making the top point of a triangle into an arc-shaped cross section. The nut is joined at the shaft end side at one side of the second gear inserted into the spline part, and the embedment part is arranged on the shaft end opposite to the second gear. In the embedment part of the shaft part, a minor diameter part (222) of a round cross section with a diameter smaller than the embedment part is coaxially connected.

Description

technical field [0001] The invention relates to a gear part, a coupling fixture and an assembly method of the gear part. Background technique [0002] In transmissions used in automobiles, etc., a gear component consisting of a plurality of gears or bearings fitted on a shaft is used. [0003] For such gear parts, after fitting gears, bearings, etc. to the shaft, screw parts such as nuts are fastened to the end of the shaft to prevent them from coming off. In this way, when such a threaded part is fastened to the shaft, it is necessary to prevent rotation (rotation stop) in order to prevent the shaft from idling. [0004] As a technique for preventing the rotation of such gear parts, there is currently a technique of forming protrusions such as double-sided (two-sided width) intervals at the end of the gear parts, and using a jig that fits into the protrusions of the gear parts. Perform stop rotation. [0005] Figure 5 It is a figure showing such a conventional gear comp...
