The structure is simple, and the brake, the shock absorption, the stable installation and the transmission can be considered.)

1. The utility model provides a driving three point support speed reducer, includes box, input shaft, output shaft and gear train, its characterized in that: the input end of the input shaft and the output end of the output shaft are hollow shaft sections, the end, extending out of the box body, of the non-input end of the input shaft is a brake connecting shaft section, a brake seat is externally connected to the box body below the brake connecting shaft section, and the lower part of the box body at the input end of the input shaft is connected with a supporting foot seat through a detachable pin shaft in a pin joint mode.

2. A three-point support speed reducer for a vehicle according to claim 1, wherein: the input end of the input shaft and the output end of the output shaft are positioned on different sides of the box body.

3. A three-point support speed reducer for a vehicle according to claim 1, wherein: the hollow shaft section is internally provided with a key groove.

4. A three-point support speed reducer for a vehicle according to claim 1, wherein: the supporting foot seat is pinned on a convex edge or a convex rib which is perpendicular to the input shaft on the box body.

Technical Field

The invention relates to a speed reducer, in particular to a three-point support speed reducer for a traveling crane.

Background

The speed reducer sets up the footing usually and fixes through the footing hole, but when using on the driving, all has specific requirement to speed reducer structure and service position, does not have the footing mounted position, compromises braking, shock attenuation, stable installation, driven requirement in needs, then traditional speed reducer then can't adapt to special support requirement.

Disclosure of Invention

The invention provides a three-point supporting speed reducer for traveling crane, which has a simple structure and can give consideration to braking, shock absorption, stable installation and transmission.

The technical scheme adopted by the invention is as follows: the utility model provides a driving is with three point support speed reducer, includes box, input shaft, output shaft and gear train, its characterized in that: the input end of the input shaft and the output end of the output shaft are hollow shaft sections, the end, extending out of the box body, of the non-input end of the input shaft is a brake connecting shaft section, a brake seat is externally connected to the box body below the brake connecting shaft section, and the lower part of the box body at the input end of the input shaft is connected with a supporting foot seat through a detachable pin shaft in a pin joint mode.

The input end of the input shaft and the output end of the output shaft are positioned on different sides of the box body.

The hollow shaft section is internally provided with a key groove.

The supporting foot seat is pinned on a convex edge or a convex rib which is perpendicular to the input shaft on the box body.

The invention adopts the support foot seat in pin joint with the lower part of the input end of the input shaft, the brake seat under the non-input end of the input shaft and the external support of the output shaft, and three-point type suspension support is carried out on the whole speed reducer by three-point support without arranging bottom feet.
