Abstract

The utility model discloses a transmission shaft structure of a loader, which comprises a transmission shaft (1) and a gap bridge shaft (4), wherein one end of the transmission shaft (1) is fixedly connected with one end of the gap bridge shaft (4) through welding; the other ends of the transmission shaft (1) and the bridge shaft (4) are fixed on a side plate of the loader through bearings; the problem of prior art loader's transmission shaft structure's transmission shaft and the one end of passing the axle shaft carry out swing joint through the bearing, pass the frequent damage of connection bearing in the use is solved.

Description

Transmission shaft structure of loader

Technical Field

The utility model relates to a coal dressing machinery technical field especially relates to a loader transmission shaft structure.

Background art:

the transmission shaft structure of the loader for the coal mine comprises a transmission shaft and a gap bridge shaft, and one end of the transmission shaft and one end of the gap bridge shaft are movably connected through a bearing in a connection mode; the other ends of the transmission shaft and the gap bridge shaft are respectively fixed on a side plate of the reversed loader through bearings; in the actual use process, the torque of a transmission shaft of the loader is found to be large in the turning process, the connecting bearing of the transmission shaft and the gap bridge shaft is frequently damaged due to the influence of the torque, the service life of the transmission shaft is shortened, and the bearing is damaged and is not easy to replace due to various factors, so that the production is seriously restricted.

The utility model has the following contents:

the utility model discloses the technical problem who solves: the utility model provides a loader transmission shaft structure to solve the transmission shaft of the transmission shaft structure of prior art loader and the one end of passing the axle and carry out swing joint through the bearing, cross the frequent problem of damaging of connection bearing in the use.

The utility model discloses technical scheme:

a transmission shaft structure of a loader comprises a transmission shaft and a gap bridge shaft, wherein one end of the transmission shaft is fixedly connected with one end of the gap bridge shaft through welding; the other ends of the transmission shaft and the bridge shaft are fixed on a side plate of the loader through bearings.

And the shaft heads at one ends of the transmission shaft and the gap bridge shaft respectively extend into the shaft sleeves and are welded with the shaft sleeves.

The utility model has the advantages that:

the utility model removes the bearing connected between the transmission shaft and the gap bridge shaft, only the shaft sleeve is reserved, and the transmission shaft and the gap bridge shaft are welded and fixed with the shaft sleeve to form rigid connection; the utility model discloses a so adopt the mode of demolising original bearing is for reducing the transformation cost, when the loader is big at turn in-process transmission shaft moment of torsion, can not produce and rock and distort, avoid connecting the bearing and damage owing to receiving the moment of torsion influence, transmission shaft life has been improved, production cost is reduced, the transmission shaft of the transmission shaft structure of having solved prior art loader carries out swing joint through the bearing with the one end of crossing the axle, cross the problem of connecting the frequent damage of bearing in the use.

Description of the drawings:

FIG. 1 is a schematic view of the connection structure of the present invention;

fig. 2 is the utility model discloses whole effect schematic diagram after the welding.

The specific implementation mode is as follows:

a loader transmission shaft structure comprises a transmission shaft 1 and a gap bridge shaft 4, wherein a connecting bearing between the transmission shaft 1 and the gap bridge shaft 4 is removed, only a shaft sleeve 2 is reserved, shaft heads at one ends of the transmission shaft 1 and the gap bridge shaft 4 respectively extend into the shaft sleeve 2, and the shaft heads and the shaft sleeve 2 are welded to form rigid connection; so as to form a new transmission shaft structure 3; the other ends of the transmission shaft 1 and the gap bridge shaft 4 are fixed on a side plate of the loader through bearings. So that the new transmission shaft is driven by the motor to operate.
