The main shaft structure of the existing traction machine is characterized in that a spline is directly machined at the end part of the main shaft, and in the machining process of the main shaft structure, multiple machining methods are needed to be used for machining the spline, so that the spline cannot be machined by a one-time lathe, the machining efficiency is low, and the cost is high; and the main shaft after processing is difficult to maintain after being worn.

Disclosure of Invention

The purpose of the utility model is that: the utility model provides a hauler main shaft with spline housing to solve the problem among the prior art.

The utility model is realized by the following technical scheme: a hauler main shaft with spline housing, its characterized in that:

the device comprises a main shaft body, wherein a bearing platform is arranged at one end of the main shaft body, and a key groove is arranged on the bearing platform;

the inner hole of the spline housing is circular, the inner diameter of the spline housing is matched with the outer diameter of the bearing platform, a key groove is formed in the inner diameter surface of the spline housing, and a spline is arranged on the outer surface of the spline housing;

the spline sleeve is characterized by further comprising a gland, wherein the gland is fixed at the end part of the bearing platform through a bolt, and the outer diameter of the gland is larger than the inner diameter of the spline sleeve.

Further: the bearing platform is cylindrical and integrally arranged at the end part of the main shaft body.

Detailed Description

The utility model discloses a traction machine main shaft with a spline housing, which comprises a main shaft body 1, wherein a bearing platform 6 is arranged at one end of the main shaft body, and a key groove is arranged on the bearing platform; the novel spline sleeve comprises a spline sleeve body, and is characterized by further comprising a spline sleeve 2, wherein an inner hole of the spline sleeve body is circular, the inner diameter of the spline sleeve body is matched with the outer diameter of a bearing platform, a key groove is formed in the inner diameter surface of the spline sleeve body, the key groove of the bearing platform is matched with the key groove of the spline sleeve body, a flat key 3 is arranged between the key groove of the bearing platform and the key groove of the spline sleeve body, and a spline 7 is arranged on the outer surface of the spline sleeve body; the novel spline sleeve is characterized by further comprising a gland 4, wherein the gland is fixed at the end part of the bearing platform through a bolt 5 or a countersunk screw, and the outer diameter of the gland is larger than the inner diameter of the spline sleeve.

Preferably: the bearing platform is cylindrical and integrally arranged at the end part of the main shaft body.

Preferably: the outer end face of the spline housing is provided with a step, so that a groove-shaped space capable of accommodating the gland is formed on the spline housing, the gland is matched with the step, and after the gland presses the spline housing, the outer end face of the gland is flat with the spline housing. The structure shortens the whole length of the assembled main shaft and saves space.

The assembly process of the utility model is as follows:

during assembly, the main shaft is placed first, and then the flat key is installed in the key groove of the main shaft. After the flat key is installed, the spline housing is installed on the main shaft along the direction of the flat key, and the spline housing is necessarily installed on the root position of the main shaft. And finally, installing a gland, installing countersunk screws into the corresponding holes, and locking and fixing. Thus, the main shaft and the spline housing are connected together, and the assembly of the structure is completed.

In the assembly and installation of the traction machine, the main shaft is a key component, basically, the traction machine needs a mounting structure of the component, and the main shaft can provide effective rotation and braking for the traction machine.
