Abstract
The utility model discloses a belt pulley unloading mechanism which comprises a belt pulley, a bearing seat, a bearing A, an input shaft, a bearing B, a spline housing, a bearing C, a bearing D and a spindle box, wherein the bearing A is arranged on the bearing B; the input belt pulley is connected with a spline housing through a screw and a pin, the spline housing is arranged in a bearing seat through a bearing C and a bearing D, the spline housing and an input shaft are in clearance fit through spline connection, two ends of the input shaft are respectively arranged in the bearing seat and a main shaft box through a bearing A and a bearing B, and radial force generated by tightening the belt pulley is transmitted to the bearing seat through the bearing C and the bearing D and then transmitted to the main shaft box. The input shaft is not unnecessarily deformed due to improper adjustment of the belt pulley after the belt pulley is installed, primary gear transmission is affected, and unloading of the belt pulley is realized through the mechanism.
Description
Technical Field
The utility model relates to a belt pulley unloading mechanism, and belongs to the technical field of machinery.
Background
The input shaft of the spindle box is generally flexibly connected with the motor through a belt pulley, most of the belt pulleys are directly arranged on the input shaft, and the phenomenon of pulling deformation of the input shaft can be caused when the belt is excessively tight due to improper belt adjustment.
Disclosure of Invention
The utility model aims to provide a belt pulley unloading mechanism which is used for solving the problems in the background technology.
The utility model adopts the following technical scheme for realizing the purposes:
a belt pulley unloading mechanism comprises a belt pulley, a bearing seat, a bearing A, an input shaft, a bearing B, a spline housing, a bearing C, a bearing D and a main shaft box; the input belt pulley is connected with a spline housing through a screw and a pin, the spline housing is arranged in a bearing seat through a bearing C and a bearing D, the spline housing and an input shaft are in clearance fit through spline connection, two ends of the input shaft are respectively arranged in the bearing seat and a main shaft box through a bearing A and a bearing B, and radial force generated by tightening the belt pulley is transmitted to the bearing seat through the bearing C and the bearing D and then transmitted to the main shaft box.
Compared with the prior art, the utility model has the beneficial effects that: the input shaft is not unnecessarily deformed due to improper adjustment of the belt pulley after the belt pulley is installed, primary gear transmission is affected, and unloading of the belt pulley is realized through the mechanism.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: pulley 1, bearing frame 2, bearing A3, input shaft 4, bearing B5, spline housing 6, bearing C7, bearing D8, headstock 9.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1, the belt pulley unloading mechanism comprises a belt pulley 1, a bearing seat 2, a bearing A3, an input shaft 4, a bearing B5, a spline housing 6, a bearing C7, a bearing D8 and a main shaft box 9; the input belt pulley 1 is connected with the spline housing 6 through a screw and a pin, the spline housing 6 is installed in the bearing seat 2 through a bearing C7 and a bearing D8, the spline housing 6 and the input shaft 4 are in clearance fit through spline connection, two ends of the input shaft 4 are respectively installed in the bearing seat 2 and the main shaft box 9 through a bearing A3 and a bearing B5, and radial force generated by tightening the belt of the belt pulley 1 is transmitted to the bearing seat 2 through the bearing C7 and the bearing D8 and then transmitted to the main shaft box 9. In this way, the input shaft is not unnecessarily deformed by improper adjustment of the pulley 1 after installation, which affects the primary gear transmission. The unloading of the belt pulley is realized through the mechanism.
The foregoing is a preferred embodiment of the present utility model, and it will be apparent to those skilled in the art from this disclosure that changes, modifications, substitutions and alterations can be made without departing from the principles and spirit of the utility model.
