Abstract
The utility model discloses a mining DC traction motor, which comprises a shell with an end cover, a brush carrier arranged in the shell, and a junction box. By adopting the structure that the junction box is arranged on the outer wall of the end cover and the brush carrier is arranged on the inner wall of the end cover to enable that the brush carrier, the junction box and the end cover can be relatively fixed into a whole, the brush carrier and the junction box can be simultaneously disassembled when the end cover is disassembled for mounting and maintenance, so that the disassembly and assembly during wiring between the brush carrier and the junction box are more convenient; in addition, an insertion space is only needed to reserve in advance for a cylindrical shell if the motor is mounted along the axial direction of a rotating shaft of the motor, so that the mounting space can be saved at a certain extent.
Description
Technical field
The utility model belongs to the electric motor structure design field, is specifically related to a kind of mining DC traction motor.
Background technology
The terminal box of flame-proof mine DC traction motor, operated by rotary motion is on the periphery of motor cylinder shape housing, as shown in Figure 1.In this kind structure, described brush holder brush holder is fixed on the electric motor end cap inwall, and the line of carbon brush then will be connected on the binding post that is positioned at terminal box on the casing outer circumferential walls, need operate by the peep pole that is positioned at the casing top during connection; Because the peep pole of miniature motor (7.5kw is following) is very little, attended operation is very inconvenient.In addition, because terminal box is arranged on the periphery of tubular shell, so need be the terminal box headspace on the motor external circumferential, if motor is to pack into along its rotation axis axial direction, the terminal box of this structure occupies big installing space with needs.
Summary of the invention
The mining comparatively easily DC traction motor of wiring dismounting operation when the purpose of this utility model provides a kind of installation maintenance.
The technical scheme that realizes the utility model purpose is: a kind of mining DC traction motor comprises housing with end cap, is located at brush holder and terminal box in the housing; Described terminal box is arranged on the outer wall of end cap, and described brush holder is arranged on the inwall of end cap.
Described end cap is provided with the rotation axis shaft-jointed hole, and the quantity of described terminal box is two, and is symmetricly set on the both sides of described shaft-jointed hole.
Described end cap is provided with installing hole, is provided with binding post in the described terminal box, and described binding post runs through installing hole on the end cap and described installing hole is all exposed at the head and the tail two ends of described binding post.
The utlity model has positive effect:
(1) in the utility model, described terminal box is arranged on the outer wall of end cap, and described brush holder is arranged on the inwall of end cap.This kind structure makes described brush holder, terminal box and end cap three relative fixed be integral, and when installation and maintenance, also brush holder and terminal box is unloaded when end cap is unloaded, and makes that wiring dismounting and the installation between brush holder and the terminal box is all comparatively convenient.In addition, if motor is to pack into along its rotation axis axial direction, will only needs to reserve the plug-in mounting space, thereby on certain condition, save installing space for tubular shell.
(2) in the utility model, described end cap is provided with installing hole, is provided with binding post in the described terminal box, and described binding post runs through installing hole on the end cap and described installing hole is all exposed at the head and the tail two ends of described binding post.This kind structure is because binding post runs through end cap, and therefore the line between more convenient brush holder and the binding post is operated.
Description of drawings
Fig. 1 is a kind of structural representation of conventional motors;
Fig. 2 is a kind of structural representation of the present utility model.
Be labeled as shown in the accompanying drawing: housing 1, end cap 11, rotation axis shaft-jointed hole 12, installing hole 13, brush holder 2, terminal box 3, binding post 31.
Embodiment
(embodiment 1)
Fig. 2 is a kind of structural representation of the present utility model, has shown a kind of structural representation of the present utility model.
Present embodiment is a kind of flame-proof mine DC traction motor, sees Fig. 2, comprises housing 1 with end cap 11, is located at brush holder 2 and terminal box 3 in the housing 1; Described terminal box 3 is arranged on the outer wall of end cap 11, and described brush holder 2 is arranged on the inwall of end cap 11.
Described end cap 11 is provided with rotation axis shaft-jointed hole 12, and the quantity of described terminal box 3 is two, and is symmetricly set on the both sides of described shaft-jointed hole 12.
Described end cap 11 is provided with installing hole 13, is provided with binding post 31 in the described terminal box 3, and described binding post 31 runs through installing hole 13 on the end cap 11 and described installing hole 13 is all exposed at the head and the tail two ends of described binding post 31.
Present embodiment has the following advantages:
(1) in the present embodiment, described terminal box 3 is arranged on the outer wall of end cap 11, and described brush holder 2 is arranged on the inwall of end cap 11.This kind structure makes described brush holder, terminal box and end cap three relative fixed be integral, and when installation and maintenance, also brush holder and terminal box is unloaded when end cap is unloaded, and makes that wiring dismounting and the installation between brush holder and the terminal box is all comparatively convenient.In addition, if motor is to pack into along its rotation axis axial direction, will only needs to reserve the plug-in mounting space, thereby on certain condition, save installing space for tubular shell.
(2) in the present embodiment, described end cap 11 is provided with installing hole 13, is provided with binding post 31 in the described terminal box 3, and described binding post 31 runs through installing hole 13 on the end cap 11 and described installing hole 13 is all exposed at the head and the tail two ends of described binding post 31.This kind structure is because binding post runs through end cap, and therefore the line between more convenient brush holder and the binding post is operated.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
