Abstract

The utility model discloses a motor. The motor comprises a rotating shaft and a stand, wherein at least one positioning seam allowance of which the axis is coincided with the axis of the rotating shaft is arranged in the peripheral direction of the stand; one end of the stand is provided with a convex ring; the peripheral surface of the convex ring is provided with the positioning seam allowance; the convex ring is also provided with a hinge hole of which the axis is parallel to the axis of the positioning seam allowance; and the rotating shaft is a C4 clearance roller bearing. Compared with the prior art, the motor provided by the utility model has a simple and compact structure and an obvious effect; the fixed connection mode of the stand and a wheel hub in the prior art is changed under the condition that the appearance of the motor slightly changes; the connection mode of the stand and the wheel hub is changed in the way that the stand and the wheel hub are positioned through the convex ring in the circumferential direction; the axial position of the motor is positioned through the positioning seam allowance for guaranteeing coaxiality; and a gear on the rotating shaft is connected with a reduction gear on the wheel hub to transfer torque, so that the aims of making overhauling convenient, saving time, improving production efficiency and prolonging maintenance-free period are fulfilled.

Description

A kind of motor
Technical field
The utility model relates to mechanical manufacturing field, relates in particular to a kind of motor.
Background technology
Motor is the device that converts electric energy to mechanical energy, particularly asynchronous motor as the power of manufacturing machine operation, have simple in structure, be easy to advantages such as control, efficient height and power are big, be widely used in the modern various machinery as drive unit.Mostly large power, electrically driving wheel ac variable-frequency electric motor is to install and use in the large-scale mine dumper at present.Motor casing and hub spindle are made of one structure, but because equipment needs periodic inspection, bother very much during dismounting, often need to spend great amount of manpower, material resources.Locomotive often operates in non-highway pavement, especially when the empty wagons backhaul, vibrates bigger.Bearing adopts the general bearing that rolls, and is shorter in the following life-span of this vibration.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, is guaranteeing that electric machine structure changes not quite, under the impregnable prerequisite of performance, provides a kind of reliability height, degree of protection height, easy accessibility, long motor of non-maintaining cycle.
The utility model adopts following technical scheme to realize:
A kind of motor comprises rotating shaft and support, it is characterized in that, the periphery of support upwards is provided with the positioning spigot that its axis overlaps with shaft axis at least.
Further, an end of described support is provided with bulge loop, and the outer peripheral face of this bulge loop is described positioning spigot, also is provided with the articulation hole of the parallel axes of its axis and positioning spigot on bulge loop.
Further, described rotating shaft is a C4 play roller bearing.
Compared with prior art, electric motor structure of the present utility model is simple, compact, action effect is obvious, under the little situation of motor profile variation, the mode that support and wheel hub are fixedly connected in the change prior art, the connecting mode of support and wheel hub changed at circumferencial direction locate by bulge loop, the axial location of motor is located in order to guarantee axiality by positioning spigot, gear in the rotating shaft connects transfer torque with the deceleration device of wheel hub, reaches conveniently the purpose of overhauling, save time, enhancing productivity and improving the non-maintaining cycle.
Description of drawings
Fig. 1 is the structural representation of the utility model large power, electrically driving wheel ac variable-frequency electric motor.
Embodiment
Main thought of the present utility model be solve exist in the prior art since motor bed-plate and locomotive wheel hub be designed to integrative-structure cause needing periodic inspection, dismounting trouble, spend a large amount of manpower and materials and useful life weak point problem, below embodiment is carried out detailed description, but not as to qualification of the present utility model.
As shown in Figure 1, the front and back end of support 6 is respectively equipped with front end housing 3 and rear end cap 7, and rotating shaft 1 is installed in front end housing 3 and the rear end cap 7 by shaft extension end bearing device 2 and the non-shaft stretching end bearing arrangement 8 that is arranged at its two ends.Rotor core 4 is rotating parts of motor, and its effect is to obtain rotating torque under the rotating magnetic field effect.The upper end of support 6 is provided with bulge loop 11a, the lower end is provided with bulge loop 11b, the outer peripheral face of bulge loop 11a and bulge loop 11b is respectively positioning spigot 10a and 10b, and two positioning spigots are used for locating flange, also is provided with the articulation hole 9 of the parallel axes of its axis and positioning spigot on the bulge loop 11b.Stator 5 connects with support 6, during motor mounting, utilize feasible mode that motor is delivered in the wheel hub, positioning spigot 10a on the support 6 and 10b are used to guarantee the alignment of motor and wheel hub, the articulation hole 9 that articulation bolt passes on the support 6 screws with wheel hub, fixes tightly by locating flange and wheel hub.Rotating shaft is provided with gear, the deceleration device of gear and the wheel hub transfer torque that is meshing with each other.
Certainly; the utility model can also have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.

Claims (3)

1. a motor comprises rotating shaft and support, it is characterized in that, the periphery of support upwards is provided with the positioning spigot that its axis overlaps with shaft axis at least.
2. motor according to claim 1 is characterized in that, an end of described support is provided with bulge loop, and the outer peripheral face of this bulge loop is described positioning spigot, also is provided with the articulation hole of the parallel axes of its axis and positioning spigot on bulge loop.
