Abstract

Disclosed in the utility model is a motor with a detachable bearing fixing apparatus. The motor comprises a housing; and one end of the housing is provided with a detachable bearing support for fixing a bearing. The motor has the following advantages: the bearing fixing apparatus can be disassembled easily and thus can be used conveniently; the bearing can be fixed and dropping out of the rotor can be effectively prevented; and compared with the existing metal end cover, the bearing fixing apparatus has the smaller size, lighter weight, and lower cost and can be manufactured easily.

Description

The dismountable motor of a kind of bearing fixing device

Technical field

The utility model relates to a kind of motor, relates in particular to a kind of motor with detachable bearing fixture.

Background technology

The motor of existing manufacturer production is generally used metal end rigid bearing, good airproof performance like this, bearing is difficult for loosening, but while installing and using, in order to reduce the noise of machine, guarantee motor and other machines flange components concentricity no-float, generally to remove this metal end, so not only wasted metal material, improved cost, and metal end and bearing adopt interference fit or interference fits substantially, so dismounting is difficult for, operation inconvenience.If motor does not arrange the device of rigid bearing, obviously more unfavorable, not only easily cause the loosening of bearing or damage, even the rotor in motor also can drop in transportation road, causes motor to damage.

Utility model content

Utility model object: the purpose of this utility model is to provide a kind of motor that can bearing fixing device for convenience detach.

Technical scheme: the dismountable motor of a kind of bearing fixing device described in the utility model, comprise housing, in one end of housing, be provided with for rigid bearing, dismountable support of bearing.

Wherein, the described support of bearing comprises the dead eye for rigid bearing, and the periphery in this hole extends to the inner wall of end of housing and by bolt, the support of bearing is fixed on motor.Described dead eye extends to the inner wall of end of housing by two arms of symmetry.On described motor, open the hole of running through housing, bolt is fixed by this hole and the support of bearing.Some bearing stop blocks that extend internally are set on described dead eye.

Beneficial effect: the utility model compared with prior art, easily dismantle, easy to use by the device that its advantage is held for this motor fixing shaft; In rigid bearing, effectively prevent that rotor from dropping out; Compare with original metal end, its volume reduces, and weight saving reduces costs, and easily manufactures.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the exploded view of the utility model motor and the support of bearing;

Fig. 3 is the upward view of the utility model support of bearing;

Fig. 4 is the vertical view of the utility model support of bearing.

Embodiment

As Figure 1-4, this motor comprises cylindrical housings 1, is furnished with bearing 2, stator and rotor in housing 1.In housing 1 one end, the support of bearing 3 is set, the center of this support of bearing 3 is that columniform dead eye 4(is shown in Fig. 3 and Fig. 4), the slightly larger in diameter of dead eye 4 is in the external diameter of bearing 2, dead eye 4 has certain altitude, so the support of bearing 3 can entangle and rigid bearing 2 on, from dead eye 4 bilateral symmetry, two arms 5 are set, arm 5 stretches out and touches the inwall of housing 1, so two arms 5 are just in time slightly less than the internal diameter of housing 1 in conjunction with the distance of dead eye 4, screw 6 is respectively opened in two outer ends at arm 5, in the position that housing 1 is corresponding with screw 6, also open two holes 7, hole 7 axially arranges, run through housing 1, then bolt 8 stretches into from the hole 7 of housing 1 other end, the support of bearing 3 is enclosed within on bearing 2, bolt 8 puts in screw 6 simultaneously and tightens with it fixing, now the support of bearing 3 firmly can be fixed on bearing 2.Certainly, in order further to fix bearing, to prevent that rotor from dropping out, at two bearing stop blocks 9 of arranged outside of dead eye 4, bearing stop block 9 is towards the interior extension of dead eye 4.
