Description

A kind of one-way motors non-return mechanism

Technical field

The utility model relates to a kind of non-return mechanism, particularly relates to a kind of one-way motors non-return mechanism, belongs to machine field.

Background technology

At present, usually, in motor, non-return claw and two is taken turns bottom pillow block and is produced certain enclasping force, withstand with epitrochanterian bossing and play one direction effect, but due to synchronous machine moment comparatively large, in the process that non-return claw is returned, than being easier to jump on pawl pole plate, cause directed inefficacy.As at Chinese patent, application number: CN200510060580.4, patent name: a kind of built-in check device of Lundell synchronous motor, in that patent, disclose a kind of built-in check device of Lundell synchronous motor, comprise the rotor assembly of band pawl pole casing and band output shaft, rotor block is provided with in the middle part of output shaft, its overhanging end connects a rotor gear, rotor gear engages a non-return gear, the block wheel of non-return gear elastic fixing one with non-return block, casing is installed with a non-return gear shaft paralleled with output shaft, non-return gear, block wheel is coaxially slidably mounted on non-return gear shaft, the end face of non-return block touches mutually with the side of described rotor block, one overhanging projection face is set in the middle part of non-return gear, block wheel is symmetrically arranged with the elastic ring in " C " type of two evaginations, its internal diameter and the projection face of non-return gear are set to interference fit, advantage of the present invention is the direction operation function achieving Lundell synchronous motor.But in one-way motors, non-return claw and two is taken turns bottom pillow block and is produced certain enclasping force, withstands and plays one direction effect, in the process that non-return claw is returned, easily jump on pawl pole plate with epitrochanterian bossing, causes directed inefficacy.

Utility model content

Main purpose of the present utility model is to solve in process that above-mentioned one-way motors returns at non-return claw, easily jump on pawl pole plate, cause the directed problem lost efficacy, provide a kind of easy to assembly, structure simple, can effectively prevent non-return claw from jumping on pawl pole plate causes the directed a kind of one-way motors non-return mechanism lost efficacy.

The purpose of this utility model can reach by adopting following technical scheme:

A kind of one-way motors non-return mechanism, comprise pawl pole plate, rotor, pinion, some projections, non-return claw and two take turns, described rotor is arranged in pawl pole plate, described pinion is arranged at rotor center, described some projections are arranged at around pinion, and the central shaft of described non-return claw is arranged on the pawl pole plate of rotor edge, and described two take turns and to be arranged on non-return claw and central shaft overlaps with the central shaft of non-return claw, and two take turns and engage with pinion, described non-return claw lower end is provided with boss.

As a kind of preferred version, the height of described boss is greater than the thickness of non-return claw.

As a kind of preferred version, the shape of described boss is square or cuboid or cylinder or cone.

As a kind of preferred version, the material of described boss is identical with the material of non-return claw.

As a kind of preferred version, the number of described projection is 4.

Advantageous Effects of the present utility model:

The utility model is by the design to non-return claw convex platform, well solve in the process returned at non-return claw existed in prior art, non-return claw easily jumps on pawl pole plate, cause the problem that monophase machine orientation lost efficacy, to the design of non-return claw convex platform, when non-return claw is returned, the boss be arranged on non-return claw will push up the edge of pawl pole plate, effectively prevent non-return claw from jumping to pawl pole plate upper surface, cause directed inefficacy.

Embodiment

For make those skilled in the art clearly with clear and definite the technical solution of the utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.

As shown in Figure 1, Figure 2 and Figure 3, a kind of one-way motors non-return mechanism, comprise pawl pole plate 5, rotor 3, pinion 7, some projections 4, non-return claw 2 and two take turns 1, described rotor 3 is arranged in pawl pole plate 5, described pinion 7 is arranged at rotor 3 center, described some projections 4 are arranged at around pinion 7, the central shaft of described non-return claw 2 is arranged on the pawl pole plate 5 at rotor 3 edge, described two take turns 1 to be arranged on non-return claw 2 and central shaft overlaps with the central shaft of non-return claw 2, and two take turns 1 and engage with pinion 7, described non-return claw 2 lower end is provided with boss 6.

As shown in Figure 3 and Figure 4, as a kind of preferred version of the present embodiment, the height of described boss 6 is greater than the thickness of non-return claw 2, the shape of described boss 6 is square or cuboid or cylinder or cone, the material of described boss 6 is identical with the material of non-return claw 2, and the number of described projection 4 is 4.

In sum, the utility model is by the design to non-return claw convex platform, well solve in the process returned at non-return claw existed in prior art, non-return claw easily jumps on pawl pole plate, causes the problem that monophase machine orientation lost efficacy, to the design of non-return claw convex platform, when non-return claw is returned, the boss be arranged on non-return claw will push up the edge of pawl pole plate, effectively prevents non-return claw from jumping to pawl pole plate upper surface, causes directed inefficacy.

The above; be only the utility model patent preferred embodiment; but the protection range of the utility model patent is not limited thereto; anyly be familiar with those skilled in the art in the scope disclosed in the utility model patent; be equal to according to the technical scheme of the utility model patent and design thereof and replaced or change, all belonged to the protection range of the utility model patent.
