Description
Technical field
The utility model relates to electronic worm and gear technical fields, in particular to a kind of in electronic worm and gear assembly
Motor adjust support construction.
Background technique
Referring to Fig. 1 and Fig. 2, electronic worm and gear assembly includes motor assembly 10 and worm reduction box assembly at present
20, motor assembly 10 is mounted on the deceleration box 21 of worm reduction box assembly 20, the armature shaft 11 in motor assembly 10
It is inserted into deceleration box 21, worm screw 12 is molded directly on armature shaft 11, and the worm gear 40 engaged with worm screw 12, which is also disposed at, to be subtracted
In fast cabinet 21.Existing motor adjusts the small axis 13 of support that supporting mechanism is 11 end of armature shaft and is spun on deceleration box by one
Adjusting nut 30 on 21 supports.Supporting small axis 13 is cylindrical shaft, and the supported hole 31 in adjusting nut 30 is cylindrical hole, is supported small
Axis 13 is inserted into supported hole 31.Such motor adjusts support construction, and there are the following problems: adjusting nut cannot be effectively ensured
To supporting small axis 13 to be supported, it be easy to cause 12 stress of worm screw to be bent, causes worm screw 12 to engage with worm gear 40 incorrect, so that
Transmission efficiency reduces, and friction loss increases, and noise increases, service life reduction.
Utility model content
The technical problem to be solved by the utility model is to for the motor adjusting in existing electronic worm and gear assembly
Above-mentioned technical problem present in support construction and a kind of use that can be remained and effectively be supported to armature shaft end is provided
Motor in electronic worm and gear assembly adjusts support construction.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of motor adjusting support construction in electronic worm and gear assembly, including motor assembly and worm and gear subtract
Fast box assembly, the motor assembly is mounted on the deceleration box of the worm reduction box assembly, in the motor assembly
Armature shaft be inserted into the deceleration box, worm screw is molded directly on the armature shaft, the worm gear engaged with the worm screw
It is also disposed in deceleration box；The armature shaft terminal position is corresponded in the deceleration box and offers a threaded hole, described
Threaded hole is internally screwed with an adjusting nut；It is characterized in that, a taper support axis is provided in the armature the tip of the axis, described
Taper support hole is provided in adjusting nut, the taper support axis is inserted into the taper support hole, so that adjusting nut
The taper support axis is supported by taper support hole, and then the armature the tip of the axis is supported.
In a preferred embodiment of the utility model, the cone angle of the taper support axis and the taper support hole
Cone angle is 10~60 °.
In a preferred embodiment of the utility model, in armature shaft described in the center axis deviation of the threaded hole
0.2~0.3mm of mandrel line.
Due to use technical solution as above, the utility model compared with prior art, the central axis of threaded hole
Deviate 0.2~0.3mm of central axis of the armature shaft, while adjusting nut passes through taper support hole to the taper support axis
It is supported, and then the armature the tip of the axis is supported, adjusting nut is remained to armature shaft end branch
Support, so that the bending of worm screw stress is small, worm screw engagement transmission efficiency reduction is small, and friction loss is reduced, under noise increasing degree
Drop, service life increase.

Fig. 1 is the structural schematic diagram of existing electronic worm and gear assembly.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the deceleration box structural schematic diagram of the utility model.
Fig. 4 is the armature structure schematic diagram of the utility model.
Fig. 5 is the adjusting nut structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the drawings and specific embodiments.
Referring to fig. 2 to Fig. 5, a kind of motor in electronic worm and gear assembly shown in figure adjusts support construction,
Including motor assembly 100 and worm reduction box assembly 200, motor assembly 100 is mounted on worm reduction box assembly 200
Deceleration box 210 on, the armature shaft 110 in motor assembly 100 is inserted into deceleration box 210, and worm screw 120 is molded directly within
On armature shaft 110, the worm gear 400 engaged with worm screw 120 is also disposed in deceleration box 210.
A threaded hole 211 is offered in corresponding 110 terminal position of armature shaft of deceleration box 210, in threaded hole 211
The distance that mandrel line 211a deviates the central axis 111 of armature shaft 110 is 0.2~0.3mm.
It is internally screwed with an adjusting nut 300 in threaded hole 211, taper support hole 310 is provided in adjusting nut 300, is bored
The cone angle of shape supported hole 310 is 10~60 °.
In addition the end of armature shaft 110 is provided with a taper support axis 130, the cone angle of taper support axis 130 is also 10
~60 °.
Taper support axis 130 is inserted into taper support hole 310, so that adjusting nut 300 is right by taper support hole 310
Taper support axis 130 is supported, and then is supported to the end of armature shaft 110.
By using above-mentioned technical proposal, adjusting nut 300 is remained to 110 end support of armature shaft, into
And making the bending of 120 stress of worm screw small, worm screw 120, which engages transmission efficiency, reduces small, friction loss reduction, noise increasing degree
Under, service life reduction is small.
