Abstract
Originally practical to be related to a kind of anti-self-locking worm gear worm speed-down motor, including upper cover and pedestal, upper cover and pedestal are closed to form an accommodation space, motor, worm gear and worm screw are equipped in accommodation space, worm screw includes support shaft and a pair of rollback stop block for being located at end face circumference, anti- self-locking worm gear worm speed-down motor further includes connector, connector includes a pair of of spill spin block, it is arranged the perforation for protruding into worm screw after being fixedly connected with connector on motor output shaft, forms driving cooperation between the embeddable two rollback stop blocks of spill spin block.Since there are certain gaps between spill spin block and rollback stop block, when worm and gear occurs self-locking, the axial rotation motion of motor is stopped, and motor steering can slightly do reversed adjustment, so that worm and gear can continue to be able to gear reduction.The utility model has the advantages that structure is simple, at low cost.
Description
Technical field
The utility model relates to a kind of anti-self-locking worm gear worm speed-down motor.
Background technique
Worm and gear decelerator is widely used because of the big feature of reduction ratio.However, worm and gear subtracts
Electric motor with speed have the characteristics that it is self-locking, when the lead angle of worm screw be less than engagement wheel between cog equivalent friction angle when, worm and gear from
It locks, limits the transmission efficiency of worm and gear in certain degree, especially in the event of a power failure, worm and gear is easier to block
Extremely.Currently, structure is complicated for the tripper of worm and gear decelerator, it is at high cost.
Summary of the invention
In view of this, simply improving snail the purpose of this utility model is to provide a kind of spill spin block using on connector
The anti-self-locking worm gear worm speed-down motor of worm and gear latching characteristics.
In order to achieve the goal above, the utility model uses such a anti-self-locking worm gear worm speed-down motor, including
Upper cover and pedestal, the upper cover and the pedestal are closed to form an accommodation space, and electricity is equipped in the accommodation space
Machine, worm gear and worm screw, the worm screw include that support shaft and a pair of rollback stop block for being located at end face circumference, described preventing are self-locking
Worm and gear decelerator further includes connector, and the connector includes a pair of of spill spin block, is arranged on motor output shaft solid
The perforation of worm screw is protruded into after the fixed connection connector, is formed and is driven between the embeddable two rollback stop blocks of the spill spin block
Dynamic cooperation.Compared with prior art, the advantageous effects of the invention are: design through the above structure, due to rotation
There are certain gaps between switch block and rollback stop block, when worm and gear occurs self-locking, the axial rotation motion of motor
Stopped, motor steering can slightly do reversed adjustment, so that worm and gear can continue to be able to gear reduction.The utility model tool
Have the advantages that structure is simple, at low cost.
Particularly, the pedestal is equipped with bearing caulking groove, is embedded in bearing, the support shaft in the bearing caulking groove
Across the bearing, retaining sheet is protruded into.Design through the above structure, so that worm screw can rotate in retaining sheet, friction system
Number is low, substantially increases the transmission efficiency of worm and gear.
Particularly, pressure sets a rubber pad between the upper cover and the pedestal.Design through the above structure, prevents
External dust is fallen between the gear teeth of worm and gear, ensure that the transmission efficiency of worm and gear.
Detailed description of the invention
Fig. 1 is that the utility model embodiment removes the structural schematic diagram after upper cover；
Fig. 2 is the structural schematic diagram of spill spin block in the utility model embodiment；
Fig. 3 is the structural schematic diagram of worm screw in the utility model embodiment.

Specific embodiment
As shown in Figure 1, 2, 3, a kind of anti-self-locking worm gear worm speed-down motor, including upper cover and pedestal 2, upper cover and pedestal
2 closures form an accommodation space, and motor 3, worm gear 8 and worm screw 7 are equipped in accommodation space, and worm screw 7 includes support shaft 71 and one
To the rollback stop block 72 for being located at end face circumference, anti-self-locking worm gear worm speed-down motor further includes connector 4, and connector 4 wraps
A pair of of spill spin block 42 is included, the perforation 73 for protruding into worm screw 7 after being fixedly connected with connector 4, spill spin block 42 are arranged on motor output shaft 31
Driving cooperation is formed between embeddable two rollback stop blocks 72.
Pedestal 2 is equipped with bearing caulking groove, and bearing 6 is embedded in bearing caulking groove, and support shaft 71 passes through bearing 6, protrudes into retaining sheet
5。
Pressure sets a rubber pad 9 between upper cover and pedestal 2.
