Abstract
The utility model discloses the speed adjusting gears on a kind of electric operator, wherein the worm screw including having spiral groove, and the worm gear in worm screw engagement.Sawtooth groove is provided on worm gear.The modulus of sawtooth groove is m=1.5 or m=2.0.The modulus of spiral groove is 4.71 or 6.28 pitches.The utility model has the effect of that increase is slowed down, volume becomes smaller and the replaceable different numbers of teeth.
Description
Technical field
The utility model relates to the speed adjusting gears on a kind of electric operator.
Background technique
Currently, electric operator is adjusted the speed using motor connection reduction gearing on the market.It is, speed is fast
When, reduction gearing is made very big, just realizes speed regulation.In this way, electric operator volume increases, difficult to install and cost increases
Add.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of increase slow down, volume become smaller with it is replaceable not
With the speed adjusting gear on the electric operator of the number of teeth.
To achieve the above object, the speed adjusting gear on a kind of electric operator provided by the utility model, wherein including
Worm screw with spiral groove, and the worm gear in worm screw engagement.Sawtooth groove is provided on worm gear.The modulus of sawtooth groove is m
=1.5 or m=2.0.The modulus of spiral groove is 4.71 or 6.28 pitches.
The utility model has the beneficial effects that having the effect of that increase is slowed down, volume becomes smaller and the replaceable different numbers of teeth.By
There is different module pitch in worm gear and worm screw, it is ensured that worm gear can output shaft moment promoted on a large scale, increase
Slowing effect.In addition, adjustment axle power can be by replacing worm gear and the worm screw of different moduluses away from size, it is not necessary to as existing skill
Art increases the mode of reduction gearing like that, therefore integrally-built volume can do very little, and worm gear and worm screw have intercommunity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model modulus is 1.5.
Fig. 2 is the structural schematic diagram that the utility model modulus is 2.
Specific embodiment
Utility model is described in further detail with reference to the accompanying drawing.
As shown in Figs. 1-2, the speed adjusting gear on a kind of electric operator, the worm screw 1 including having spiral groove 2, and
In the worm gear 3 that worm screw 1 engages.Sawtooth groove 4 is provided on worm gear 3.The modulus of sawtooth groove 4 is m=1.5 or m=2.0.Spiral shell
The modulus for revolving groove 2 is 4.71 or 6.28 pitches.
In application, worm gear 3 and worm screw 1 have different module pitch, it is ensured that worm gear 3 can output shaft moment obtain
It is a wide range of to be promoted, increase slowing effect.In addition, adjustment axle power can be by replacing worm gear 3 and the worm screw of different moduluses away from size
1, i.e., it can arrange in pairs or groups respectively multiple groups difference modulus with cabinet, it is not necessary to increase the mode of reduction gearing as the prior art, therefore whole
The volume of body structure can do very little, and worm gear 3 and worm screw 1 have intercommunity.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical new
The protection scope of type.
