Abstract
The utility model discloses a worm planetary reducer used for an automobile motor-driven tread plate machine. The worm planetary reducer used for the automobile motor-driven tread plate machine comprises a sun gear (2), an output planet carrier (3), a planet gear (4), a reduction box body (6), a worm gear (6), a bumper block (7), a worm cover board (8) and a worm motor (10); the worm gear (6) is connected with the sun gear (2) through the bumper block (7) and the worm cover board (8); the bumper block (7) is in contact with reinforcing ribs inside the worm gear (6); and the bumper block (7) is in contact with the worm cover board (8) through protrusion parts on the worm cover board (8). According to the worm planetary reducer used for the automobile motor-driven tread plate machine, a worm and gear structure is combined with the planet gear structure, the worm gear is connected with the planet gear structure through the bumper block, structure is compact, gear ratio is big, and inverse motion is self-locking.
Description
Technical field
The utility model relates to a kind of worm planet speed reducer, relates to particularly a kind of worm planet speed reducer for the motorcar electric pedal exerciser.
Background technique
In the prior art, the planetary speed reducer structure that is used for the motorcar electric pedal exerciser is huger, be unfavorable for the saving of inner space of vehicle, and reduction speed ratio is little, does not have auto-lock function, produces easily reversing motion, is producing on the run potential safety hazard.
The model utility content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of worm planet speed reducer for the motorcar electric pedal exerciser, comprise sun gear, output planetary frame, planet wheel, deceleration box, worm gear, buffer stopper, worm gear cover plate, to be connected with the worm gear cover plate by buffer stopper between the endless screw electric motor, described worm gear and sun gear.
Further, described buffer stopper contacts with the reinforced rib of worm gear inside.
Further, contact by the bump on the described worm gear cover plate between described buffer stopper and the worm gear cover plate.
Further, the number of described bump is three.
Further, connect by profile between described worm gear cover plate and the sun gear.
Further, also comprise the output planetary frame, the involute internal tooth in described sun gear, the deceleration box and planet wheel and output planetary frame consist of planetary gears together.
Worm planet speed reducer for the motorcar electric pedal exerciser of the present utility model makes up by worm gear structure and planetary gear structure, adopts buffer stopper to connect between worm gear and the planetary gear structure, compact structure, and gear ratio is large, to the backward motion self-locking.
Description of drawings
Fig. 1 is the structural representation of the worm planet speed reducer for the motorcar electric pedal exerciser of the present utility model;
Fig. 2 is the exploded view that is used for the worm planet speed reducer of motorcar electric pedal exerciser shown in Figure 1.
Embodiment
As illustrated in fig. 1 and 2, worm planet speed reducer for the motorcar electric pedal exerciser of the present utility model, it combines worm gear and planetary speed reducer, does the decelerating through motor transmission, main feature is to adopt buffer stopper to connect between worm gear and the planetary speed reducer, rather than directly is rigidly connected.
The utility model mainly comprises following structure: case lid 1, sun gear 2, output planetary frame 3, planet wheel 4, deceleration box 5, worm gear 6, buffer stopper 7, worm gear cover plate 8, worm gear lid 9 and endless screw electric motor 10.
Endless screw electric motor 10 is exported rotational motion by worm screw 10-1, the worm gear 6 of drive and worm screw 10-1 engagement rotates, buffer stopper 7 is laid in worm gear 6 inside, reinforced rib on buffer stopper 7 and worm gear 6 inside engages and drives 8 rotations of worm gear cover plate, three cylindrical body power transmissions by protruding on the worm gear cover plate 8 between buffer stopper 7 and the worm gear cover plate 8.
Connect by profile between worm gear cover plate 8 and the sun gear 2, power transmission is arrived sun gear 2, involute internal tooth in sun gear 2, the deceleration box 5 and planet wheel 4 and output planetary frame 3 consist of planetary gears together, thereby make power through 3 outputs of output planetary frame.
Worm planet speed reducer for the motorcar electric pedal exerciser of the present utility model makes up by worm gear structure and planetary gear structure, adopts buffer stopper to connect between worm gear and the planetary gear structure, compact structure, and gear ratio is large, to the backward motion self-locking.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
