Abstract
The utility model discloses a kind of double rack transmission speed growth mechanism, slide unit is located at the surface of pedestal, and carry-over bar is fixedly connected with slide unit, and fixed rack is fixedly connected with pedestal；One end of pinion stand connects cylinder piston rod, other end assembling gear, and gear engages simultaneously with carry-over bar, fixed rack；Pedestal is equipped with two slide unit sliding rails, and the slide unit sliding rail that slides through of slide unit on the base is oriented to, and buffer is slide unit limiting buffer；Design has pinion stand sliding rail between pinion stand and pedestal；The side of pedestal is equipped with inductive switch.
Description
Technical field
The utility model relates to field of automobile more particularly to a kind of double rack transmission speed growth mechanisms.
Background technique
Rack and pinion drive mechanism generally comprises a gear and a toothed rack two parts.Motor driven gear wheel rotation, tooth
Opposed gear makees linear relative movement.It is the movement that a kind of traditional rotation straightens line.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and provide a kind of double rack transmission increasing
Fast mechanism, improves transmission speed, is 2 times of single rack geared speed.
To achieve the goals above, the utility model adopts the technical scheme that a kind of double rack transmission speed growth mechanism,
Including slide unit (1), pedestal (2), carry-over bar (3), gear (4), fixed rack (5), cylinder (6), pinion stand (7), pinion stand sliding rail
(8), slide unit sliding rail (9), buffer (10), inductive switch (11)；
The slide unit (1) is located at the surface of pedestal (2), and the carry-over bar (3) is fixedly connected with slide unit (1), described fixed
Rack gear (5) is fixedly connected with pedestal (2)；One end connection cylinder piston rod of the pinion stand (7), other end assembling gear (4),
The gear (4) is engaged simultaneously with carry-over bar (3), fixed rack (5)；Pedestal (2) is equipped with two slide unit sliding rails (9), the cunning
Platform (1) slides through slide unit sliding rail (9) guiding on pedestal (2), and buffer (10) is slide unit limiting buffer；The pinion stand
(7) there are pinion stand sliding rail (8) described in design between the pedestal (2)；The side of the pedestal (2) is equipped with the inductive switch
(11)。
The utility model has the beneficial effects that the present apparatus passes through engaged transmission between gear and double rack, gear may be implemented
The function of carry-over bar movement is pushed, meanwhile, cylinder (or oil cylinder or screw-nut) is pushed by air pressure (oil pressure, electronic, manual)
Gear movement improves work efficiency to realize the double speed movement of slide unit, and utility model design is reasonable.To realize high speed
The operating condition of movement provides optinal plan.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of double rack transmission speed growth mechanism structural schematic diagram.
Fig. 2 be the utility model proposes a kind of double rack transmission speed growth mechanism working principle diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of double rack transmission speed growth mechanism, including slide unit 1, pedestal 2, carry-over bar 3, gear 4, fixed rack
5, cylinder 6, pinion stand 7, pinion stand sliding rail 8, slide unit sliding rail 9, buffer 10, inductive switch 11.
The slide unit 1 is located at the surface of pedestal 2, and the carry-over bar 3 is fixedly connected with slide unit 1, the fixed rack 5 and base
Seat 2 is fixedly connected.The piston rod of one end connection cylinder 6 of the pinion stand 7, other end assembling gear 4, the gear 4 with it is dynamic
Rack gear 3, fixed rack 5 engage simultaneously.Pedestal 2 be equipped with two slide unit sliding rails 9, the slide unit 1 on the base 2 slide through cunning
Platform sliding rail 9 is oriented to, and buffer 10 is slide unit limiting buffer.For the smooth motion for guaranteeing gear 4, set between pinion stand 7 and pedestal 2
In respect of sliding rail 8.The side of pedestal 2 is equipped with inductive switch 11.
Working principle: when work, as shown in Fig. 2, cylinder 6 pushes gear 4 to move, while gear 4 is engaged with rack gear (3,5)
Transmission, carry-over bar drive slide unit 1 mobile.
If cylinder stroke 500mm, gear 500mm forward is pushed, simultaneously because the engaged transmission of wheel and rack, drives and slide
Platform has just moved forward 1000mm.I.e. in the same time, piston rod pushes the mobile 500mm of gear, and terminal slide unit moves
1000mm is 2 times of cylinder stroke.
Moving parts slide unit speed is 2 times of traditional single transmission speed.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
