Abstract
The invention discloses a high-thrust linear movement device which comprises a motor and a screw rod mechanism, wherein a turbine worm mechanism and a conical gear mechanism which are engaged with each other are arranged between the motor and the screw rod mechanism. The invention provides a high-thrust linear movement device with small structural dimension and high thrust.
Description
Technical field
The present invention relates to a kind of linear motion device, relate in particular to a kind of high-thrust linear movement device.
Background technique
Traditional rotatablely moving is converted to straight-line mode and adopts pinion and rack more, the wheel and rack engagement, rotatablely moving of electric-motor-driving transferred to the thrust that produces rectilinear direction behind the straight line motion, if but the linear thrust that requires is when big, then the physical dimension of whole device will be very big, and large-sized linear motion device can't be applied in some narrow environments or the less environment.
Summary of the invention
The technical problem to be solved in the present invention is, in prior art, for the application of ask for something high thrust, the size of existing linear motion device is bigger, can't be applied in the defective of this occasion, the high-thrust linear movement device that a kind of physical dimension is less, thrust is big is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-thrust linear movement device, comprise motor, screw mechanism, and between motor and screw mechanism, be provided with intermeshing turbine and worm mechanism and umbrella gear mechanism.
Described turbine and worm mechanism comprises intermeshing worm screw and turbine, worm screw and turbine is enclosed the housing that covers, and wherein worm screw is connected with motor transmission shaft, and turbine is connected with umbrella gear mechanism.
The velocity ratio i of described worm screw and turbine is 1: 50～60.
Described turbine and worm mechanism below is provided with the supporting frame that is used to support turbine and worm mechanism.
Described umbrella gear mechanism comprises two intermeshing first umbrella gear and second umbrella gear, and wherein first umbrella gear is connected with turbine and worm mechanism, and second umbrella gear is connected with screw mechanism.
Described first umbrella gear is to be connected with the turbine center by rotating shaft.
Shaft angle between first umbrella gear and second umbrella gear is 90 °.
First umbrella gear and second umbrella gear are provided with the fixed cover of an end opening outward, the fixed cover sidewall has through hole, rotating shaft is passed through hole and is connected with first umbrella gear, and the opening end of fixed cover is sleeved on the end of screw mechanism, and second umbrella gear is fixedlyed connected with the leading screw in the screw mechanism.
The present invention adopts the transmission of turbine and worm deceleration and umbrella gear, has increased the power of transmitting, and will rotatablely move by screw mandrel transfers straight line motion to again.Device of the present invention is compact structure not only, and volume is little, is suitable in the less environment, and is convenient to realize automatic control.Though use the wattage of motor very little, it is very big to produce the power that promotes.Promote really to have realized high load with small power than own big several times object.
