Abstract
A kind of high pulling torque self-locking steering wheel is the utility model is related to, must have one group is the gear on worm and output shaft gear deceleration group of main transmission.It is characterized in that：The control circuit separated in closure by control board distinguishes connection angle sensor and motor, the main axis drive motor driving gear of motor, motor driving gear drives intermeshing worm screw connection gear therewith, worm screw connection gear and gear on worm are coaxial, gear on worm and output shaft gear are intermeshed and rotated together with driving, the axle of output shaft gear is connected with the angular transducer of bottom, angle sensor sensing carrys out the stalling of controlled motor to positional information and feeding back in control board after output shaft gear goes to certain angle, the travel position of output shaft gear and steering wheel above is connected to control with this, at this moment external force will produce revolution or uncontrolled if greater than the torsion of motor, so intermeshing worm screw connection gear just forms auto-lock function to output shaft gear therewith.
Description
Technical field
The present invention relates to a kind of steering wheel combined with circular gear with gear on worm, especially drives round tooth in gear on worm
Wheel increase moment of torsion, the steering wheel that the excessive circular gear of torque end load prevents from turning round and weight is lighter by gear on worm self-locking.
Background technology
Currently known steering wheel main Types have two kinds：One kind is electro-hydraulic actuator, i.e. motor driven liquid pressure equipment control flaps
Stroke, this steering wheel moment of torsion is big, and control is stable can to have suburb to prevent from turning round, and shortcoming is that weight is big, so being only used for ship mostly
Upper or ground installation.Another is that light-duty steering wheel is passed by seedless core motor, typical circular gear deceleration group, circuit board, angle
Sensor, shell are formed, although this steering wheel very light in weight, shortcoming is that torsion is small, can't prevent that moment end is firmly excessive
The revolution of generation.Done greatly overall, weight gets on again.Do not adapt to that some needs are in light weight, and high pulling torque and can is anti-rotation
Various application scenarios.
The content of the invention
In order to solve it is existing need it is in light weight, moment of torsion is big and and can effectively prevent moment end exert oneself it is excessive turn round it is each
Kind application scenarios.This real invention proposes a kind of new solution on the basis of existing light-duty steering wheel, constant in other structures
In the case of original typical circular gear deceleration group is changed to by circular gear to gear on worm in the circular gear to output shaft
Gear train, present principles are can to obtain big speed ratio by known gear on worm, and the characteristic of self-locking has been come during gear on worm active
Into.The big retarding ratio of gear on worm can also make original gear train reduce number, and weight further mitigates, and structure is more
Simply.Gear on worm, being linear contact lay between circular gear two-wheeled mesh tooth face, is promoted for spiral linear and is driven, therefore pass in transmission
Moment of torsion is bigger when dynamic.
The technical solution adopted for the present invention to solve the technical problems is：A kind of described high pulling torque self-locking steering wheel includes outer
Shell, control circuit, control board, angular transducer, motor, steering wheel, must have one group for main transmission gear on worm with it is defeated
Shaft gear deceleration group, other gear deceleration groups are one or more groups of；It is characterized in that described upper casing, middle shell, lower casing composition one
Individual closure, the control circuit separated in this shell by control board distinguish connection angle sensor and motor, electricity
The main axis drive motor driving gear of machine, motor driving gear drive intermeshing worm screw connection gear therewith, worm screw
Connection gear is coaxial with gear on worm, and gear on worm and output shaft gear are intermeshed and rotated together with driving, output shaft gear
Axle be connected with the angular transducer of bottom, angle sensor sensing is to position after output shaft gear goes to certain angle
Information simultaneously feeds back in control board the stalling for carrying out controlled motor, and output shaft gear and rudder above are connected to control with this
The travel position of disk, at this moment external force if greater than the torsion of motor will produce revolution or it is uncontrolled, then output shaft gear
Intermeshing worm screw connection gear just forms auto-lock function therewith.
The invention has the advantages that the steering wheel weight that Knucle-gear combines with gear on worm is lighter, moment of torsion is bigger, and can be right
Torque end load is excessive to prevent revolution from playing self-locking action.Suitable for lightweight robotic, Che Mo, model plane, flapping-wing aircraft, various flights
Device etc. needs the place of light-duty steering wheel.
Brief description of the drawings
Say that the present invention will be further described for example below in conjunction with the accompanying drawings.
Fig. 1 is steering wheel front view of the present invention.
Fig. 2 is steering wheel top view of the present invention.
1. upper casing in figure, shell in 2., 3 lower casings, 4. control boards, 5. control circuits, 6. angular transducers, 7. motor masters

Embodiment
It is steering wheel front view of the present invention in Fig. 1.The cavity of a closing is made up of upper casing (1), middle shell (2), lower casing (3)
Form a complete shell.Connection angle passes the control circuit (5) separated in this shell by control board (4) respectively
Sensor (6) and motor (12), the main axis of motor (12) drive the motor driving gear (7) of set thereon, motor driving gear
(7) drive intermeshing worm screw connection gear (11) therewith, worm screw connection gear (11) with gear on worm (9) coaxially, worm screw
Gear (9) is intermeshed and driven with output shaft gear (8) and rotates, the axle and angular transducer of output gear (8)
(6) it is connected, angular transducer (6) senses positional information and feeds back to control after output shaft gear (8) goes to certain angle
Carry out the stalling of controlled motor (12) in circuit board (4) processed, output shaft gear (8) and steering wheel above are connected to control with this
(10) travel position.Stopped when steering wheel (10) is moved to appropriate position, control to the rudder arm being connected to outside it is motionless after, at this moment
External force will produce revolution or uncontrolled if greater than the torsion of motor, then output shaft gear (8) is intermeshing therewith
Worm screw connection gear (11) just forms auto-lock function, and the accurate position for being just effectively controlled steering wheel (10) is not changing.
It is steering wheel top view of the present invention in fig. 2.The main axis of upper casing (1) interior motor (12), which drives, in figure covers thereon
Motor driving gear (7), motor driving gear (7) drive intermeshing worm screw connection gear (11) therewith, worm screw tooth connection
Take turns (11) and gear on worm (9) coaxially, gear on worm (9) is intermeshed and driven with output shaft gear (8) and rotates,
At this moment external force will produce revolution or uncontrolled if greater than the torsion of motor, then output shaft gear (8) is mutually nibbled therewith
The worm screw connection gear (11) of conjunction just forms auto-lock function.
