Abstract
The invention relates to a mechanical grouped worm and worm gear transmission device. The mechanical grouped worm and worm gear transmission device is characterized in that by the aid of a left differential half shaft (3) and a right differential half shaft (4) which output freedom degree rotationally, power of a rotary power input shaft (1) drives a left worm (9) through a left differential half-shaft bevel gear (5), a left worm transmission bevel gear (7) and drives a right worm (10) through a right differential half-shaft bevel gear (6) and a right worm transmission bevel gear (8), the left worm (9) and the right worm (10) are arranged around the same worm gear (11) and are meshed with the same unidirectionally, and the worm gear (11) is mounted on a worm gear central shaft (12). The mechanical grouped worm and worm gear transmission device is large in transmission ratio, can improve power or transmission capability of torque and is mainly applicable to all conditions requiring to stop reverse rotation and particularly applicable to running machinery or lifting machinery.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate in particular to the device that mechanical type crowd worm screw is rotated to worm drive.
Background technique
Worm gearing has good reliability, but possesses the characteristic of self-locking, has extremely low reverse transmission efficiency; Velocity ratio is bigger; Characteristics such as transmitting torque is bigger have unique function in mechanical transmission, can not be substituted by other type of belt drive; It is high-power that but worm and gear can not transmit based on the mesh form of worm gear and worm screw, and the moment of transmission also far can not reach the bigger moment that worm gear can carry.
Summary of the invention
In order to address the above problem, the objective of the invention is for having realized more high-power and transmission moment
And the formula crowd Worm and Worm Gear Driving device that designs a mechanism, this device is through a pair of or several to worm screw, drives one or several worm gear simultaneously, has kept the fundamental characteristics of worm and gear transmission, has widened the application of worm and gear transmission.The technological scheme that the present invention taked is: two semiaxis that rotate the output degrees of freedom of the power utilization differential mechanism of rotating power input shaft are driven a pair of worm screw through umbrella gear; This is located at same worm gear periphery to worm screw and meshes in the same way with worm gear, and worm gear is installed on the worm gear central shaft.In addition, can take a plurality of worm gears coaxial, each worm gear can carry the transmission capacity that a pair of worm screw mode further adds high-power or moment of torsion.
It is big that the present invention has transmission ratios, adds the transmission capacity of high-power or moment of torsion, and predominant use can be used for preventing all operating modes of reversing drive, is specially adapted to running mechanism or elevation and subsidence mechanical.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure, 1, the rotating power input shaft, 2, differential mechanism, 3, the differential left semiaxis; 4, differential mechanism right axle shaft, 5, differential left semiaxis umbrella gear, 6, differential mechanism right axle shaft umbrella gear; 7, left side worm drive umbrella gear, 8, right side worm drive umbrella gear, 9, the left side worm screw; 10, right side worm screw, 11, worm gear, 12, the worm gear central shaft.
Embodiment
With reference to accompanying drawing; The technological scheme that the present invention taked is: worm screw 9 and right side worm screw 10 a pair of worm screws on the left of the differential left semiaxis 3 that two of the power utilization differential mechanism 2 of rotating power input shaft 1 are rotated the output degrees of freedom drive respectively through differential left semiaxis umbrella gear 5, left side worm drive umbrella gear 7 and differential mechanism right axle shaft umbrella gear 6, right side worm drive umbrella gear 8 respectively with differential mechanism right axle shafts 4; Left side worm screw 9 is located at same worm gear 11 peripheries with right side worm screw 10 and meshes in the same way with worm gear 11, and worm gear 11 is installed on the worm gear central shaft 12.In addition, can take a plurality of worm gears coaxial, each worm gear can carry the transmission capacity that a pair of worm screw mode further adds high-power or moment of torsion.
Working principle of the present invention is following:
Common worm and gear transmission is single worm gear engagement driving moment of single worm screw and rotation; Can be when many worm screws drive same worm gear because the tooth of the tooth that reasons such as manufacture deviation, installation deviation, back lash, transmission phase difference cause each worm screw and worm gear does not mesh simultaneously; Even cause few part worm drive worm gear; Many parts worm screw is through self-locking effect locking worm gear, causes each worm screw driven in common worm gear but problems such as phase mutual interference simultaneously.The present invention through differential mechanism decompose rotate be two moments of torsion in the same way, can nonsynchronously rotate; Let two of differential mechanism to export the rotation that rotational freedoms are regulated each worm screw, guarantee that each worm movement direction is identical with movement tendency, guarantee common engagement of each worm and wheel and rotation simultaneously; Realized that so same worm gear periphery has two place worm screws to be engaged with and transferring power; Increase the moment and the power of worm and gear transmission, reduced the anti-pass efficiency of movement to a greater extent simultaneously, increased the self-locking stall torque; Balance has also been cancelled the unbalanced force on the worm-wheel shaft, has realized torque of couple transmission rotation.
Principle of the present invention is: driving moment is through rotating power input shaft 1; Be delivered to differential mechanism 2; Rotational power is decomposed into the rotational freedom of two interdependences by differential left semiaxis 3 and 4 outputs of differential mechanism right axle shaft; Since differential left semiaxis umbrella gear 5 and differential left semiaxis 3 coenosarcs, differential mechanism right axle shaft umbrella gear 6 and differential mechanism right axle shaft 4 coenosarcs, differential left semiaxis umbrella gear 5 and 7 engagements of left side worm drive umbrella gear; Differential mechanism right axle shaft umbrella gear 6 and 8 engagements of right side worm drive umbrella gear; Left side worm drive umbrella gear 7 and left side worm screw 9 coenosarcs, right side worm drive umbrella gear 8 and right side worm screw 10 coenosarcs are so two interdependent each other rotations of having decomposed have been directly delivered to left side worm screw 9 and right side worm screw 10; Left side worm screw 9 meshes with worm gear 11 with right side worm screw 10 simultaneously, and worm gear 11 rotates around worm-wheel shaft 12 under the driving of left side worm screw 9 and right side worm screw 10.The rotation of left side worm screw 9 and right side worm screw 10 is from same differential mechanism 2; So two rotations have common sense of rotation, common rotation trend; The big or small interdependence of moment of rotation; Be formed on the worm screw of rotating under the common worm gear constraint in advance and being obstructed and can wait for the worm screw of subsequent rotation underloading, two worm screws like this can be realized promoting jointly worm gear 11 and rotated around worm-wheel shaft 12.When back drive condition occurring; Reversing drive equally can be because each worm screw positive engagement previous the time; And possesses good while repercussion meshing condition; Realize group operating mode of worm screw self-locking worm gear or the worm gear operating mode to crowd worm screw reversing drive, so transmission system can be born bigger self-locking ultimate load.
