Abstract
A kind of elevator differential gear set, by fixed teeth wheels, differential gear set, differential central siphon, differential bar head, steel ball forms, one end of differential bar is provided with differential bar head, the other end is provided with the ratch with drive motor gears meshing, differential bar head is arranged in differential central siphon, the tube wall of differential central siphon is provided with many group steel ball holes, and place steel ball, often organize the corresponding differential gear in steel ball hole, differential bar head is urged to differential gear by drive motor, differential bar head will ejection steel ball, steel ball is entered differential gear steel bead groove by ejection, differential central siphon and differential gear clamping, one group of differential gear set only has the differential gear just meeting transmission of clamping, other differential gear and differential central siphon only have idle running can not transmission.Power is exported by servo axis.After this differential gear set access elevator driving system, conveniently can regulate the transmission ratios between elevator and counterweight, make transmitting ratio adjustable.
Description
Technical field
The utility model belongs to lifting means field, and in particular, the utility model relates to a kind of elevator gear cluster.
Background technology
In current elevator, the radical function of traction system exports and transferring power, and elevator is run.Traction system is primarily of towing machine, traction steel-cable, and track adjusting wheel, rope sheave forms.Weight balancing system: the radical function of system is relative equilibrium car weight, and the weight difference between car and counterweight can be made in elevator work to remain within limit, ensures that the traction-driven of elevator is normal.System is primarily of counterweight and weight compensation means composition.In succession car and counterweight respectively in hoist ropes two ends, be wrapped in traction sheave and track adjusting wheel, hoisting motor by driving traction sheave to rotate after retarder speed change, by hoist ropes and the fricative tractive force of traction sheave, realize the dipping and heaving of car and counterweight, reach transport object.But the passage that the configuration of counterweight needs and elevator etc. are dark at present, clump weight and cab need isometric exercise, too much occupy space.
Utility model content
The utility model provides a kind of elevator device differential gear set realizing clump weight and cab and non-equally move, and this gear cluster can save clump weight running space and ratio is adjustable.
A kind of elevator differential gear set, by fixed teeth wheels, differential gear set, differential central siphon, differential bar head, steel ball forms, one end of differential bar is provided with differential bar head, the other end is provided with the ratch with drive motor gears meshing, differential bar head is arranged in differential central siphon, the tube wall of differential central siphon is provided with many group steel ball holes, and place steel ball, often organize the corresponding differential gear in steel ball hole, differential bar head is urged to differential gear by drive motor, differential bar head will ejection steel ball, steel ball is entered differential gear steel bead groove by ejection, differential central siphon and differential gear clamping, one group of differential gear set only has the differential gear just meeting transmission of clamping, other differential gear and differential central siphon only have idle running can not transmission.Power is exported by servo axis.
After this differential gear set access elevator driving system, conveniently can regulate the transmission ratios between elevator and counterweight, make transmitting ratio adjustable.

Detailed description of the invention
Below with reference to embodiment and accompanying drawing, stuctures and properties is described in further detail.
A kind of elevator differential gear set, by fixed teeth wheels 7, differential gear set 5, differential central siphon 10, differential bar head 9, steel ball 13 forms, one end of differential bar is provided with differential bar head 9, the other end is provided with the ratch 2 engaged with drive motor gear 3, differential bar head 9 is arranged in differential central siphon 10, the tube wall of differential central siphon 10 is provided with many group steel ball holes 4, and place steel ball 13, often organize the corresponding differential gear in steel ball hole 4, differential bar head 9 is urged to differential gear by drive motor 1, differential bar head 9 will ejection steel ball 13, steel ball 13 is entered differential gear steel bead groove 11 by ejection, differential central siphon 10 and differential gear clamping, one group of differential gear set only has the differential gear just meeting transmission of clamping, other differential gear and differential central siphon 10 only have idle running can not transmission.Power is exported by servo axis 6.After this differential gear set access elevator driving system, conveniently can regulate the transmission ratios between elevator and counterweight, make transmitting ratio adjustable.
It should be noted that, although above-mentioned explanation illustrate and describes some preferred embodiments of the present utility model, but as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
