Description

Compact speed reduction driving device of hoisting block

[ technical field ] A method for producing a semiconductor device

The utility model relates to a compact speed reduction drive of hoist block is related to the improvement of the speed reduction drive of hoist block.

[ background of the invention ]

The existing common hoisting block is usually driven by manpower, the manual force acts on a wrench handle or drags the hand chain mechanism to rotate so as to drive a brake positioned in the body of the hoisting block, a long shaft is driven under the friction transmission of the brake, the rotation of the long shaft is transferred to a gear reduction mechanism to realize the low-speed rotation of a hoisting chain wheel, and finally, the intermittent ascending or descending action of a load is formed.

Because the existing hoisting block is only provided with a gear reduction mechanism at the tail end of the long shaft, and the input end of the long shaft is completely driven by manpower, the defects of small rotating speed reduction ratio and small transmission torque exist, so that the hoisting operation can be carried out by large manpower, the physical consumption of people is large, and the hoisting efficiency is low. If the pulling force is light or the dragging force is light, the diameter of the existing transmission gear train is usually increased, or a transmission wheel shaft speed reduction chain is added between a sheet tooth short shaft gear assembly and a spline hole gear of a gear speed reduction mechanism, so that the body of the hoisting block becomes very large, and the hoisting block cannot be operated in a narrow space.

[ Utility model ] content

The utility model aims at providing a compact speed reduction drive arrangement of hoist block, hoist block jack-up efficiency behind the configuration device is high, and can use manpower sparingly expenditure.

Therefore, the utility model provides a following technical scheme:

a compact speed reduction driving device of a hoist comprises a motor, an output gear arranged on an output shaft of the motor, a speed reduction box body, an input side planet carrier and an output side planet carrier, wherein the speed reduction box body is fixedly connected with a shell of the motor, a gear ring is arranged on the inner peripheral wall of the speed reduction box body, the output shaft, the input side planet carrier and the output side planet carrier are positioned on the same central line, a carrier gear and a sun gear are respectively fixed on two sides of the input side planet carrier, a planet wheel is fixed on one side of the output side planet carrier, end teeth are uniformly distributed on the other side of the output side planet carrier at intervals in the circumferential direction, the carrier gear is meshed with the output gear and the gear ring, and the planet wheel is meshed with the sun gear and the gear ring.

One of the sun gears is integral and one piece with the input planet carrier.

Because the sun gear and the planet carrier at the input side are single integral parts, the meshing precision of the sun gear and the planet gear is improved.

The utility model has the advantages of as follows and positive effect:

the output shaft, the input side planet carrier and the output side planet carrier of the motor are positioned on the same central line, and the carrier gear and the planet gear are meshed with the same gear ring together, so that not only is the meshing precision high, but also favorable conditions are created for the transverse (axial) size compactness of the speed reduction driving device;

one side of the planet carrier at the input side is used as driving input after being fixed with a carrier gear, and the end gear arranged at the other side of the planet carrier at the output side is used as driving output, so that the two planet carriers are combined into two-stage driving input and output double functions, the structure is compact and simple, the hoisting block provided with the device is suitable for operation in narrow space, the rotating speed reduction ratio is large, the transmission torque is large, and the advantages of saving manpower resources and efficiently operating are embodied.
