Abstract
A novel efficient small size hoister comprises a machine shell (1), a cranking bar (4), a less tooth number difference transmission device (14), which consists of an internal gear circle (7), a tooth wheel (8), a fixed axle (9), a shaft (10) and a crank (11), wherein the internal gear circle (7) is fixed on the machine shell (1), the fixed axle (9) is arranged in the center of the internal gear circle, the shaft (10) is arranged in the center of the tooth wheel (8), the cranking bar is arranged in one end of the fixed axle, one end of the crank is fixed on the fixed axle, the other end is fixed on the shaft, the tooth wheel (8) is arranged inside the internal gear circle and meshed with the internal gear circle. The utility model solves problems of low transmission efficiency and big volume of gear side transmission hoister in a worm gear hoister and uses less tooth number difference transmission principle to realize big deceleration ratio transmission, the utility model has the advantages of compact whole structure, high efficient transmission, low weight, low noise and big traction force.
Description
Technical field: the utility model is the improvement product of existing winch.
Background technology: the winch of using on the engineering adopts worm and gear or gear pair transmission to realize the big retarding ratio mostly at present, its shortcoming is that the driving efficiency of Worm-gear type winch is low, and the transmission original paper of gear pair driving type winch is many, the whole transmission device volume is big, from great, and the manufacturing cost height.
Summary of the invention: the utility model is that the driving efficiency at the worm and gear winch is low, gear pair transmission winch structure heaviness, bulky shortcoming, studies a kind of new and effective small size winch with few tooth difference transmission simple in structure, compact, that volume is little, transmitting ratio is high and tractive force is big.The utility model includes casing 1, rocking handle 4, gearing with small teeth differenc 14, gearing with small teeth differenc 14 is made up of internally toothed annulus 7, gear 8, anchor shaft 9, axis of revolution 10, crank 11, internally toothed annulus 7 is fixed on the casing 1, anchor shaft 9 is arranged on the center of internally toothed annulus 7, axis of revolution 10 is arranged on the center of gear 8; rocking handle 4 is arranged on an end of anchor shaft 9; end of crank 11 is fixed on the anchor shaft 9; other end of crank 11 is fixed on the axis of revolution 10; gear 8 is arranged in the internally toothed annulus 7, and meshes with internally toothed annulus 7.The worm and gear driving efficiency that the utility model has solved winch is low, the bulky problem of gear pair transmission winch, the few tooth difference transmission principle of the utility model utilization realizes that big retarding compares transmission, have single unit system compact conformation, driving efficiency height, can reach more than 95%, and advantage in light weight, that noise is low and tractive force is big.
Description of drawings: Fig. 1 is a three-dimensional structure diagram of the present utility model, and Fig. 2 is the structural representation of the specific embodiment.
The specific embodiment: present embodiment is made up of casing 1, steel rope 2, handle 3, rocking handle 4, position pin 5, non-return hook 6, gearing with small teeth differenc 14, needle bearing 12, needle bearing 13.Gearing with small teeth differenc 14 is made up of internally toothed annulus 7, gear 8, anchor shaft 9, axis of revolution 10, crank 11, internally toothed annulus 7 is fixed on the casing 1, anchor shaft 9 is arranged on the center of internally toothed annulus 7, axis of revolution 10 is arranged on the center of gear 8; rocking handle 4 is arranged on an end of anchor shaft 9, and an end of crank 11 is fixed on the anchor shaft 9, and the other end of crank 11 is fixed on the axis of revolution 10; gear 8 is arranged in the internally toothed annulus 7, and meshes with internally toothed annulus 7.Steel rope 2 is wrapped in and is fixed on two wheel hub 8-1 between the identical gear 8, power applies moment by 4 pairs of anchor shafts 9 of rocking handle, by means of crank 11 gear 8 is rotated along the inner ring of internally toothed annulus 7, returning wheel shaft 10 is rotation centers of gear 8, rotate around anchor shaft 9 with rocking handle 4 simultaneously, the number of teeth of internally toothed annulus 7 is Z
7, the number of teeth of gear 8 is Z
