Abstract
An electric winding machine with small teeth difference belongs to the technical field of machine manufacture. The utility model employs a speed reducer with small teeth difference to replace a usual gear speed reducer. The speed reducer with small teeth difference is composed of a casing, an inner gear, an eccentric shaft, a planetary gear and a planetary frame. A clutch is connected with the eccentric shaft of the speed reducer, the eccentric shaft is connected with the planetary gear which is meshed with the inner gear, and the planetary gear is connected with a drum via the planetary frame, the number of teeth of the planetary gear is one less than that of the inner gear. In working time, a motor drives the clutch which actuates the eccentric shaft of the speed reducer to rotate. Because the inner gear arranged in the speed reducer is fixed, the planetary gear is forced to wind around the inner gear to do planetary moving. Because the difference of the number of the gear between the planetary gear and the inner gear is one, the planetary gear reversely rotates through a tooth relative to the inner gear when a pivoted arm rotates a circle, and the reversely automatic rotating motion with low speed of the planetary is delivered to the drum via the planetary frame. The utility model employs the speed reducer with small teeth difference to realize single-stage driving, thereby the driving property of the utility model is reliable and stable, the driving efficiency is high and the durability is long.
Description
Technical field:
The utility model belongs to machinery manufacturing technology field, is a kind of winch.
Background technology:
Winch is main supporting with well cabinet frame or portal frame, is used for that building operation promotes material and vertical, level, the slope pulls and transports, and also can supportingly be used for piling with the Chinese toon construction machinery, towards grabbing work compound.Existing winch is made of electrical motor, coupler, retarder, reel, and wherein retarder adopts the multistage transmission of ordinary gear, and the transmission power consumption is bigger, and efficient is low, and fragile.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of driving efficiency height, the electric winch of long service life.
The technical solution of the utility model is to adopt few tooth differential retarder to replace common gear reducer, retarder is made of housing, inner gear, eccentric shaft, planetary wheel and pinion carrier, the eccentric shaft of coupler connection reducer, eccentric shaft connects planetary wheel, planetary wheel and internal gear teeth engagement, planetary wheel connects reel by pinion carrier, and the wherein planetary number of teeth is 39-43, the number of teeth of inner gear is 40-44, and the number of teeth of planetary ratio of number of teeth inner gear is lacked one.During work, the motor drives coupler, the eccentric shaft that coupler drives retarder rotates, because the inner gear in retarder maintains static, force planetary wheel around internal tooth crop rotation planet motion, promptly on the one hand around the revolution of inner gear center, do reverse rotation around himself axle center again on the other hand, because planetary wheel and inner gear number of teeth difference are one, so when pivoted arm turned over a week, planetary wheel oppositely turned over a tooth with respect to inner gear, is 41 with the planetary number of teeth, the number of teeth of inner gear is 42 calculating, when pivoted arm turned over 41 commentaries on classics with respect to inner gear, planetary wheel oppositely turned over a commentaries on classics with respect to inner gear, thereby realized that the reduction of speed ratio is 41: 1, the reverse low speed spinning motion of planetary wheel is passed to reel by pinion carrier, and reel twines or loosens rope belt animal material and promotes or decline.
The utility model adopts few tooth differential retarder one-level transmission, and the transmission power consumption penalty is little, so transmission performance is reliable, stable, and the driving efficiency height, overload performance is good, long service life, volume is little, in light weight, and is easy to maintenance.
Description of drawings:
Fig. 1 is the utility model scheme drawing;
Fig. 2 is the cutaway view of the utility model retarder part.
The specific embodiment:
The utility model is made of electrical motor 1, coupler 2, retarder 3, reel 4, wherein retarder 3 is few tooth differential retarder, constitute by housing 5, inner gear 6, eccentric shaft 7, planetary wheel 8 and pinion carrier 9, the eccentric shaft 7 of coupler 2 connection reducers 3, eccentric shaft 7 connects planetary wheel 8, planetary wheel 8 and the engagement of inner gear 6 teeth, planetary wheel 8 connects reel 4 by pinion carrier 9, wherein the number of teeth of planetary wheel 8 is 41, the number of teeth of inner gear 6 is 42, electrical motor 1 is 11KW, and model is Y160M-4B5, and module of gear is 5.5.In order to reduce the volume of the utility model electric winch, inner gear 6 in the retarder 3, eccentric shaft 7, planetary wheel 8 and pinion carrier 9 can be contained in reel 4 inside, the cylindrical shell of reel 4 replaces the housing 5 of retarder 3, simultaneously electrical motor 1 is become 7.5KW, model is Y132M-4B5, and module of gear is 4.5.
