Abstract
A three-input hoisting speed reducer comprises a casing, a body and a brake. Both the body and the brake are connected with the casing through bolts. The three-input hoisting speed reducer is characterized in that three identical input shafts are fixed on the casing through tapered roller bearings and are fixed on the body through other tapered roller bearings, the body is connected to a fixing shaft through bolts, the input shafts are connected with the brake through splines, one end of each gear is connected with each input shaft in a gear meshing manner, the other end of each gear is connected with a shaft 9 through a flat key, the shaft 9 is fixed on the casing through a tapered roller bearing and is fixed on the body through another tapered roller bearing, and a sun gear shaft is connected with the shaft 9 through a spline. By the aid of the three input shafts arranged in the hoisting speed reducer, the purpose of increasing torsion by three inputs is achieved. The three-input hoisting speed reducer is simple in structure and is cost-saving.
Description
Technical field
The utility model relates to the reductor field.
Background technology
Planetary reducer is because of having high rigidity, high precision (single-stage can be accomplished in 1 minute), and high driving efficiency (single-stage is at 97%-98%), high moment of torsion/volume ratio, advantages such as maintenance-free are widely used in mechanical field.But planetary reducer is owing to reasons in structure, and single-stage speed ratio maximum generally is no more than 10, and progression generally is no more than 3, complete machine speed ratio limited size.Therefore the list of conventional confguration is imported hoisting speed reducer output torque limited size, can not satisfy the demand of bigger specification hoisting mechanism.
Summary of the invention
The purpose of the utility model is to provide a kind of scheme of three parallel inputs, to obtain the hoisting speed reducer of compact conformation, high pulling torque.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
Three input hoisting speed reducers comprise casing, body, drg, and wherein casing is connected with body through bolt; Drg is connected with casing through bolt; It is characterized in that: three identical input shafts are fixed on the casing through tapered roller bearing, are fixed on the body through another tapered roller bearing, and body passes through bolted connection on anchor shaft; Input shaft links to each other with drg through spline; Gear one end links to each other with input shaft through gear mesh, the other end through flat key with spool be connected, spools 9 are fixed on the casing through tapered roller bearing; Be fixed on the body through another tapered roller bearing, sun wheel shaft is connected with axle through spline.
The advantage of the utility model is: the utility model is through being provided with three input shafts to reach the purpose that three inputs increase moment of torsion in reductor, the utility model is simple in structure, the saving cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with Fig. 1.
Among Fig. 1: three identical input shafts 13 are fixed on the casing 4 through tapered roller bearing 12, are fixed on the body 11 through another tapered roller bearing 10; Body 11 passes through bolted connection on anchor shaft 7; Axle 9 is fixed on the casing 4 through tapered roller bearing 2, is fixed on the body 11 through another tapered roller bearing 6; Casing 4 is connected with body 11 through bolt; Drg 1 is connected with casing 4 through bolt; Sun wheel shaft 8 links to each other with axle 9 through spline; Axle 9 links to each other with gear 5 through flat key 3; Gear 5 links to each other with input shaft 13 through gear mesh; Input shaft 13 links to each other with drg 1 through spline.
Three input hoisting speed reducers are realized three inputs through three input shafts are set; Input torque is merged. attachment face is in same plane; High speed level three gear wheel shaft arrangement in parallels; Back two-stage is a planetary transmission, makes the reductor integral structure very compact. promptly practice thrift cost and space, can increase exponentially output torque again simultaneously.
