Description
Technical field
The utility model relates to a kind of change-speed box, and specifically a kind of winch double-speed speed change gear, belongs to mechanical transmission fields.
Background technology
Winch is the small-sized weight-lifting equipment of a kind of reel lay winding wire ropes or chain lifting or traction weight.Winch can be used alone, and also can do lifting, build the road and constituent elements in the machinery such as mine hoisting, because of simple to operate, wiring amount is large, dislocation convenient and widespread use.The material mainly applying to building, hydraulic engineering, forestry, mine, harbour etc. is elevated or puts down and drags.Change-speed box is then the device changing the machine run speed such as lathe, automobile, trac. or tractive force, and the gear different by many diameter forms.Winch usually and change-speed box support the use.At present, gear transmission has many kinds, modally will count parallel-axis type speed variator, and it is that mode by moving hand handle stirs shifting slide gear, makes it carry out engagement to realize speed change from the gear of the different number of teeth.The maximum problem of this change-speed box must first have a power failure before being speed change machine, otherwise, gear can be caused to crack a joke.Also have a kind of planetary transmission for winch, comprise the parts such as sun wheel, gear ring and two pinion carriers, two gear rings are made of one, and sun wheel is connected with motor output shaft by key.Its manufacturing process is complicated, and maintenance cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of winch double-speed speed change gear, when not having a power failure machine, realize speed change and the parking of winch, and the structure of making every effort to change-speed box is simple, anufacturability good.
For achieving the above object, this winch double-speed speed change gear, comprise casing, sun wheel and pinion carrier, sun wheel is connected with motor output shaft by key, also comprise brake wheel I, gear ring I, double-planetary gear, planet wheel spindle, gear ring II, brake wheel II, the number of described pinion carrier is one, brake wheel I adopts key to be connected with gear ring I, the neck of gear ring I has bearing to support, the two ends axle journal of planet wheel spindle respectively has bearing to support, double-planetary gear is contained in pinion carrier by planet wheel spindle, bearing is had to support between double-planetary gear and planet wheel spindle, the left end neck of gear ring II is connected with brake wheel II by key, and have bearing to support, the big gear wheel of double-planetary gear engages with sun wheel and gear ring I simultaneously, the miniature gears of double-planetary gear engages with gear ring II, brake wheel I and brake wheel II are arranged on casing outside, the axle head that pinion carrier left end stretches out is provided with key, as output shaft.
Compared with prior art, the beneficial effects of the utility model are: when not having a power failure machine, by carrying out brake application to brake wheel I or brake wheel II respectively, can realize the speed change of winch, when two brake wheels not brake application time winch stall.Speed change is convenient, and reduces the frequent starting of motor.This speed changer structure is simple, manufacture and assembly process process good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. sun wheel, 2. brake wheel I, 3. gear ring I, 4. double-planetary gear, 5. planet wheel spindle, 6. casing, 7. pinion carrier, 8. gear ring II, 9. brake wheel II.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
In FIG, a kind of winch double-speed speed change gear, comprise casing 6, sun wheel 1 and pinion carrier 7, sun wheel 1 is connected with motor output shaft by key, also comprise brake wheel I 2, gear ring I 3, double-planetary gear 4, planet wheel spindle 5, gear ring II 8, brake wheel II 9, the number of described pinion carrier 7 is one, brake wheel I 2 adopts key to be connected with gear ring I 3, the neck of gear ring I 3 has bearing to support, the two ends axle journal of planet wheel spindle 5 respectively has bearing to support, double-planetary gear 4 is contained in pinion carrier 7 by planet wheel spindle 5, bearing is had to support between double-planetary gear 4 and planet wheel spindle 5, the left end neck of gear ring II 8 is connected with brake wheel II 9 by key, and have bearing to support, the big gear wheel of double-planetary gear 4 engages with sun wheel 1 and gear ring I 3 simultaneously, the miniature gears of double-planetary gear 4 engages with gear ring II 8, it is outside that brake wheel I and brake wheel II are arranged on casing 6, the axle head that pinion carrier 7 left end stretches out is provided with key.
Preferred scheme is: in pinion carrier 7, install two double-planetary gears 4; In order to keep balance under high-speed operation state, two double-planetary gears 4 can be arranged in pinion carrier 7 according to diagonal row.
Sun and planet gear can realize the gear of four kinds of various combinations: 1, low gear state, and initiatively, pinion carrier 7 is passive, and gear ring is motionless for sun wheel 1; Middle gear state, sun wheel 1 is motionless, and pinion carrier 7 is passive, and gear ring is initiatively; High gear state, sun wheel 1 is motionless, and initiatively, gear ring is passive for pinion carrier 7; Reverse gear state, initiatively, pinion carrier 7 is motionless, and gear ring is passive for sun wheel 1.When all movement parts are all unfettered, change-speed box is in neutral, winch stall.
When not having a power failure machine, by carrying out brake application to brake wheel I 2 or brake wheel II 9 respectively, the speed change of winch can be realized, when two brake wheels not brake application time winch stall.Speed change is convenient, and reduces the frequent starting of motor.Owing to only have employed a pinion carrier 7, this speed changer structure is simple, manufacture and assembly process process good.
