Description
Technical field
The invention belongs to mechanical transmission fields more particularly to a kind of automatic gear shift transmission devices.
Background technology
Conventional mechanical transmission includes gear drive, chain drive, V belt translation and worm drive etc., and wherein worm drive are to utilize
The engagement of screw rod and nut comes passing power and movement, is mainly used for convert rotational motion being in line movement, torque is converted
At thrust.Worm drive can be divided into slip screw transmission and rolling spiral drive, using very extensive in engineering, such as spiral thousand
Jin top and ball-screw.Traditional the mostly of worm drive use are effort-saving mechanisms, no matter whether output end has load, input terminal fortune
The stroke of dynamic stroke ratio output end motion is much greater, so that worm drive rate of climb in zero load is slower, causes
The reduction of waste of time, work efficiency.
Invention content
In order to overcome above-mentioned deficiency in the prior art, the present invention provides one kind, and worm drive can be made fast in zero load
Speed rises, the automatic gear shift transmission device that automatic slowly rises again when loaded.
The present invention uses following technical scheme.
The automatic gear shift transmission device of the present invention determines torquer, input shaft by cyclic train, input, exports and determine torque dress
It sets, output shaft, unilateral bearing composition；The cyclic train is by input gear, preceding planetary gear, rear planetary gear, fixed gear, connection
Axis and planet carrier composition；The input gear is engaged with preceding planetary gear, and rear planetary gear is engaged with fixed gear, preceding planetary gear and rear row
Star-wheel is respectively fixedly connected at the both ends of connecting shaft, planet carrier with connect axis connection；It is solid with input gear that torquer is determined in the input
Even, and input is determined torquer and is sleeved on input shaft；The output determines torquer and is sleeved on output shaft one end, and output shaft is another
One end is sleeved in fixed gear centre bore；The unilateral bearing inner ring is connected with input shaft, outer ring and output shaft fixed connection.
The input is determined torquer and is made of outer ring, preceding spring, preceding roller, preceding screw；Outer ring is circumferentially equal
The multiple interior square grooves of cloth, preceding spring is equipped in interior square groove, and preceding spring one end and the mode being connected through a screw thread are mounted on outside outer ring
Preceding screw contact on cylindrical surface, the other end and preceding roller-contact, preceding roller are contacted with the arc groove on input shaft again.
The output is determined torquer and is made of rear spring, rear roller, rear screw；It is uniformly distributed multiple interior on planet carrier inner periphery
Square groove, rear spring is equipped in interior square groove, and rear spring one end and the mode being connected through a screw thread are mounted on the rear spiral shell on planet carrier
Nail joint is touched, and the other end and rear roller-contact, rear roller are contacted with the arc groove on output shaft again.
The present apparatus is being fixed on worm drive before use, needing first to be driven fluid drive by the fixed gear on the device
In device frame, by output sleeve on helicoidal gear input shaft.When helicoidal gear is in zero load, turn clockwise
The inner ring of driven input shaft, the unilateral bearing being on the one hand connected with input shaft can rotate clockwise；On the other hand, the power of input shaft
Determine torquer by input and pass to cyclic train, finally so that planet carrier can also rotate clockwise, determines torque by output
The effect of device imparts power to output shaft, and unilateral bearing outer ring is driven to rotate clockwise, at this time unilateral bearing outer ring
Speed is more than the speed of inner ring, and unilateral bearing, which is in, surmounts state, and the rotating speed of the output shaft of whole device is more than input shaft at this time
Rotating speed, helicoidal gear output shaft can rapid increase.When helicoidal gear loads so that act on the resistance of output shaft
Torque will increase, and when the moment of resistance determines torquer more than input determines the predetermined torque of torquer with output, two are determined torque
Device will skid, and output shaft will slow down so that the speed of unilateral bearing outer ring is eventually equal to the speed of inner ring, unilateral bearing
It is at synchronous regime, at this point, the torque acted on input shaft can be directly passed to output shaft and be ultimately applied to spiral biography
On dynamic device input shaft, helicoidal gear at this time will slowly rise.
The beneficial effects of the invention are as follows：1, when empty, which is a speeder so that helicoidal gear is defeated
Shaft can rapid increase, improve efficiency；2, when loaded, which is automatically converted to a constant speed device so that spiral passes
Dynamic device output shaft can slowly rise.
