Abstract
The invention relates to a rotary transmission mechanism for realizing two-way input and one-way output and belongs to the technical field of transmission mechanical structures. The transmission mechanism is used for converting rotary motion in a positive direction and a negative direction of an input shaft into a single rotary direction motion and outputting the single rotary direction motion through a transmission system consisting of a group of bevel gears, and the positive transmission and the negative transmission of the input shaft can be transmitted to an output wheel at equivalent speed. The rotary transmission mechanism has the advantages of compact structure, similar driving efficiency in the positive direction and the negative direction and extremely good application prospect.
Description
Technical field
The present invention relates to a kind of rotary drive mechanism that is used to realize the unidirectional output of two-way input, belong to the gearing technical field of structures.
Background technique
The general characteristics of transmitting the transmission system of rotation motion are to give regularly when the direction of input rotation motion, and the direction of the rotation motion of output is also confirmed, and when the direction of input rotation motion changed, the direction of output shaft also changed simultaneously.Though some transmission device can remain unchanged the direction of output movement through transmission system, need complicated transmission system, and certain variation also takes place in velocity ratio usually when the power input direction changes more.This makes the application in some occasion be restricted.
Summary of the invention
The present invention utilizes one group of bevel gears that constitutes Gear Planet Transmission between input shaft and output wheel, to set up drive connection; And between planetary carrier and the input shaft, between planetary carrier and fixing frame overrunning clutch is installed respectively; Make that be set at forward this moment when input shaft turns round by a certain direction, the overrunning clutch between planetary carrier and the input shaft is sealed; Thereby power is directly passed to output wheel, realizes the revolution in the same way synchronously of input shaft and output wheel; And when input shaft turns round by opposite direction; Be set at reverse this moment, can drive planetary carrier and produce the trend of rotating in the same way, and the overrunning clutch between this moment planetary carrier and fixing frame is sealed; Planetary carrier and frame are fixed; The power of input shaft through with the fixing input bevel gear of input shaft, drive bevel planet gear, and and then drive and the output wheel output bevel gear of fixing; Realize the drive path of input shaft to output wheel; Because this moment, bevel planet gear became the transition gear of a dead axle, thereby realized output wheel and the reverse drive connection of input shaft constant speed, output wheel turns to the gyratory directions that still keeps original constant when promptly having realized the input shaft reversed turning.
The technological scheme that the present invention adopts is following:
A kind of driving mechanism with the unidirectional output of fast two-way input comprises frame, input shaft, bearing one, bearing two, overrunning clutch one, output wheel, output bevel gear, overrunning clutch two, input bevel gear, bevel planet gear support and bevel planet gear.Input shaft connects with frame through bearing one; Input shaft overlaps with input bevel gear axis, and realizes being fixedly connected, installation overrunning clutch one between one section axle on the input shaft and the bevel planet gear support; Overrunning clutch one makes when the input shaft forward turns round; Sealed between bevel planet gear support and input shaft, and during the input shaft reversed turning, input shaft separates with the bevel planet gear support; The bevel planet gear support is outside is distributed with several turning axlees equably, is used to install bevel planet gear; Bevel planet gear one side and input bevel gear engagement, opposite side and the engagement of output bevel gear, the output bevel gear is fixed with output wheel, and connects through bearing two realization rotary pairs with importing between bevel gear at output wheel; Simultaneously, a side of bevel planet gear support is provided with columnar structured center hole from the output bevel gear and stretches out, and between the bearing support of columnar structured and frame, overrunning clutch two is installed.Overrunning clutch two makes when bevel planet gear support forward turns round; The bevel planet gear support separates with the bearing support of frame; The bevel planet gear support can rotate; And when the bevel planet gear support is desired reversed turning, sealed between the bearing support of bevel planet gear support and frame, thus make the bevel planet gear support fixed.
The transmission system that the present invention constitutes through one group of cone gear is converted into single gyratory directions output with the positive and negative two direction rotation motions of input shaft, and forward and reverse transmission of input shaft all be delivered to output wheel with equivalent rotating speed.Compact structure of the present invention, forward and reverse driving efficient is close, has good application prospects.
