Abstract
The invention discloses a gear type double selection transmission device which solves the problem that the existing coupler and clutch can not meet the requirement of multiple input shafts and has the advantages of simple structure, convenient use, favorable performance of satisfying multi-shaft power input and the like. The invention is characterized in that the device comprises an output shaft, wherein a first input shaft and a second input shaft matched with the output shaft are respectively arranged at both sides of the output shaft, selection devices are arranged on two input shafts, and the output shaft is engaged with the first gear of the first input shaft and the second gear of the second input shaft.
Description
Technical field
The present invention relates to a kind of transmission device, relate in particular to a kind of gear type double selection transmission device.
Background technique
Mostly has only a power source in present machinery and the machine system, so also only need a clutch that power is made transferring power or two kinds of selections of non-transferring power.But in some cases, the power source in the mechanical system can have two or more power sources more than one.At this moment just need make following selection: 1. select transferring power A; 2. select transferring power B; 3. transferring power not, but also do not have mature technique and device to solve this problem at present.
For example when the source of equipment dynamic dual mode is arranged, normal condition is that motor provides power, is by power manually is provided under the fortuitous event when having a power failure.This situation under the condition of prior art and device, must use two cover clutches to transmit the power of different power sources respectively, then two power is incorporated on the output shaft.For two power are not interfered, cause danger, must control two clutches simultaneously, make a clutch in conjunction with the time another one must disconnect, form interlocking.Such Technology Need is complicated mechanical system and control system more, and easier causing danger, and Security and reliability are all lower.
For the situation that is similar to such power input that two or more is arranged, as a kind of electric power and a kind of man power, perhaps the special applying working condition owing to machine changes especially greatly, thereby requires two kinds of different power sources (as motor and internal-combustion engine) that power is provided.
Summary of the invention
Purpose of the present invention is exactly in order to solve the problem that present coupling and clutch can not satisfy many input shafts needs, provides a kind of and has simple in structurely, easy to use, can effectively satisfy the gear type double selection transmission device of advantages such as multiaxis power input.
For achieving the above object, the present invention adopts following technological scheme:
A kind of gear type double selection transmission device, it comprises an output shaft, the output shaft both sides are respectively equipped with first input shaft with matching and second input shaft, on two input shafts selection device is installed, output shaft is by the second input gear engagement of the first input gear or second input shaft of the output gear and first input shaft.
Described selection device comprises the long key I that is installed in first input shaft, and long key I upward installs the first input gear, is provided with chuck I at first front end of importing gear, in the draw-in groove of the chuck I and the first input gear formation snap ring I is installed;
Second input shaft is provided with long key II, and the second input gear is installed on long key II, is provided with chuck II at the second input gear front end, in the draw-in groove of the chuck II and the second input gear formation snap ring II is installed;
Turning lever is connected with snap ring II with snap ring I, and the turning lever middle part is hinged on the bearing.
Of the present invention considering will be with transmission of power to main power shaft, there is dual mode in the source of power, a kind of is that motor provides power, another kind is by power (mainly being to use under the fortuitous event when having a power failure) manually is provided, in this case, can not achieve the goal by speed changer, if transmit power respectively with regard to hell to pay with two cover coupling or clutch system.For this situation, but I have designed the device of this two-way choice.Perhaps the special applying working condition owing to machine changes especially greatly, thereby requires two kinds of different power sources (as motor and internal-combustion engine) that power is provided, and also needs to use this device.In some cases, for guaranteeing the reliability of machine run, two cover power sources can be installed, to prevent that machine can decommission after a power source lost efficacy.This situation also needs to use this device.
Working principle of the present invention is: on first, second input shaft separately chuck and the input gear be to be cemented in one, gapped between input gear and the axle, long key is set in the gap, reason owing to long key, can not relatively rotate between input gear and input shaft, but gear can slidably reciprocate in the long key section of axle, and the effect of long key is that guiding input gear slides and transferring power.Stirring snap ring and be the recess that is stuck in chuck and input gear junction and forms is in the annular groove, and the internal diameter of snap ring is bigger than the external diameter of chuck herein, so chuck is free to rotate, and snap ring can not rotate.Turning lever is fixedlyed connected with snap ring, cannot relatively rotate, and the interposition of turning lever is equipped with a hinge and is hinged on the bearing, and bearing is fixed on support or ground.Like this, by rotating turning lever, can select which input gear and output gear engagement, thereby reach the axle of selecting different inputs, the purpose of different dynamic input.And this design has a very big advantage, and the design that is exactly turning lever has formed interlocking to two gears, it guaranteed two input gears can be not simultaneously and output gear mesh, cause danger.Stir when being first input gear and the output gear engagement when turning lever, torque is imported from first input shaft, by engaging gear, exports from output shaft.In like manner, when the second input gear and output gear engagement, torque is imported from second input shaft, by engaging gear, exports from output shaft.For the operation of turning lever, can use manually-operable, also can the electrification operation.Such as, control motor by button, provide power to come the push-and-pull turning lever.
The invention has the beneficial effects as follows:
1. this pair of selection driving mechanism biggest advantage is exactly the double selectivity with torque transfer.The power transmission of common between centers is by coupling or clutch, but the transmission torque that coupling or clutch can only be single, and this mechanism torque transmitted has alternative.
2. second advantage is exactly simple in structure, and compactness, the main body of entire mechanism are exactly by three gear structures, chuck, and snap ring, driving lever is formed.Structural refinement.
3. cost is low.The number of spare parts of entire mechanism is little, and mostly is standard piece.So manufacturing expense is little.
4. power transfer efficiency height operates reliably.
5. easy to operate.
6. the design of turning lever forms interlocking, thereby Security is good.
