Description
Technical field
The present invention relates to reductor technical field, the manual shift shift fork knot of a kind of small-power reductor
Structure.
Background technology
Some small-power dual-speed-ratio speed reducers in the market, gear-box size is smaller, gentle with hydraulic cylinder
Cylinder is shifted gears, and one is that cost is bigger, and two is that space is inadequate, and size seems inharmonious.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of small-power is slowed down
The manual shift shifting fork structure of machine, simple in construction, gearshift simplicity.
The technical solution adopted for the present invention to solve the technical problems is: manually changing of a kind of small-power reductor
Gear shifting fork structure, has handle, driving lever, a power transmission shaft, and described handle drives driving lever to rotate, described driving lever with
Power transmission shaft is by bonded, and described driving lever top is provided with driving lever contiguous block, and described driving lever contiguous block top sets
Having the screwed hole for connecting handle, described driving lever contiguous block laterally offers the shoulder hole run through, described rank
The left end diameter in ladder hole, more than the right-hand member diameter of shoulder hole, is installed in described shoulder hole and is used for inserting decelerating chassis
Body hole, location coordinate the bearing pin of location, the left end diameter of described bearing pin is more than the right-hand member diameter of bearing pin.
Further, the centre of described bearing pin is provided with and makes bearing pin have the spring of certain pretightning force toward left end,
The right-hand member of described bearing pin installs the screw for making bearing pin separate with casing.
Further, described bearing pin right-hand member is provided with straight pin, and described driving lever contiguous block is provided with for cylinder
The cotter way that pin slips into, pull-out screw rotary screw, straight pin departs from cotter way and is stuck in the end face of driving lever contiguous block
On.
The invention has the beneficial effects as follows: the present invention, by manually pulling handle, drives driving lever to rotate, driving lever and biography
Moving axis is connected by flat key so that drive axis, power transmission shaft drive box house shifting fork structure, it is achieved
Gearshift function.The manual shift shifting fork structure of the small-power reductor of the present invention, because power is little, shift fork changes
Gear needs moment smaller, this kind of small-power manual shift shifting fork structure, and simple in construction easily operates, cost
Low, size is little, and ratio is more suitable on small-power dual-speed-ratio speed reducer.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation that the present invention installs with casing；
Fig. 2 is the schematic front view of manual shift shifting fork structure in the present invention；
Wherein: 1, handle, 2, bearing pin, 3, screw, 4, straight pin, 5, spring, 6, driving lever,
7, power transmission shaft.
Detailed description of the invention
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings be the schematic diagram of simplification only with
The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
As it is shown in figure 1, the manual shift shifting fork structure of a kind of small-power reductor, there is handle 1, driving lever
6, power transmission shaft 7, handle 1 drives driving lever 6 to rotate, and driving lever 6 and power transmission shaft 7 pass through bonded, driving lever 6
Top is provided with driving lever contiguous block, and driving lever contiguous block top is provided with the screwed hole for connecting handle 1, driving lever
Contiguous block laterally offers the shoulder hole run through, and the left end diameter of shoulder hole is more than the right-hand member diameter of shoulder hole,
Install in shoulder hole for insert box body of speed reducer hole, location coordinate the bearing pin 2 of location, the left end of bearing pin 2
Diameter is more than the right-hand member diameter of bearing pin.In Fig. 1, dotted line left part is casing.
The centre of bearing pin 2 is provided with and makes bearing pin 2 have the spring 5 of certain pretightning force, the right side of bearing pin 2 toward left end
End installs the screw 3 for making bearing pin separate with casing.
Bearing pin 2 right-hand member is provided with straight pin 4, and driving lever contiguous block is provided with the cotter way slipped into for straight pin 6,
Pull-out screw 3 rotary screw 3, straight pin 4 departs from cotter way and is stuck on the end face of driving lever contiguous block.
Handle 1 is connected by screw thread and driving lever 6, and handle has certain length, pulls handle, uses low-force
Just can complete gear shift operation.
Driving lever 6 is connected with power transmission shaft 7 by flat key, and when pulling handle 1, driving lever 6 drives power transmission shaft 7
Rotate, it is achieved internal gear shift operation.
The left end diameter of bearing pin 2 is big, and right-hand member diameter is little, so bearing pin 2 can not be directly from the connection of driving lever 6
The right side of block is extracted.
Installing spring 5 in the middle of bearing pin 2, bearing pin 2 has certain pretightning force toward left end so that bearing pin 2 and casing
Location can be coordinated；When gearshift, as long as pulling screw 3, overcome the pretightning force of spring 5, by bearing pin 2 He
Casing separates；Turning handle 1 unclamps after completing gearshift, and spring 5 pretightning force plays a role, bearing pin 2 and case
Body coordinates again location.
The effect of straight pin 4 is: after pulling screw 3, rotary screw 3 certain angle so that straight pin 4
On the end face of the contiguous block being stuck in driving lever 6, accordingly even when unclamp screw 3, bearing pin 2 also will not be turned left bullet immediately
Go out and coordinate with casing；Make shift process to need not haul screw 3, after gearshift terminates, then by spiral shell always
Nail 3 rotation is in situ, and straight pin 4 drops back in cotter way, and bearing pin 2 is rebounded by spring 5, and it is fixed to coordinate with casing
Position, completes a gear shift operation.
The present invention, by manually pulling handle 1, drives driving lever 6 to rotate, and driving lever 6 and power transmission shaft 7 are by flat key even
Connect so that power transmission shaft 7 rotates, power transmission shaft 7 drive box house shifting fork structure, it is achieved gearshift function.
The manual shift shifting fork structure of the small-power reductor of the present invention, because power is little, shifting-fork gear-shifting needs
Moment is smaller, this kind of small-power manual shift shifting fork structure, and simple in construction easily operates, low cost, chi
Very little little, ratio is more suitable on small-power dual-speed-ratio speed reducer.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, related work
Personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.
The content that the technical scope of this invention is not limited in description, it is necessary to according to right
Determine its technical scope.
