Since the first spring is constantly in compression Pre strained state in the present invention, in normal state, friction block is in the first bullet
There is certain friction pressure between output shaft, when output shaft rotation, output shaft will drive mounting shell and turn under the action of spring
Dynamic, mounting shell rotation drives the driving cylinder rotation for installing it, and driving cylinder rotation drives three friction blocks around output shaft turn
Dynamic, three friction blocks are rotated around the torque band driven input shaft that output shaft rotation will generate under the action of the friction pressure,
I.e. in normal state, output shaft can be rotated with input shaft；When three friction blocks are rotated around output shaft, three friction blocks are just
It will receive a centrifugal force, under the action of the centrifugal force, three friction pressures between friction block and output shaft will become smaller,
Driving force between output shaft and three friction blocks will die down, so the transmission mechanism is suitable for the certain i.e. transmitting torque of load
In certain mechanism certain with output revolving speed；Critical speed and transmitting torque appropriate are selected according to institution requests before the use
Suitable for the transmission mechanism of the mechanism, after transmitting coincide, after critical speed W is selected, when input speed is less than critical speed W
When, three not will do it skidding between friction block and output shaft, input shaft normally can drive output shaft to rotate, work as input speed

Dynamic output shaft rotation；When input speed is greater than critical speed W the larger value, three will disengage between friction block and output shaft
Sliding, input shaft cannot drive output shaft to rotate；So selecting input speed to be less than according to institution requests when selecting transmission mechanism
The transmission mechanism of critical W.
In the present invention when the driving mechanism after prolonged use, three friction blocks will be worn, in this state
Under, since the first spring is in compression Pre strained state in the initial state, so at this time under the action of the pressure of the first spring,
Adjusting block will move down, and adjusting block, which moves down, to make first gear rotate, and first gear rotation drives first turn
Axis rotation, first rotating shaft rotation drive second gear rotation, and second gear rotation will make three friction blocks to close to output
The side of axis is mobile, and the extent of damage of its long-time friction is made up by the movement of friction block.
Since the diameter of second gear is 3 times of first gear diameter in the present invention, effect is, when friction block be damaged to
When being moved a certain distance close to the side of output shaft, the distance that adjusting block moves down be friction block moving distance three/
One, the first spring relative to the distance being extended under normal condition also be friction block moving distance one third, the first bullet

Three arc-shaped racks form an annular rack in the present invention, and effect is on the one hand to ensure that three friction blocks move
Dynamic amplitude is identical, while passing through the cooperation of three arc-shaped rack top shoes and sliding slot, when the movement of one of arc-shaped rack
Amplitude is greater than other two arc-shaped rack, but be not greater than sliding block arc slot inner casing it is mobile apart from when, the arc-shaped rack
Movement will not cause to interfere in other two.
In the present invention when the impaired degree of the friction of three friction blocks is identical, a sidesway of the friction block to close output shaft
Dynamic distance is identical, and after the completion of movement, three friction blocks are identical to the friction pressure of output shaft, biography of the friction block to output shaft
Relatively stable, i.e. biography good dynamic balance is moved, when the degree for having the friction an of friction block impaired in three friction blocks is greater than other two
A, and when differing smaller, three friction blocks will be different to the mobile distance in the side close to output shaft, the friction extent of damage compared with
The mobile distance of two small friction blocks is less than another, and arc-shaped gear corresponding with the friction lesser friction block of the extent of damage
The item distance mobile relative to the corresponding arc-shaped rack of the friction biggish friction block of the extent of damage is not enough to mutually drive, this feelings
Under condition, three friction blocks and output shaft can be all in contact, and only corresponding first spring of three friction blocks is to three friction blocks
Friction pressure become different, transmission is not sufficiently stable, but under the action of second gear and first gear, with the impaired journey that rubs
The stroke variation for spending corresponding first spring of biggish friction block relative to other two the first spring is smaller, to friction block
Friction pressure influences less, such case, and output shaft, will not be to defeated in the driving underdrive of three friction blocks or more stable
Shaft affects greatly, simultaneously as friction block apart from output shaft axial line distance it is slightly different caused by pulse be not very big
Also can receive, mainly prevent from being driven at this time it is bad caused by influence and receive faint bounce deleterious effect.In the present invention when
When the degree for having the friction an of friction block impaired in three friction blocks is larger relative to other two, which, which drives, is corresponded to
Arc-shaped rack mobile distance when being enough to drive other two arc-shaped rack mobile, since other two arc-shaped rack is corresponding
Two friction blocks and output shaft have been in intimate-association state after moving a certain distance, the two friction blocks cannot continue to
Output shaft side is mobile, i.e., the two friction blocks will be stuck another friction block, immovable, so that itself and output shaft
Aerial, in this state, output shaft drives simply by two friction blocks, and transmission performance reduces, but whole in order to prevent
A equipment because friction block is excessively different apart from output shaft axial line distance and it is normal unacceptable significantly jumping effect occur
Transmission, so in this case, can only cast out a friction block, drives output shaft to rotate, at this time by two friction blocks
It mainly prevents from influencing caused by excessive bounce and receiving transmission performance deleterious effect.

Dynamic that first rotating shaft 24 is driven to rotate, the rotation of first rotating shaft 24 drives second gear 21 to rotate, and the rotation of second gear 21 will make
Three friction blocks 19 are mobile to the side close to output shaft 1, made up by the movement of friction block 19 its long-time friction by
Damage degree.
Due to 3 times that the diameter of second gear 21 is 6 diameter of first gear in the present invention, effect is, when friction block 19
It is damaged to when being moved a certain distance close to the side of output shaft 1, the distance that adjusting block 20 moves down is that friction block 19 is mobile
The one third of distance, the first spring 10 are also 19 moving distance of friction block relative to the distance being extended under normal condition
One third, the first spring 10 are relatively small to the preload pressure reduction amount of friction block 19, and the interval of correction is elongated, transmission mechanism

The amplitude of 19 movements is identical, while by the cooperation of three arc-shaped racks 9 top shoes 23 and sliding slot 22, when one of arc-shaped gear
The mobile amplitude of item 9 is greater than other two arc-shaped rack 9, but be not greater than sliding block 23 arc slot inner casing it is mobile apart from when,
The movement of the arc-shaped rack 9 will not cause to interfere in other two.
In the present invention when the impaired degree of the friction of three friction blocks 21 is identical, friction block 21 is to close to output shaft 1
The mobile distance in side is identical, and after the completion of movement, three friction blocks 21 are identical to the friction pressure of output shaft 1, friction block 21
It is relatively stable to the transmission of output shaft 1, that is, good dynamic balance is passed, when the friction for having a friction block 21 in three friction blocks 21 is impaired
Degree be greater than other two, and when differing smaller, three friction blocks 21 will to the mobile distance in the side close to output shaft 1
Difference, the mobile distance of lesser two friction blocks 21 of the friction extent of damage are less than another, and with the friction extent of damage compared with
The small corresponding arc-shaped rack 9 of friction block 21 is moved relative to the friction extent of damage corresponding arc-shaped rack 9 of biggish friction block 21
Dynamic distance is not enough to mutually drive, and in this case, three friction blocks 21 and output shaft 1 can be all in contact, and only three
Corresponding first spring 10 of friction block 21 becomes different to the friction pressure of three friction blocks 21, and transmission is not sufficiently stable, but
Under the action of first gear and second gear, with corresponding first spring 10 of the friction biggish friction block 21 of the extent of damage relative to
The stroke variation of other two the first spring 10 is smaller, influences less on the friction pressure of friction block 21, such case, output
Axis 1 will not affect greatly output shaft 1 in the driving underdrive of three friction blocks 21 or more stable, simultaneously as
Friction block apart from output shaft axial line distance it is slightly different caused by pulse be not that can also receive greatly very much, mainly prevent from passing at this time
Move it is bad caused by influence and receive faint bounce deleterious effect.When there is a friction block in three friction blocks 21 in the present invention
When the impaired degree of 21 friction is larger relative to other two, the friction block 21 drive corresponding arc-shaped rack 9 it is mobile away from
When from being enough to drive other two arc-shaped rack 9 mobile, due to 9 corresponding two friction blocks 21 of other two arc-shaped rack with it is defeated
Shaft 1 has been in intimate-association state after moving a certain distance, the two friction blocks 21 cannot continue to output shaft side
Mobile, i.e., the two friction blocks 21 will be stuck another friction block 21, immovable, so that it is aerial with output shaft 1,
In this state, output shaft 1 drives simply by two friction blocks 21, and transmission performance reduces, but entire in order to prevent
There is unacceptable significantly jumping effect and normally passes because friction block is excessively different apart from output shaft axial line distance in equipment
It is dynamic, so in this case, a friction block 21 can only be cast out, output shaft 1 is driven to rotate by two friction blocks 21.
Specific embodiment: when the transmission mechanism designed using the present invention, in normal use process, output shaft 1 can band
Dynamic mounting shell 2 rotates, and the rotation of mounting shell 2 drives the driving cylinder 4 for installing it to rotate, and the driving rotation of cylinder 4 drives three to rub
Block 19 is rotated around output shaft 1, and three friction blocks 19 will drive defeated around the rotation of output shaft 1 under the action of the friction pressure
Enter the rotation of axis 3, i.e. input shaft 3 drives output shaft 1 to rotate；When the driving mechanism after prolonged use, three friction blocks 19 are just
It will receive abrasion, in this state, since the first spring 10 is in the initial state in compression Pre strained state, so existing at this time
Under the action of the pressure of first spring 10, adjusting block 20 will be moved down, and adjusting block 20, which moves down, will make the first tooth
