Tool drive system is very extensive.
Existing speed reducer mainly has gear set speed reducer and worm reduction gear, and these two types of speed reducer principles are simple, application
It is commonplace, but there are certain deficiencies:
1, gear set speed reducer is mainly the purpose that deceleration is realized by the gear ratio of size gear set, input gear
Radix it is big, it has not been convenient to the matching of output gear is slowed down slow, while directly by gear matches, engagement tightness is wanted between gear
Ask high, and the setting of inconvenient component；
2, worm reduction gear be mainly characterized by have the function of reverse self-locking, can have a biggish reduction ratio, input shaft and
Not on the same axis, also not in the same plane, but general volume is larger, and worm and gear friction is big, transmission effect for output shaft
Rate is low, and precision is not high.
Utility model content
The purpose of this utility model be for existing speed reducer middle gear group speed reducer input gear radix it is big, it has not been convenient to
The matching of output gear is slowed down slow, and the general volume of worm reduction gear is larger, and worm screw friction is big, and transmission efficiency is low, low precision
Deficiency provides a kind of bidirectional self-locking retarder, which uses symmetrical eccentric wheel and active operation arm configuration, subtracts
Speed is fast, loss is small.
In order to solve above-mentioned prior art problem, the technical solution of the utility model is:
The utility model bidirectional self-locking retarder, it includes solid on fulcrum post and input shaft and output shaft and output shaft
Surely the output wheel and casing being arranged；
Symmetrical first eccentric wheel, the second eccentric wheel are fixedly installed on the wheel for inputting；
The bidirectional self-locking retarder further includes the first working arm, the second working arm, first working arm, the second work
One end of arm forms strip-shaped hole, and first working arm, the second working arm are rotatably dispose on input shaft by strip-shaped hole, institute
State the first working arm, the other end of the second working arm is output end；
Output end when advancing horizontally to the right of first working arm, the second working arm, first working arm, the second work
The output wheel made on the output end and output shaft of arm is connected；
The connecting mode is U-shaped mouth mode or gear manner, when the connection is U-shaped mouth mode, first work
Arm, the second working arm output end be shaped to lateral U-shaped mouth, the output wheel annular space on the output shaft is provided with multiple
Round steel pin, the circle steel pin can be connected in U-shaped mouth；
It is described connection be gear manner when, first working arm, the second working arm output end be shaped to gear teeth structure,
Output wheel on the output shaft is shaped to match the gear of the gear teeth structure, first working arm, the second working arm
Output end is meshed with output wheel by gear；
First working arm, the second working arm are shaped to hollow first close to the position of output end and set chamber, second
Set chamber, described first sets chamber, second sets the shape that chamber matches first eccentric wheel, the second eccentric wheel, and described first
Eccentric wheel, the second eccentric wheel activity set chamber embedded at described first, second set chamber.
The bidirectional self-locking retarder utilizes the principle of eccentric wheel, and first working arm, the second working arm are by the first bias
Wheel, the second eccentric wheel drive advance up and down and left and right is advanced, first working arm, second working arm or so advance so that
Couple and separate, first working arm, second with output end and the output wheel intermittent of the first working arm, the second working arm
Working arm is advanced up and down so that the output end with the first working arm, the second working arm drives output wheel stepping, due to the first bias
Wheel, the second eccentric wheel be symmetrical arranged so that the first working arm, the second working arm traveling up and down and left and right advance respectively alternately into
Row, to drive output wheel continuous rotation, when wheel for inputting rotates one week, output wheel stepping twice, passes through the step of setting output wheel
Number, to achieve the purpose that deceleration.
The utility model bidirectional self-locking retarder, its advantages have:
1, the bidirectional self-locking retarder using symmetrical eccentric wheel and active operation arm configuration, slow down that fast, loss is small；
2, rotation input is changed into step-by-step system by eccentric wheel by the speed reducer, and is driven by active operation arm,
Structure setting is flexible, and the gear ratio for facilitating matching different carries out output conversion, slows down fast；
3, what the speed reducer used is rolling friction, and equipment attrition is small, and power loss is small when deceleration；
4, the speed reducer structure is simple, at low cost, good assembles, is wide with field；
5, the speed reducer can the oppositely arranged realization speedup of input and output, or increase input and output switching construction, realize
Speed change is extensive with field.
