Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited in following examples.
As shown in figure 1, a kind of escapement rolling sleeve type reductor, including housing, input shaft 1, output shaft 2 and escapement driver
Structure.
The housing can be integral housing, can be Split type casing.As shown in figure 1, integral housing include by
Output oil seal is installed on the left of the machine base body (support and raising middle flask body by integral forming) that support 91 is constituted with middle casing 93, machine base body
Drive end bearing bracket 94 is installed on the right side of lid 92, machine base body.Split type casing includes support 91, the output oil seal lid on the left of support
92nd, on the right side of support split type shell is omitted in middle casing 93 and the drive end bearing bracket 94 installed in the middle right side of casing 93, figure
Body.
The input shaft and output shaft are coaxially arranged and are rotatably positioned at housing two ends.Wherein：Output shaft passes through
Output shaft bearing 29 is installed in rotation in support, and the left end of output shaft stretches out hull outside after passing through output oil seal lid, defeated
Shaft right-hand member is flange 21 and the flange is located in raising middle flask body；The input shaft is rotatably mounted in raising middle flask body, input shaft
Right-hand member pass through and stretched out after drive end bearing bracket hull outside (drive end bearing bracket, which is provided with, to be used to coordinate the bearing of input shaft 19 of input shaft), input
The left end of axle, which is rotatably positioned on the flange of output shaft, (also is provided with the bearing of input shaft for coordinating input shaft on flange
19)。
The escapement transmission mechanism is arranged in the raising middle flask body of housing and the power of input shaft can be transferred into output
On axle.The escapement transmission mechanism includes capacity eccentric bearing 4, some bearing pins 5, escapement 3, pin gear ring 6.
The escapement is swingably positioned between output shaft flange and drive end bearing bracket, is formed respectively with escapement positioned at center
Axis hole 31, the pin shaft hole 32 for being evenly arranged in axis hole surrounding and the external toothing 33 on outer circumference surface.The axle of escapement axis hole
Line is parallel to the axis of input shaft, and the quantity of escapement is at least a piece of, preferably two panels or three (two panels escapement is in accompanying drawing).
The capacity eccentric bearing is fixed on the left end of input shaft, and capacity eccentric bearing can use split type capacity eccentric bearing, can also use
Integral one-piece mainshaft is held.As shown in figure 5, split type capacity eccentric bearing include be arranged on input shaft on eccentric bushing 41, be respectively mounted
Bearing inner race 42 on each eccentric part of eccentric bushing, the roller 43 being separately mounted between bearing inner race and escapement axis hole.Such as
Shown in Fig. 6, integral one-piece mainshaft contracts the eccentric inner ring 44 included on input shaft, is separately mounted to each inclined of eccentric inner ring
Roller 43 between center portion and escapement axis hole.It is relatively simple for structure that the integral one-piece mainshaft is held, and can use bigger
Input shaft so as to lifting input torque.When escapement quantity is two panels, swing angle of this two panels escapement relative to input shaft
For 180 degree, when escapement quantity is three, this three escapements are 120 degree relative to the swing angle of input shaft.
The bearing pin is around being arranged in the surrounding of input shaft and being vertically fixed on the left side of drive end bearing bracket, while these are sold
Axle is also inserted in each pin shaft hole of escapement one by one.When the quantity of escapement is multi-disc, every bearing pin needs to insert different simultaneously
In the pin shaft hole of escapement.The bearing pin is provided with the guide 52 being engaged with escapement spacing hole.
The pin gear ring is fixed on flange on (pin gear ring and flange can be integrally formed), the inner peripheral surface of pin gear ring
Provided with some needle rollers 61, the external toothing of the escapement is engaged with the needle roller of pin gear ring.To reduce friction, in speed than small reductor
In, roll sleeve (being omitted in figure) can be also set on needle roller.
The present invention operation principle be：In the motion process of reductor, input shaft drives escapement to swing, and escapement is by bearing pin
Support and drive pin gear ring to rotate, output shaft is by the low speed rotation power output of pin gear ring；When input shaft just circles, escapement
Backswing, pin gear ring is just turning over a tooth difference with the swing of escapement, so as to be slowed down；Output shaft upper pin gear circle needle roller
Distance to output shaft center is the length (length of the arm of force is distance of the bearing pin to output shaft center in the prior art) of the arm of force,
It can effectively increase output torque by increasing the length of the arm of force in the case where ensureing constancy of volume of the present invention, finally improve
The performance of reductor.
The present invention is simple in construction, using reliability and stable drive, and larger torque is carried with less volume, has met and has subtracted
The development trend of fast machine.The present invention can use horizontal and vertical two kinds of mounting means.
As shown in figure, it is biaxial type, i.e., without motor, reductor input is input shaft, defeated for powerful power
Enter or specific connection request；
The present invention can also directly assembled and dispatched from the factory after motor, mainly using following two structures：
1st, connection method flange-type：As shown in fig. 7, motor A is standard electromotor, motor shaft head connection input shaft can be conveniently objective
The later stage at family is changed, safeguarded；
2nd, motor direct-connected type：As shown in figure 8, motor A interface and spindle nose use off-standard size, motor shaft head is as defeated
Enter axle, so can shorten axial dimension and improve the accuracy of mesh of gear.
