Description
Technical field
The present invention is that a kind of landing tee sets few teeth difference bipyramid tooth mechanical differential structure, is related to a kind of deceleration mechanism, especially
It is related to speed difference when a kind of one motor drive bipyramid tooth planetary reducer of use, obtains the T shape of slow-speed of revolution output
Arrange few teeth difference bipyramid tooth mechanical differential structure.
Background technique

Tool field, RV retarder have the advantages that transmission ratio is big, output torque is big, RV reducer structure complexity, disadvantage at high cost,
Constrain the popularization and application of RV retarder.Harmonic speed reducer has the advantages that transmission ratio is big, structure is simple, harmonic speed reducer it is soft
The property strength of gear teeth is low, leads to that the output torque of harmonic speed reducer is small, service life is short.With RV retarder or harmonic speed reducer phase
Than the transmission ratio of planetary reducer is small, and turbine and worm retarder working efficiency is low, harmonic speed reducer cost ratio RV retarder
At low cost, in the standard machinery field of non-articulated robot, the application of harmonic speed reducer is more extensive.
Common harmonic speed reducer includes internal circular spline, flexible gear, wave producer, and under normal circumstances, internal circular spline is than soft
Property more two teeth of gear, wave producer rotate a circle, and the angle of two teeth of relative rotation between internal circular spline and flexible gear is interior
Tooth firm gear and the number of teeth of flexible gear are more, and the angle between internal circular spline and flexible gear when two teeth of relative rotation is smaller,
The transmission ratio of the harmonic speed reducer is bigger, but the more multiple tooth thickness of the number of teeth is smaller, and the gear teeth of internal circular spline and flexible gear are mechanical strong
Spend it is smaller, harmonic speed reducer transmitting torque it is smaller.
Currently, only turbine and worm retarder has reverse self-locking function, common RV retarder under certain condition can
Reverse self-locking, common harmonic speed reducer do not have reverse self-locking function.If retarder has reverse self-locking function, electric motor circuit breaking
The opposing torque of back loading device cannot drive retarder generate displacement, avoid because it is uncontrollable displacement caused by collide, fall with
And other accidents.
If having the advantages that, a kind of deceleration mechanism is big with transmission ratio, output torque is big, which does not have flexible gear,

Degree is equal to the difference of one rotation speed of two rotation speed of bi-bevel gear and bi-bevel gear.Planet stent Forward to slow down direction of rotation and double
Two Forward to slow down direction of rotation of bevel gear is identical, and planet stent drives output shaft slow-speed of revolution rotating Vortex by planet axis.
The deceleration mechanism reversely run slowly state when, motor by input shaft drive input bevel gear around input
Axis axis is rotated along input shaft Forward to slow down direction of rotation opposite direction, and input bevel gear driving bi-bevel gear one is around output
Axis axis is rotated along the direction that is reversely rotated in deceleration of bi-bevel gear one, and at the same time, input bevel gear driving bi-bevel gear two is enclosed
It is rotated around output shaft axis along the direction that is reversely rotated in deceleration of bi-bevel gear two, at this point, one direction of rotation of bi-bevel gear and bipyramid
Two direction of rotation of gear on the contrary, and the factor of few teeth difference one make one rotation speed of bi-bevel gear and two rotation speed of bi-bevel gear
Unequal, if two rotation speed of bi-bevel gear is greater than one rotation speed of bi-bevel gear, bi-bevel gear one and bi-bevel gear two are common
Driving bevel planet gear is reversely rotated in deceleration direction rotation around planet axis axis along bevel planet gear, in order to offset the speed
Difference, bevel planet gear can also revolve around output shaft axis, and bevel planet gear drives planet stent slow-speed of revolution rotation, planet stent
Rotation speed is equal to the difference of one rotation speed of two rotation speed of bi-bevel gear and bi-bevel gear.The reversed side of being rotated in deceleration of planet stent
To being reversely rotated in deceleration with bi-bevel gear two, direction is identical, and planet stent drives the output shaft slow-speed of revolution to revolve in the same direction by planet axis
Turn.
When the deceleration mechanism reverse self-locking state, electric motor circuit breaking, the opposing torque that load device generates makes output shaft
There is rotating tendency, opposing torque passes sequentially through output shaft, planet axis, planet stent, bevel planet gear and respectively drives bi-bevel gear
One and bi-bevel gear two, torque direction one and anti-when opposing torque drives the reverse self-locking of bi-bevel gear one by bevel planet gear
Torque direction two is identical when driving the reverse self-locking of bi-bevel gear two by bevel planet gear to torque, bi-bevel gear one and bipyramid
The input shaft of driving input shaft component and input bevel gear rotate gear two around output shaft axis jointly, due to input shaft component
Input shaft and input bevel gear only surround input shaft axis rotation one degree of freedom, input shaft and input bevel gear prevent
Opposing torque drives the deceleration mechanism rotation, realizes deceleration mechanism reverse self-locking.
The deceleration mechanism does not include flexible gear, and the few teeth difference differential generator of the deceleration mechanism makes bi-bevel gear one
Rotation speed and two rotation speed of bi-bevel gear are unequal, in deceleration mechanism operational process, by few teeth difference differential generator
Drive bipyramid tooth planetary reducer, the output shaft revolving speed and one revolving speed of bi-bevel gear and bi-bevel gear two of the deceleration mechanism
The difference of revolving speed is related, has the advantages that transmission ratio is big, output torque is big, long service life.The deceleration mechanism have it is reversed from
Lock function.
