Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only of the invention
A part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Below in conjunction with attached drawing, the technical solution of embodiment that the present invention will be described in detail offer.
The embodiment of the invention provides a kind of distance-limiting type retarders, as shown in Figure 1 and Figure 2, comprising: cabinet 1, transmission
Component I and output precision II.Output precision II includes: shell 2 and the first support base 3, second inside shell 2
Support seat 4, sun gear 5, ring gear 6, planet carrier 7, spline housing 8 and friction Xian Ju mechanism 9.Shell 2 is connect with cabinet 1, transmission group
Part I is located in cabinet 1, and one end is connect with motor output end, and the other end is connect with sun gear 5, and sun gear 5 is driven to rotate.First
Support base 3 is fixed on cabinet 1, and the second support base 4 is disposed around outside the first support base 3, and friction Xian Ju mechanism 9 is located at the first support
Between seat 3 and the second support base 4 and the inner wall with the outer wall of the first support base 3 and the second support base 4 offsets respectively, for providing
Frictional force transmitting torque keeps the second support base 4 and the first support base 3 relatively fixed；Rub Xian Ju mechanism 9 and the first support base 3 and
Frictional force between second support base 4 is adjustable.Ring gear 6 is connect with the second support base 4, and planet carrier 7 is connect with spline housing 8.Too
When sun wheel 5, planet carrier 7 and ring gear 6 constitute planetary gear train, the first support base 3 and relatively fixed the second support base 4, sun gear 5
It drives planet carrier 7 to rotate, passes through 8 output torque of spline housing；When first support base 3 and the second support base 4 skid, planet carrier 7 stops
Rotation stop is dynamic, and sun gear 5 drives ring gear 6 and the rotation of the second support base 4.
The working principle of distance-limiting type retarder provided in an embodiment of the present invention is illustrated below:
In use, transmission component I is connect with motor output shaft, the output torque of motor drives the sun by transmission component I
5 rotation of wheel, sun gear 5, planet carrier 7 and ring gear 6 constitute planetary gear train, it is to be understood that are set with planet on planet carrier 7
Wheel, planetary gear engage between planet carrier 7 and ring gear 6 and respectively with sun gear 5 and ring gear 6.Ring gear 6 is arranged to
When fixed, sun gear 5 is rotated, and is revolved while driving planetary gear rotation along sun gear 5, and then planet carrier 7 is driven to rotate.
When planet carrier 7 can not rotate, planetary gear rotation is driven when sun gear 5 rotates, and then ring gear 6 is made to rotate.Based on above-mentioned,
First support base 3 and the second support base 4 are linked by the frictional force for the Xian Ju mechanism 9 that rubs, what which can transmit
Peak torque is slipping torque.When impact moment between first support base 3 and the second support base 4 is less than slipping torque, second
Support base 4 is fixed, that is, ring gear 6 is arranged to fixed, and sun gear 5 drives planet carrier 7 to rotate, and passes through spline housing 8
Outside output torque is at this time normal operating conditions.When blocking phenomenon occurs, planet carrier 7 and spline housing 8 can not be rotated, and second
Impact moment between support base 4 and the first support base 3 increases, when impact moment is greater than or equal to slipping torque, the second support
Seat 4 and the opposite skidding of the first support base 3, sun gear 5 passes through planetary gear drive ring gear 6 at this time and the second support base 4 rotates.It is logical
It crosses and sets slipping torque to slightly larger than the torque (for example, can be 3 times under normal operating conditions) worked normally under state, it can
Guarantee to work normally the torque transmitting under state, and can skid when phenomena such as stuck occurs, avoids generating biggish torque
Cause motor and/or equipment to damage, improves production safety performance.And friction Xian Ju mechanism 9 will not damage during skidding,
It can normally come into operation after equipment troubleshooting without manual reversion.Further, due to friction Xian Ju mechanism 9 and the
Frictional force between one support base 3 and the second support base 4 is adjustable, and different frictional force corresponds to different slipping torques, Ke Yiman
The limit square use demand of sufficient different scenes, the scope of application are wider.
As it can be seen that distance-limiting type retarder provided in an embodiment of the present invention, make the by the frictional force that friction Xian Ju mechanism 9 provides
Two support bases 4 and the first support base 3 are relatively fixed, not only can guarantee the torque transmitting worked normally under state, but also blocking can occur
Etc. failures when realize skid limit square function, play a protective role to motor, transmission device or equipment etc., improve complete machine can
By property.It is adjusted by the frictional force to friction Xian Ju mechanism 9, can satisfy the use demand of different scenes, the scope of application
It is relatively wide.Due to friction, Xian Ju mechanism 9 is hardly damaged during skidding, and manual reversion is not necessarily to after equipment troubleshooting
It quickly goes into operation, increases economic efficiency.
