As shown in Figures 1 to 6, a kind of system that can test output shaft assembly frictional force, including test fixture 21 and rub
Wipe power test suite 22；Test fixture 21 includes main body, shaft 212, turntable 213 and handle 214；Shaft 212 is arranged at main body,
Turntable 213 is positioned over main body, the axial line of the Plane of rotation of turntable 213 perpendicular to shaft 212；Shaft 212 is adjacent to turntable 213
Blind hole is set in one end；Handle 214 is connected with turntable 213, is rotated with turntable 213；Turntable 213 is through 11 band of tested output shaft assembly
Shaft 212 to rotate；Friction testing component 22 includes electronic scale 221 and connecting rope 222；The hook 2211 of electronic scale 221 passes through
Connecting rope 222 is connected to shaft 212.The system can accurately measure the friction value of output shaft assembly 11, then matching strip
Movable property product work, and avoid the occurrence of technical problem.
The main body of the present invention includes base 2111 and stent 2112,2111 bearing support 2112 of base.Stent 2112 is used for
Fixed rotating shaft 212.Stent 2112 is fixed on base 2111.
The turntable 213 of the present invention has internal gear, and internal gear is total to axial line with shaft 212, and turntable 213 can with internal gear
For integral type, alternatively, the turntable 213 includes toothed disc, internal gear is set, toothed disc, which coordinates, is positioned over turntable 213 in toothed disc
Centre bore.The internal gear is used to be engaged with the gear 112 of tested output shaft 111, so as to fulfill 214 driving disc of handle
It can be rotated when 213 with gear 112, gear 112 rotates to be rotated with output shaft 111.
The present invention sets a connecting hole 2121 in the outer wall of shaft 212, for one end of fixed connection string 222, Ji Jianglian
Bind the connecting hole 2121 in one end of splicing 222.The connecting rope 222 can be nylon rope.
The both ends of shaft 212 of the present invention set a bearing 215 respectively, for carrying shaft 212, when output shaft 111 stretches into
In the blind hole of shaft 212, rotated by output shaft 111 with shaft 212.The bearing 215 can reduce resistance.
As shown in Figures 1 to 6, the present invention provides a kind of method that can test 11 frictional force of output shaft assembly, it is applied
In above-mentioned system；This method comprises the following steps：Preparation output shaft assembly 11 to be tested, the output shaft assembly 11 include producing
Axis and it is arranged gear 112, friction plate 113 thereon；Output shaft assembly 11 is placed in test fixture 21, i.e., gear 112 is with turning
The blind hole of shaft 212 is stretched into the internal gear engagement of disk 213, output shaft 111；Electronic scale 221 is through 222 connection rotating shaft 212 of connecting rope；
The handle 214 drives the turntable 213 to rotate, the friction value shown by the electronic scale 221.
The operation principle of present system is：By test fixture 21 by the gear 112 and output shaft of output shaft assembly 11
111 engage respectively, and by the internal gear meshing gear 112 of turntable 213, which can protect gear 112 injury-free, together
When drive gear 112 rotate, by the power that rotate gear 112 needs by being had on nylon rope transfer reaction to electronic scale 221
Body numerical monitor.When turntable 213 goes to certain angle, nylon rope produces certain pulling force to electronic scale 221, when pulling force is more than defeated
When going out 11 frictional force of shaft assembly, 111 frictional force of output shaft can fail produce slipping phenomenon, at this time electronic scale 221 show numerical value with
111 frictional force of output shaft is cancelled out each other, at this time as current 11 friction force value of output shaft assembly.
During test, electronic scale 221 is fixed, nylon rope one end and electronic scale 221 hook 2211 be connected, the other end and
The rotation axis connection of test fixture 21, during rotational handle 214, rotation axis can rotate.The nylon rope being connected accordingly with rotation axis
It can be wound on the rotating shaft as rotation axis rotates.Correspondingly, the nylon rope other end can pull electronic scale 221 to link up with 2211,
When 221 reading of electronic scale is steady, i.e., currently test the friction force value of output shaft assembly 11.Before testing, electronic scale 221 is necessary
Zero.
Following table is one group of test data, frictional force specification:(1.9-2.25kgf.cm)
| #1 | 2.01 | #6 | 2.03 |
| #2 | 2.11 | #7 | 2.07 |
| #3 | 1.25NG | #8 | 1.98 |
| #4 | 1.99 | #9 | 3.01NG |
| #5 | 2.15 | #10 | 2.20 |
#3：When frictional force is 1.25kgf.cm, less than specification, when the torque for driving product and needing is more than frictional force,
111 torque of output shaft deficiency, 111 skidding NG. of output shaft
#9：When frictional force is 3.01kgf.cm, higher than specification, when output shaft 111 is acted on excessive by external force, output shaft
111 frictional force fail, and can not cause to skid so as to protect gear 112, gear 112 easily crumbles, and output shaft 111 beats tooth NG.
The friction value of method test output shaft assembly 11 using the present invention, then matches the product being attached thereto,
Alternatively, by matched connection product demand, the stitching state of output shaft assembly 11 is adjusted, corresponding frictional force number is obtained until testing
The output shaft assembly 11 of value.Enable output shaft assembly 11 to match multiple product demand, and eliminate the skill for playing tooth or skidding
Art problem.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
