Description
Technical field
The present invention relates to friction coefficient measurement technical field, be specially a kind of confficient of static friction detector.
Background technology
Since the domestic appearance of hydrocoupling in 1995, the coefficient of friction one between hydrocoupling inner sleeve and axle
Directly taking 0.14 ~ 0.15, be developed so far my company and coefficient of friction between the two can be got about 0.25, current world standard is
0.3, it is the important indicator of product for the coefficient of friction of hydrocoupling, especially confficient of static friction, therefore measure product
Coefficient of friction is also an important problem, to process modification and Quality advance offer strong guarantee, and existing measuring method
Be typically all torque value to retrodict calculatings, along with the requirement of hydrocoupling is being promoted by market, it is desirable to the static friction of high pressure with
Dynamic friction testing stand there is no, only for the lowest small-scale test instrument of unit pressure of teaching, as DVTTM-1,
MXD-0, and for high pressure test such as 40 to 120MPa, then there is no such detecting instrument.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of confficient of static friction detector, its simple in construction, it is possible to convenient
The coefficient of friction detected under high pressure.
Its technical scheme is such that a kind of confficient of static friction detector, it is characterised in that it includes body, described
Internal portion has measurement cavity, is provided with the first pairing test block, the described first pairing test block left and right sides in described measurement cavity
It is provided with one second pairing test block, is provided with, on front side of described first pairing test block, the pushing tow promoting described first pairing test block
Oil cylinder, is provided with the amount post of contact on rear side of described first pairing test block, described amount post is provided with a table, described first pairing examination
Block lower end is supported on ball, described body is additionally provided with described pipe bending cylinder be mutually perpendicular to arrange compressed oil cylinder, institute
Stating compressed oil cylinder promotes one piece of described second pairing test block to make described first pairing test block be pressed in described second pairing test block
In described measurement cavity.
It is further characterized by, and described pipe bending cylinder and described compressed oil cylinder are all fixedly installed in described by screw
On body, described pipe bending cylinder all stretches into described measurement cavity by perforation with the piston rod of described compressed oil cylinder；
Described first pairing test block lower end is supported on two described balls；
Before and after described second pairing test block, two sides distance is corresponding with the width of described measurement cavity, described first pairing test block
The width of described measurement cavity it is less than for square and the length of side.
After using the detector of the present invention, compressed oil cylinder applies a method by the second pairing test block to the first pairing test block
To loading force, pipe bending cylinder applies a thrust to the first pairing test block thus in the first pairing test block and the second pairing test block
Produce direction frictional force on contact surface, i.e. can get the first pairing test block and second by the ratio of frictional force Yu normal load power
Coefficient of friction between pairing test block, overall structure is simple, require according to high pressure the thrust that can adjust compressed oil cylinder from
And change the jacking force of pipe bending cylinder, detect the coefficient of friction under high pressure easily；Two sides before and after second pairing test block
The distance guiding that can ensure that when second pairing test block move corresponding with the width measuring cavity is accurate, it is ensured that the essence of measurement
Degree.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 be in Fig. 1 A-A to sectional view；
Fig. 3 is left view of the present invention.
Detailed description of the invention
Seeing Fig. 1, shown in Fig. 2, Fig. 3, a kind of confficient of static friction detector, it includes that body 1, body 1 inside have measurement
Cavity 2, is provided with the first pairing test block 3 in measuring cavity 2, first pairing test block 3 left and right sides is provided with one second and joins
To test block 4, it is provided with the pipe bending cylinder 5 promoting the first pairing test block 3 on front side of the first pairing test block 3, on rear side of the first pairing test block 3
It is provided with the amount post 6 of contact, amount post 6 is provided with a table (not shown), whether changes can judge by the reading of silk table
Whether the first pairing test block 3 moves, and the first pairing test block 3 lower end is supported on two balls 7, and the setting of ball 7 makes first to join
It is rolling friction to test block 3 bottom surface, substantially can ignore this frictional force, thus ensure that the thrust recorded is compressed oil cylinder 8 and executes
The thrust added and the frictional force produced, body 1 is additionally provided with and is mutually perpendicular to the compressed oil cylinder 8 arranged, pressure with pipe bending cylinder 5
Locking oil cylinder 8 promotes one piece of second pairing test block 4 to make the first pairing test block 3 and the second pairing test block 4 be pressed in measurement cavity 2.
Pipe bending cylinder 5 and compressed oil cylinder 8 are all fixedly installed on body 1 by screw 9, pipe bending cylinder 5 and the piston rod of compressed oil cylinder 8
10 all stretch into measurement cavity by perforation；Before and after second pairing test block 4, two sides distance is corresponding with the width measuring cavity 2,
First pairing test block 3 is the width that square and the length of side are less than measurement cavity 2.In figure, 12 is the joint of releasing of oil cylinder.
Measurement process is as described below: compressed oil cylinder 8 applies a thrust set to the second pairing test block 4 on right side to be made
First pairing test block 3 is pressed between two second pairing test blocks 4, and then the piston of pipe bending cylinder 5 withstands the first pairing examination
Block 3 applies thrust to it, and now the first pairing test block 3 remains static, and the first pairing test block 3 matches test block 4 with second
Produce stiction between contact surface, be gradually increased thrust, until the first pairing test block 4 from static to that time of movement, stop
Only adding high thrust, thrust now is maximum static friction force, owing to the first pairing test block about 4 two sides is all tried with the second pairing
Block 5 contacts, and the maximum static friction force recorded is confficient of static friction divided by the thrust of twice.
