Description
【Technical field】
This utility model belongs to the technical field of load sensor, specifically refers to the thrust articulated bearing knot of load sensor
Structure.
【Background technology】
In recent years, as the measurement of the fast development of China's industrial level, force value and quality is in highway, high-speed iron
The fields such as road, large bridge, skyscraper, metallurgy and Aero-Space are more and more extensive, as measurement working sensor and
The standard transducer of transmission of quantity value, the demand of load sensor constantly increases.The research and exploitation for carrying out load sensor should
With, the quality of load sensor is improved constantly, strong guarantee can be provided for the sustained and rapid development of industry, with considerable
Economic benefit and far-reaching social benefit.
Bulb is the important component part of load sensor, and external applied load passes to elastomer by bulb, therefore bulb can
The load distribution of adjustment sensor elastomer, reduces parasitic component（Side force and additional moment）Impact to sensor, improves
The metering performance of sensor.For example, when examining and determine load sensor using force standard machines, because the upper following table of loom work can not be protected
Card is absolute parallel, if not adopting bulb, load distribution on a sensor will appear from unbalance loading phenomenon, so as to generate big showing
Value error and azimuthal error, have impact on the linear and repdocutbility of sensor.After using bulb, in loading procedure, bulb is by root
According to the situation and deformation of table top, self-adaptative adjustment is carried out, be distributed the load on sensor elastomer more uniform, reduced
The impacts of frame geometrical issues and insufficient rigidity to sensor performance.
The reasonability and its production quality of bulb design are directly connected to the metering performance and service life of sensor, especially
It is the standard dynamometer for class of accuracy more than 0.3 grade, the effect of bulb is particularly important.Bulb design with
There are problems that in the course of processing it is substantial amounts of, different ranges, the load sensor of different structure need different structure, different size,
The bulb of different contact forms, in process, material, Technology for Heating Processing, mechanical processing technique are required for rational selection
With compile and edit, for contact surface fatigue and wear-out failure the need for in-depth study explore.
Prior art is as shown in figure 1, the thrust articulated bearing of load sensor, including the He of bulb 1 of mutual floating connection
The longitudinal axis of ball bowl 2, bulb 1 and ball bowl 2 coincides, and the central spot of bulb 1 and ball bowl 2 passes through the floating connection of pin 3.For little power
The load sensor better performances of value, but be used in that self-locking and insufficient rigidity occurs during great force value sensor, have a strong impact on
The performance of sensor, so that the effect failure of bulb.
At present, it is very few for the research of load sensor bulb, more not to involved by bulb design and the course of processing
And problem goed deep into systematic research excessively, often by virtue of experience, in use Jing often occurs in that self-locking, rigidity for design
The problems such as not enough, fatigue and wear-out failure, the use of bulb is had a strong impact on, the effect for making bulb is failed.
【The content of the invention】
Technical problem to be solved in the utility model is the thrust articulated bearing structure for providing a kind of load sensor,
By the improvement to ball head structure, the load distribution of sensor elastomer is adjusted, reduce parasitic component（Side force and additional force
Square）Impact to sensor, improves the metering performance of sensor.
What this utility model was realized in：
The thrust articulated bearing structure of load sensor, including bulb, ball bowl；The central spot of the bulb and ball bowl is led to
Pin floating connection is crossed, is positioned；It is characterized in that：A circle groove is opened up in the middle part of the ball bowl, is provided with many in the groove
The individual universal ball bearing with regulation spring, touches with the bottom connection of the bulb.
Further, it is the plurality of to be evenly provided in the groove with the multi-directional ball bearing spacer for adjusting spring.
The utility model has the advantage of：1st, the structure, when not loading, is rolling friction between bulb and ball bowl, bulb
Rolling resistance is little, in the case where gravity is adjusted, can be with automatic adjustable level；2nd, the structure is in the loading starting stage, bulb and ball bowl it
Between be rolling friction, bulb rolling resistance is little, bulb according to the parallel condition for loading working face, carry out self regulation；3、
After being loaded into certain load, multi-directional ball is pressed into ball bowl, bulb and ball bowl plane-plane contact, large carrying capacity；4th, after unloading, bulb
By the spring force jack-up of multi-directional ball, can prevent bulb from boning with ball bowl and causing subsequently to work on.

【Specific embodiment】
As shown in Figures 2 to 5, the thrust articulated bearing structure of load sensor, including bulb 1, ball bowl 2；The bulb 1
Pass through the floating connection of pin 3 with the central spot of ball bowl 2, positioned；The middle part of the ball bowl 2 opens up a circle groove 21, described
It is provided with multiple with the universal ball bearing 4 for adjusting spring in groove 21, touches with the bottom connection of the bulb 1.
Wherein, it is multiple to arrange evenly and at intervals in the groove 21 with the universal ball bearing 4 for adjusting spring.
This utility model application contact mechanics theory, tribology theory and abrasion analysis, for load sensor bulb
Conduct a research the problems such as design is with structure present in production process, material, Technology for Heating Processing and mechanical processing technique, propose
Solution, improves the design theory of load sensor bulb, improve product quality.
Structure of the present utility model, when not loading, is rolling friction between bulb 1 and ball bowl 2, the rolling resistance of bulb 1
It is little, in the case where gravity is adjusted, can be with automatic adjustable level；The structure, in the loading starting stage, is rolling between bulb 1 and ball bowl 2
Friction, bulb rolling resistance is little, and bulb 1 carries out self regulation according to the parallel condition with loading working face；It is loaded into certain
After load, the multi-directional ball with the universal ball bearing 4 for adjusting spring is pressed into ball bowl 2, bulb 1 and the plane-plane contact of ball bowl 2, carries
Ability is big；After unloading, bulb 1 can prevent bulb 1 from boning and causing subsequently cannot with ball bowl 2 by the spring force jack-up of multi-directional ball
Work on.
