In the utility model, the inner ring pushing body, the platform can be replaced according to bearings of different types, therefore, a lot of materials are saved, the most important is that the rotating precision of the bearing is increased, and the vibration is reduced.
Description
Technical field:
The utility model relates to a kind of measurement mechanism, specifically is the device of a kind of measured angular contact ball bearing deflection under pretightning force.
Background technology:
Along with the continuous development of lathe, machine tool accuracy and serviceable life are had higher requirement towards high precision, high-level efficiency, high automation and heavy-duty, maximization direction.Angular contact ball bearing has a wide range of applications on lathe, angular contact ball bearing when mounted, the spacer control pretightning force of being everlasting and adding uniform thickness not between two bearings allows bearing work under negative play.Like this, can improve the running accuracy of bearing, reduce vibration, also can improve the rigidity of bearing simultaneously.But owing to there are differences between each bearing, the spacer thickness that needs also is not quite similar, and common way is to survey in installation process, but this has reduced installation effectiveness, how just to choose the approach that suitable spacer is the raising installation effectiveness before installing.
Summary of the invention:
Technical matters to be solved by this invention provides a kind of device that can determine the deflection of angular contact ball bearing under specified pretightning force condition before installation, can select the spacer of suitable thickness by this device.
For achieving the above object, the device of measured angular contact ball bearing described in the utility model deflection under pretightning force, comprise rigid support, platform, inner ring pushes away body, the U-shaped body, the thrust body, push rod and hand lever, described rigid support comprises base and the extended load of base upper lateral portion, platform is installed in and is used to place bearing to be measured on the base, the inner ring corresponding with the bearing inner race size pushes away on the inner ring that body is placed on bearing, the U-shaped body that ballast power and decrement corresponding relation are known is horizontal to be pushed away on the body at inner ring, the U-shaped body is provided with the survey table of measuring U-shaped body decrement, be pressed with the thrust body on U-shaped body top, push rod is installed in by being threaded in the load portion of rigid support, the bottom of push rod contacts with thrust body end face, and the hand lever level that is used to rotate is installed in the push rod top.
Base as an improvement platform of the present utility model and rigid support can be one.
Principle of work: operating personnel drive the rotation of thrust body by hand lever and push rod, and then compress the U-shaped body, the U-shaped body begins distortion immediately, because ballast power and decrement corresponding relation are known, when the survey table swings to specified numerical value, also promptly be applied on the bearing and be specified pretightning force, the difference of the Internal and external cycle by recording bearing this moment more then, thus draw needed spacer thickness.
This device can be according to the bearing of different model, change inner ring and push away body, platform, has good versatility, saved wide variety of materials, the most important thing is to improve the precision of machine tool motion, alleviate labor intensity of operating personnel, improved work efficiency greatly, saved a large amount of lathe manufacturing costs.Have simple in structure, easy to operate, cost is low, measure characteristic of accurate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure, measurement mechanism described in the utility model comprises that mainly rigid support, platform 1, inner ring push away body 2, U-shaped body 3, thrust body 4, push rod 5 and hand lever 6, wherein;
Rigid support is made up of base 7 and the extended load of base upper lateral portion 8.Platform 1 is installed on the base 7, is used to place bearing 9 to be measured.Inner ring pushes away on the inner ring that body 2 is placed on bearing 9, according to the bearing different size, needs the inner ring of different model to push away body 2.U-shaped body 3 is horizontal to be pushed away on the body 2 at inner ring, needs to measure before the ballast power of this U-shaped body 3 and the decrement corresponding relation.U-shaped body 3 is provided with the survey table 10 of measuring U-shaped body 3 decrements, be pressed with thrust body 4 on U-shaped body 3 tops, push rod 5 is installed in by being threaded in the load portion 8 of rigid support, and the bottom of push rod 5 contacts with thrust body 4 end faces, and hand lever 1 level that is used to rotate is installed in push rod 5 tops.Platform 1 can be one with the base 7 of rigid support.
The utility model is not having under the situation of combo at angular contact ball bearing, how to determine that between two bearings the spacer that adds suitable thickness controls pretightning force, the problem that allows bearing under negative play, work, a kind of simple, easy to operate, the specified pretightning force of measured angular contact ball bearing and the device of deflection relation accurately are provided, and then the thickness difference of definite interior outer separator, can improve the running accuracy of bearing like this, reduce vibration.Also can improve simultaneously the rigidity of bearing.
Concrete application approach of the present utility model is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
