Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0013] Such as figure 1 As shown, the bottom plate 1 is preferably a rectangular flat plate. A vertical fixed plate 2 is installed on the bottom plate 1. The vertical fixed plate 2 is perpendicular to the bottom plate 1. The top of the vertical fixed plate 2 is bent to form a horizontal suspension plate. The precision servo The top of the cylinder body of the electric cylinder 3 is attached to the bottom surface of the horizontal suspension plate, and the precision servo electric cylinder 3 is fixedly connected with the horizontal suspension plate through screws, so that the precision servo electric cylinder 3 is suspended and installed on the vertical fixed plate 2 .
[0014] Such as figure 1 As shown, the output shaft of the precision servo electric cylinder 3 protrudes vertically downwards, and is threadedly connected with the upper end of the pressure se...

The invention discloses a deep groove ball bearing stiffness testing device. A precision servo electric cylinder is suspended at the top of a vertical fixing plate; an output shaft of the precision servo electric cylinder is connected with the upper end of a pressure sensor; a loading screw is mounted at the bottom of the pressure sensor; a measuring plate is placed horizontally; a mounting end ofthe measuring plate sleeves the loading screw; a precision displacement sensor is arranged beside the pressure sensor; a measuring head of the precision displacement sensor is in contact with the topsurface of a suspended end of the measuring plate; a supporting shaft is arranged below the measuring plate; the two ends of the supporting shaft are supported by two V-shaped modelblocks respectively; the bottom of each V-shaped block is fixed on a bottom plate through a connecting plate. The testing device disclosed by the invention simulates the loading working condition of an actual vehicle,and can provide guidance data for product optimization, through deep groove ball bearing stiffness test and data analysis. The device disclosed by the invention has the advantages of simple structure,easiness in implementation, convenience in testing operation and accurate and reliable testing result, and is applicable to the stiffness test of various types of deep groove ball bearings, and has strong universality.
Description
technical field [0001] The invention relates to a deep groove ball bearing rigidity detection device, which is used for rigidity detection of deep groove ball bearings of automobile gearboxes. Background technique [0002] Deep groove ball bearings are the most representative rolling bearings and are widely used. Suitable for high or even very high rpm operation, they are extremely durable and require little maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and easy to achieve high manufacturing precision. Deep groove ball bearings vary in size and form, and are used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery. They are the most widely used type of bearings in the machinery industry. [0003] At present, the bearings used in automobile gearboxes are mostly deep groove ball bearings, which mainly bear radial loads and can also bear a certain amount of ax...
