Problems solved by technology

Existing performance testing devices can measure types and specifications are relatively fixed, and the load range is low, which can no longer meet the needs
Most of the test devices are fixed platforms, and the installation process is complicated. When testing multiple planetary roller screws, multiple disassembly and assembly are required, which wastes time and destroys the overall accuracy of the test device. It is difficult to guarantee a single variable

Abstract

The invention relates to a testing device for a 15t-level planetary roller screw, which belongs to the field of high-loading and high-rigidity transmission performance testing. ;The movable sliding table, the clamping device, the tension and pressure sensor group, and the braking device are all arranged on the upper surface of the base; the axial direction of the screw to be tested is horizontally arranged in the clamping device; the axial direction of the screw to be tested is along the long side of the base The movable sliding table, the clamping device, the tension and pressure sensor group, and the braking device are placed in sequence along the axis of the screw to be tested; the output end of the movable sliding table is connected to the screw to be tested; one end of the axial direction of the screw to be tested It is fixedly installed on the clamping device; one end of the clamping device is butted with one end of the tension and pressure sensor group; the other end of the tension and pressure sensor group is butted with the braking device; the invention is suitable for various types and specifications of planetary roller screws, Meet the test requirements of large load and high precision, simplify the card installation process, and maintain the accuracy of the platform during multiple disassembly and assembly processes.

Description

technical field [0001] The invention belongs to the field of high-loading and high-rigidity transmission performance testing, and relates to a testing device for a 15t-level planetary roller screw. Background technique [0002] After years of research and development, the existing domestic planetary roller screws have the characteristics of various types, multiple specifications, wide bearing range and high precision level, which can cope with various application occasions and expand the application scope of planetary roller screws. The types and specifications of the existing performance testing devices are relatively fixed, and the bearing range is low, which can no longer meet the needs. Most of the test devices are fixed platforms, and the clamping process is complicated. When testing multiple planetary roller screws, multiple disassembly and assembly are required, which wastes time and destroys the overall accuracy of the test device, making it difficult to guarantee a ...
