The invention discloses a loading device for a bearing test of a high speed railway. The loading device for the bearing test of the high speed railway comprises a base part, a transmission part and a loading part. The base part is provided with a variable frequency motor, a bearing and two supporting bearings. The two supporting bearings are respectively provided with test main shafts. Both ends of each test main shaft are respectively provided with a tested bearing. The variable frequency motor of the transmission part is connected with a belt wheel shaft which is provided with two V-shaped belts simultaneously. The other ends of the V-shaped belts are sleeved on two driven wheels toward both sides. The two driven wheels are respectively installed on the two test main shafts. According to the device provided by the invention, the loading system is in a manner that a hydraulic transmission and a force-amplifier are combined, so that the input force of the loading system is effectively reduced, the system is high in reliability and small in power consumption, and the test efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a high-speed railway bearing test loading device. Background technique [0002] High-speed railway bearings require high-speed, heavy-load and high-reliability performance. In order to evaluate the reliability of high-speed railway bearings, it is necessary to conduct experimental research on the dynamic performance of high-speed railway bearings during actual operation. [0003] At present, there are few domestic studies on the test loading of high-speed railway bearings, and the test devices for high-speed and heavy-duty bearings basically adopt a simple hydraulic loading method, resulting in bulky test devices and high power consumption. cause liquid to leak easily. [0004] At the same time, the existing bearing loading device also has the following problems: (1) Since the test cycle of the bearing performance test, especially the life reliability test, is very lo...
