Summary of the invention
The utility model provides a kind of right rolling bearing running-in machine of railway freight-car wheel that is used for, and it is low to have consumption of power, and the friction wheel wearing and tearing are few, the advantage that security is good.
The utility model be achieved in that it comprise support, be fixed on the support be used for support wheel guide rail and be used for the right top wheel oil cylinder of lifting wheel, the running-in machine that wheel carried out break-in to last rolling bearing with and be used for detecting the infrared thermometer of rolling bearing temperature, running-in machine is symmetricly set on the support two ends; Each running-in machine comprises motor, gearing and friction drive wheel, motor, gearing and friction drive wheel are fixed on the rotary support, the rotary support outer end is connected with frame on being fixed on support by rotating shaft, the inner is supported on the frame, when wheel to by top wheel oil cylinder jack-up to the right rolling bearing of working position hour wheel with friction drive wheel jack-up, make the weight that rotary support the inner is born be applied on the rolling bearing by friction drive wheel; Infrared thermometer is fixed on the rotary support by mounting rail.The deadweight of dependence running-in machine, roll extrusion friction wheel and rolling bearing shell be flexible contact and drives the rolling bearing rotation, and wheel does not participate in rotating to outer other parts of rolling bearing only, and workpiece object participation rotating weight alleviates greatly, so consumption of power reduces greatly, the friction wheel wearing and tearing also significantly reduce.
In order to increase friction force, each running-in machine is provided with two friction drive wheels with fast equidirectional rotation at least.
Right for the wheel that can be fit to different size, support is provided with the guide rail of several different gauges; Have at least the frame and the support of an end running-in machine to be slidingly connected, support is provided with the regulating device of regulating described frame displacement.By regulating the position of frame on support, can be fit to different gauge wheels to the rolling bearing break-in.
Running-in machine of the present utility model and frame flexibly connect, and running-in machine relies on deadweight and rolling bearing shell flexibility to contact, and workpiece object participates in rotating weight and alleviates greatly, so consumption of power reduces greatly, the friction wheel wearing and tearing also significantly reduce; The frame and the support of running-in machine are slidingly connected, and can regulate displacement according to different gauges, and the wheel that can be fit to different size is to the rolling bearing break-in, and the versatility of equipment is improved.
