Abstract

The invention discloses novel tapered roller bearing play regulating equipment and a regulating method of the novel tapered roller bearing play regulating equipment and belongs to the technical field of engineering mechanical gearboxes. The novel cone tapered roller bearing play regulating equipment comprises a pressure regulating system, a measuring system and a correction table dial. A pneumatic hydraulic pump in the pressure regulating system is connected with a manual reversing valve through an oil pipeline. The manual reversing valve is respectively connected with a first pressure relieving valve and a second pressure relieving valve through oil piplines. The first pressure relieving valve and the second pressure relieving valve are respectively connected with a shuttle valve through oil pipelines. A pressure gauge is arranged on the shuttle valve. An oil cylinder in the measuring system is connected with the shuttle valve through the oil pipeline and acts on a pressure cover. Dial indicators are installed in preserved holes of an end cover of a bearing. A to-be-regulated device is regulated through a high-pressure oil line of the pressure regulating system and read through a low-pressure oil line to obtain dial indicator values. An average of the values measured by the two dial indicators is worked out so that a final bearing play value which is needed can be ensured by regulating thickness of a cushion piece. The novel tapered roller bearing play regulating equipment is mainly used for regulating a tapered roller bearing play.
