Abstract

The invention relates to the technical field of reducers, and provides a gear pump and a reducer. The gear pump includes a pump body, a gear set, a pressure regulating valve and a safety valve; a pump cavity is arranged inside the pump body; the gear set is arranged in the pump body, and the gear set divides the pump cavity into a suction side and a discharge side; the pressure regulating valve is set on the pump body, and the opening of the pressure regulating valve communicates with the discharge side; the safety valve is arranged on the pump body, and the opening of the safety valve communicates with the discharge side. The safety of the whole system is ensured by the pressure regulating valve and the safety valve.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a gear pump and a reducer equipped with the gear pump. Background technique [0002] At present, the gear pump consists of parts such as driving gear, driven gear, pump body and pump cover. Its working principle is that when the teeth on the suction side mesh out, the volume of the suction side chamber increases and the pressure decreases, and lubricating oil enters the suction side chamber and enters the discharge side chamber along with the gear teeth. When the discharge side gear engages, the volume of the discharge side chamber decreases, the pressure increases, and the lubricating oil is discharged. When starting at low temperature, the gear pump is prone to problems such as excessive lubricating oil pressure and excessive starting power, which may lead to breakage of the drive shaft; The pressure inside is too high, causing the pipe to burst. [0003] Therefore, it is n...
