The invention discloses a gear oil pump with good stability. The gear oil pump comprises a pump body, a pump cover, an inner gear, an outer gear and a transmission shaft. The gear oil pump is characterized in that the middle part of the transmission shaft is in interference connection with the outer gear, and the transmission shaft and the inner gear are arranged in a gear hole and shaft holes of the pump body and the pump cover in a complete set; a crescent isolation plate is arranged in an eccentric distance space formed by the outer gear hole and the inner gear hole of an inner cavity of the pump body, and an arc-shaped rubber pad used for sealing is arranged on the upper part of the crescent isolation plate; the inner arc line of the isolation plate is precisely and movably matched with the top circle of the outer gear to prevent engine oil in a tooth cavity of the outer gear from leaking out and convey the engine oil from the oil inlet cavity to the oil outlet cavity; and the outer arc line of the isolation plate is precisely and movably matched with the addendum circle of the inner gear to prevent engine oil in the tooth cavity of the inner gear from leaking out, the engine oil is conveyed from the oil inlet cavity to the oil outlet cavity, the rubber pad of the crescent plate guarantees the sealing effect in the pump body, and a buffering seats provides the overall stability.
Description
Technical field[0001]The present invention relates to a gear oil pump, which is specifically a gear pump for a stability.Background technique[0002]The oil pump of the existing engineering mechanical gearbox lubrication system uses a sputtering, drip feeding or a swing rotor pump, which is low, the lubrication efficiency is low, the sealing effect is poor, the vibration is large, the mechanical friction coefficient is high, resulting The abnormal wear of the part reduces the work efficiency of the gearbox.Inventive content[0003]1. To solve the problem[0004]For the problems present in the prior art, the object of the present invention is to provide a sealed adult oil pump that solves the problems mentioned in the above background stories.[0005]2. Technical solutions[0006]In order to achieve the above object, the present invention provides the following technical solutions:[0007]A stability gear pump, including pump body, pump cover, an internal gear, an outer gear, a drive shaft, a mi...
