Abstract
The invention discloses a gear pump with a fan. The gear pump comprises a driving shaft, a driven shaft and a pump shell, wherein a front end cover and a rear end cover are arranged on two sides of the pump shell respectively; one end of the driving shaft extends out of the front end cover and is connected with an external power shaft, and the other end of the driving shaft extends out of the rear end cover and is connected with the fan; the other side, matched with the pump shell, of the rear end cover is further provided with a fan housing. The driving shaft is sleeved with a driving gear, the driven shaft is sleeved with a driven gear, and the driving gear and the driven gear are linearly engaged. According to the scheme, the gear pump has the beneficial effects that a large amount of heat is generated during work of the driving gear and the driven gear and transmitted to the rear end cover, heat on the rear end cover is taken away by the fan, and therefore the heat generated during work of the gear pump is dissipated in time, it is guaranteed that the gear pump works at proper temperature all the time, and the service life of the gear pump is prolonged.
Description
Technical field
The present invention relates to gear pump, be specially a kind of gear pump with fan.
Background technique
Gear pump is a kind of conventional oil hydraulic pump, and its major advantage is that structure is simple, easily manufactured, cheap, volume is little, lightweight, self-priming performance is good, insensitive to oil contamination, reliable operation, but gear pump is in running, and its inside easily produces high temperature, because gear pump mainly relies on pump housing surface to carry out heat loss through radiation, and pump housing surface radiating is limited in one's ability, timely the high temperature of gear pump inside can not be shed, thus reduce the working life of gear pump.
Summary of the invention
The invention is intended to provide a kind of can in time the high temperature of gear pump inside be distributed, improve the gear pump of the band fan in working life.
The gear pump of the band fan in this programme, comprise driving shaft, driven shaft and pump case, pump case both sides are respectively equipped with front cover and rear end cover, driving shaft one end is stretched out front cover and is connected with external impetus axle, the driving shaft the other end stretches out rear end cover and is connected with fan, and the opposite side that rear end cover coordinates with pump case is also provided with fan housing, and on driving shaft, cover has driving gear, on driven shaft, cover has driven gear, and driving gear linearly engages with driven gear.
The working principle of this programme is: in gear pump working procedure, external impetus axle drives driving shaft running, the fan be arranged on driving shaft will operate simultaneously, meanwhile drive also operates with its driven gear linearly engaged by driving gear, the tooth of driving gear and driven gear is constantly engaging-in, engagement, nibble out, throw off, engage again, and then reach the object of suction liquid, a large amount of heats will be produced in the working procedure of driving gear and driven gear, this heat is delivered to rear end cover, heat on rear end cover will be taken away through fan, thus the heat produced in gear pump working procedure can be distributed in time, ensure that gear pump always works in suitable temperature, improve the working life of gear pump.
Further, driving shaft and front cover cooperation place are also provided with and generate heat the wavy spring in gap for compensating driving shaft, the phenomenon of elongation can be produced because driving shaft is heated in the course of the work, driving shaft compressible wavy spring in elongation process realizes the auto-compensation in heating gap, thus avoids the stuck of driving shaft.
Further, in order to reduce its weight as far as possible on the basis ensureing front cover and rear end cover intensity, front cover offering the first groove for weight reduction, rear end cover offering the second groove for weight reduction.
Further, described driving shaft is connected with described driving gear flat key, and described driven shaft is connected with described driven gear flat key, flat key connect reliable performance and convenient disassembly.
