Abstract
The utility model relates to a novel gear oil pump driving device which utilizes a transmission shaft structure, wherein an electric motor (1) is connected with a gear oil pump (2) through a transmission shaft (3).A hub (4) of the electric motor (1) is fixedly connected with an electric motor connecting end (5) of the transmission shaft (3) by screw threads; the other end of the transmission shaft (3) is a circular sleeve (6); a card slot is arranged on the inner wall of the sleeve (6); a card corresponding to the card slot is arranged on a connecting shaft (7) of the gear oil pump (2); and the connecting shaft (7) is connected with the sleeve(6) in an inserting way. The novel gear oil pump driving device ensures that the relative position of the connected two shafts can transmit power reliably when changing within the expected scope, and has the advantages of high transmission efficiency, long service life, simple structure, and is convenient to produce and easy to maintain.
Description
Technical field
The utility model relates to various mechanical Hydraulic Field, particularly relates to a kind of novel gear oil pump drive unit.
Background technique
Tradition engineering machinery vehicle gear oil pump driving mode major part is selected vee belt transmission or coupling transmission dual mode for use.But because the engineering machinery working strength is big, the vee belt of adopting just is easy to become flexible, and causes oil pump to be short of power, and then supply hydraulic oil that can't be timely or sufficient, causes equipment work efficient and quality to descend.Though transmitting torque is big in theory for gear coupling commonly used, must the durable work of ability under the condition of lubricated and good seal.And need the running check sealing condition, annotate lubricant oil or lubricating grease, maintenance workload is big, has increased unproductive time, has reduced the effective time, influences productivity effect.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art exactly, thereby a kind of novel gear oil pump drive unit is provided, and this device can carry out power reliably and transmit long service life.
For realizing above-mentioned purpose; The utility model is to adopt following technological scheme to realize: a kind of novel gear oil pump drive unit; It is characterized in that: drive unit adopts transmission shaft structure; Be to be connected through transmission shaft (3) with gear oil pump (2) by motor (1), the wheel hub (4) of motor (1) and the motor connecting end (5) of transmission shaft (3) are fixing through being threaded; The other end of transmission shaft (3) is circular casing (6), on sleeve pipe (6) inwall draw-in groove is arranged, and the coupling shaft (7) of gear oil pump (2) is provided with the card corresponding with draw-in groove, and coupling shaft (7) inserts sleeve pipe (6) and connects.
The utility model characteristics: 1, guaranteed connect diaxon relative position when in the expectation scope, changing, transferring power reliably;
2, the additional load that produces owing to true joint angle, vibration and noise are in allowed band; So guaranteed connect diaxon and can evenly turn round.
3, transmission efficiency is high, and long service life is simple in structure, easily manufactured, and maintenance easily.
