Description
Technical field
The present invention relates to a kind of oil hydraulic pump.
Background technique
Current oil hydraulic pump, assemble driving gear on its engine output shaft, and directly stretch in fuel tank, so the temperature that engine body work is produced is directly conducted in fuel tank, make the interior hydraulic oil temperature rise of fuel tank very fast, cause hydraulic oil viscosity to descend, separately because of driving gear, in fuel tank, with per minute 3000, turn above speed rotation, produce a large amount of steam bubbles, it has destroyed the service behaviour of hydraulic oil, affect pressure value, also have in addition existing hydraulic pump system structural design too compact, mounting or dismounting and maintenance are very inconvenient.
Summary of the invention
The invention provides a kind of engine-driven hydraulic pump, purpose is that the driving mechanism that solves existing oil hydraulic pump makes hydraulic oil temperature raise, and viscosity descends; Built-in driving gear makes hydraulic oil produce the problem of steam bubble; And it is too compact to overcome existing design of hydraulic pump, the defect of mounting or dismounting and inconvenient maintenance.
The present invention includes fuel tank, motor, plunger pump, described plunger pump is arranged on the inboard of described fuel tank sidewall, the shaft extension end of the line shaft of described plunger pump is arranged on outside described fuel tank through the fuel tank sidewall, be fixedly connected with driven gear on plunger pump line shaft outside fuel tank, be bolted to connection the split chamber cap on described fuel tank outer side wall, described driven gear is arranged in described split chamber cap; Described motor is arranged on outside described fuel tank, the output terminal of described engine spindle is fixedly connected with the first half-coupling, at the output terminal of described the first half-coupling second half-coupling that is connected, between described first, second half-coupling, the vibration damping thermal insulating pad is set, output terminal at described the second half-coupling connects main output shaft, be fixedly connected with driving gear on described main output shaft, described main output shaft, driving gear are arranged in described split chamber cap, described driving gear and the engagement of described driven gear.
The present invention arranges a split chamber cap outside fuel tank, and driving and driven gear is set in the split chamber cap, becomes an independently drive mechanism chamber the fuel tank layman like this, the gear of high speed rotating can not exert an influence to hydraulic oil like this, can not produce steam bubble in hydraulic oil, its force value is also stable; In addition, between two half-couplings that connect at the motor output terminal, the vibration damping thermal insulating pad is set, has played the transmission of blocking-up motor to the gear temperature, it has avoided the impact of motor on the pressure oil temperature; Two half-couplings belong to two large parts, and the distance that it has increased between parts relatively, facilitated dismounting, and the split chamber cap is also more quick detachable, and the transmission part in it is more easy to assemble, maintenance also; By above-mentioned improvement, greatly reduce the rate of fault of product, protected hydraulic oil and other part, extended working life greatly, energy-saving and cost-reducing also more obvious.
Between the line shaft of plunger pump of the present invention and described fuel tank sidewall, spring bearing is set; Bearing can reduce friction, guarantees the stable operation of parts.
Between the line shaft of plunger pump of the present invention and described split chamber cap, spring bearing is set; Bearing can reduce friction, guarantees the stable operation of parts.
Between main output shaft of the present invention and described fuel tank sidewall, spring bearing is set; Bearing can reduce friction, guarantees the stable operation of parts.
The front portion of the second half-coupling of the present invention is arranged in described split chamber cap through the sidewall of split chamber cap, between described the second half-coupling and described split chamber cap, spring bearing is set; Bearing can reduce friction, guarantees the stable operation of parts.
On the present invention's split chamber cap corresponding on the top of the line shaft of described and plunger pump, through hole is set, the spring bearing of described plunger pump line shaft shaft extension end is arranged in described through hole, in described through hole outer end, is bolted to connection end cap; Through hole and detachable end are set, equally for convenient assembling and disassembling, maintenance.
