Abstract
The utility model provides a novel integrated axial plunger pump which comprises a variable part and a main part. A pump shell and a pump body of the main part are cast into a whole; a channel is additionally arranged at the connecting position between a variable shell and a shell body, so as to lead an inner cavity of the variable shell to be communicated with an oil leakage port. The integrated axial plunger pump has the characteristics of reasonable design, simple structure, low energy consumption, low noise, long service life and high popularization value.
Description
Technical field:
The utility model relates to a kind of axial piston pump, is a kind of novel integrated axial piston pump specifically.
Background technique:
Present all CY14-1B axial piston pumps, the pump housing, pump case all separate, both link to each other by screw, easy leakage of oil and complex process during high pressure, consumes energy is big, and the oil of variable shell inner chamber is by the gap draining between the bearing roller, makes chamber pressure become big under the situation of high speed rotating, high pressure easily, produce entrap phenomenon, descended to the working life of pump itself.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, power consumption is low and the novel integrated axial piston pump of long service life.
Technical solution of the present utility model is:
The utility model comprises main body and variable part: the transmission shaft in the main body (1), cylinder body (6) is contained in the housing (30), oil distribution casing (5) is contained between cylinder body (6) and housing (30) interior edge face, locate by locating stud, the other end of housing (30) is equipped with single-row radial ball bearing (4) by transmission shaft (1), rubber oil seal with reinforce (3) and oil sealing base (2), with back-up ring it is blocked, be connected with spline between transmission shaft (1) and cylinder body (6), spring seat (13) is contained in transmission shaft (1) one stomidium, central spring (14) is contained in the spring seat (13) with interior cover (15), central spring (14) withstands on steel ball (16) in the ball-and-socket in backhaul dish (28) center portion through interior cover (15), plunger (9) bulb bag is locked in the piston shoes (10), whole slippery boots assembly is enclosed within the hole on the backhaul dish (28), variable head (25) in the variable part is contained in the variable shell (24), variable piston (18) is associated with variable head (25) by bearing pin (29), servopiston (19) is contained in variable piston (18) upper end hole, last top central spindle of the spring (20), interior outer spring (21) is contained on the central spindle of the spring, be associated with spring housing (23), thrust plate (12) is fixed on the variable head (25) by bearing pin, and piston shoes (10) are being pressed under the effect of central spring (14) on the thrust plate (12).
Novel integrated axial piston pump is cast as one with original pump case, the pump housing, now claims housing, has deducted screw that connects usefulness and the O RunddichtringO that seals usefulness, and has reduced the mach time, makes technology simple, has significantly reduced cost.
The utility model is rational in infrastructure, increase by place's passage in variable shell and housing joint, the variable shell inner chamber is connected with drain tap, making originally will be by the oil of the ability draining of the gap between the bearing ball, flow directly to drain tap by passage, the chamber pressure that has solved under high speed rotating, high-pressure situations is big, produces the phenomenon of pocketed oil, and improved the working life of pump greatly.
The utility model has with traditional comparing processes advantage simple, with low cost, long service life.
Description of drawings:
