Abstract
The utility model provides a kind of gear pump front support drive assembly.This gear pump front support drive assembly is independent external transmission mechanism, can be arbitrarily be used cooperatively with gear pump；Internal messing spline drived is selected in the connection place of itself and gear pump, makes transmission more steady；Its front end axis, which is stretched, stretches that size is identical, and such user can increase front support structure on the premise of gear pump installation end connection mode is not changed with the axis of gear pump；The spring bearing of large bearing capacity is internally provided with, radial direction input load can be born, stretches and is deformed by radial load so as to avoid the axis of gear pump, ensure the efficiency and service life of gear pump；Its rear end output ensures concentricity using conical surface blind-mate.With gear pump seam allowance using small―gap suture cooperation, positioning of floating, transmission is avoided to interfere；Its input/output terminal is designed with dust-proof sealing structure, ensures mechanism service life.
Description
Technical field
The utility model is related to a kind of gear pump front support drive assemblies.
Background technology
Gear pump is by the phase of a pair of of parameter involute gear identical with structure in the case where axis stretches the driving of input torque
Engagement is mutually rolled, converts mechanical energy into the important component of hydraulic energy.Some special hydraulic systems, due to the limit of various factors
System causes the type of drive of its gear pump that can only select radially to input.And common gear pump is when inputting driving torque, axis
Extending portion point, which bears radial load, can seriously affect the performance and used life of pump.So, the radial direction that should meet user is defeated
Enter mode, ensure performance and the service life of pump again, then the design of gear pump front support transmission mechanism just seems particularly heavy
It will.
The content of the invention
The utility model provides a kind of gear pump front support drive assembly, and the assembly can not only ensure that gear pump exists
Comprehensive performance and service life when being run under higher operating mode, moreover it is possible to meet the special mounting form of radially input, greatly improve
The scope of application of gear pump.
What the utility model was formed by, it includes housing, transmission shaft, spring bearing, drive splines set, location sealing
Stent, sealing ring, baffle ring, key, washer, oil sealing and nut.
Coordinate in housing equipped with spring bearing, bearing with transmission shaft transition, transmission shaft is with drive splines set using in spline
Engaged transmission, equipped with baffle ring, key, washer, nut on transmission shaft, housing forward end is equipped with oil sealing, and housing rear end is equipped with location sealing
Stent is equipped with sealing ring on sealed support.
As a result of above-mentioned technology, enable gear pump bear radial load when installing and inputting and from driving form
Limitation, make its transmission more steady reliable, make hydraulic system structure compacter, improve the scope of application of gear pump.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 be in Fig. 1 A-A to schematic cross-sectional view.
Specific embodiment
In the spring bearing 8 for being internally provided with large bearing capacity of housing 6 radial load is born with the interference fit of housing 6；Transmission shaft 4
Coordinate with 8 transition of bearing and transfer torque, its one end ensures concentricity and transmission intensity for conical surface blind-mate, and the other end is interior
Spline drived compensates offset；3, two nut 1, washer 2, woodruff key baffle rings 7 are formed on transmission shaft 4 with bearing 8 and are driven
Axle assembly, then in whole press-in housing 6；6 one end of housing is equipped with outside framework oil seal 5, and the other end is equipped with location sealing stent 10；It is fixed
Position sealed support 10 is equipped with interior external seal O-ring seals 11,12；Location sealing stent 10 is coordinated with housing 6 using small―gap suture
Transmission offset can be compensated again, and transmission can effectively be avoided to interfere；Drive splines is covered between 9 external splines and transmission shaft internal spline
Gap coordinates, and inside is driven for the conical surface, and conical surface parameter is identical with the transmission shaft front end conical surface, and interior key can have with woodruff key 3
Effect cooperation.
