Abstract
A gear pump includes a pair of gears having meshed teeth. One of the gears is configured for connection to a source of drive. The gears are received within a housing. The housing has an inlet port configured for connection to a source of fluid and an outlet port. Each of the gears have a shaft rotating within the housing on a bearing on each axial side of each gear. At least one of the bearings associated with each of the pair of gears has a plurality of springs received in recesses to bias the said at least one bearing against an end face of a respective one of the pair of gears. A retention plate holds each of the plurality springs. A method of assembly is also disclosed.
Claims20
A gear pump comprising:
- a pair of gears having meshed teeth, one of said gears configured for connection to a source of drive;
- said gears received within a housing, the housing having an inlet port configured for connection to a source of fluid and an outlet port;
- each of said gears rotating within a bearing on each axial side of each said gear;
- at least one bearing associated with each of said pair of gears having a plurality of springs received in recesses to bias said at least one bearing against an end face of a respective one of said gears;
- and
- a spring retention plate attached to each of said plurality of springs.
A method of assembly comprising the steps of:
- mounting a plurality of coil springs to a spring retention plate, and then moving the spring retention plate with the plurality of coil springs into a plurality of recesses in an associated component.
A gear pump comprising:
- a pair of gears;
- and
- a bearing mounted at each of two axial ends of each said gear, and there being bias means biasing at least one of said bearings against an end face of at least one said gears, the bias means including an assembly and retention mean, which secures the bias means within the at least one said bearing, such that said assembly and retention means and said bias means can be inserted as an assembled unit into said at least one bearing.
