Abstract
The utility model relates to an diesel engine water pump, which comprises a pump body and a water pump shaft, the water pump shaft in the pump body is equipped with a cylindrical roller bearing and a deep groove ball bearing, two jackscrews are symmetrically disposed on the pump body at the outer ring of the deep groove ball bearing, because the jackscrews replace elastic collar for holes, the jackscrews can firmly press the deep groove ball bearing, and then the deep groove ball bearing can not move axially, thereby realizing the accurate location of the deep groove ball bearing, and prolonging the service life of products.
Description
Technical field
The utility model relates to a kind of water pump, specifically, relates to a kind of diesel pump.
Background technique
In traditional diesel pump, rotating shaft in the pump housing is provided with two bearings, one is deep groove ball bearing, another is a roller bearing, usually adopt circlip for hole that it is positioned, owing to have the slit between deep groove ball bearing and the circlip for hole, move along the axial direction of water pump spindle the outer ring that causes deep groove ball bearing, can not accurately locate deep groove ball bearing, influence the working life of product.
The model utility content
The purpose of this utility model provides a kind of diesel pump of a kind of accurate positioning, long product lifecycle.
For achieving the above object, the technological scheme that the utility model adopted is: a kind of diesel pump, comprise the pump housing and water pump spindle, water pump spindle in the described pump housing is provided with roller bearing and deep groove ball bearing, it is characterized in that: be symmetrically arranged with two jackscrews on the pump housing at place, described deep groove ball bearing outer ring.
Beneficial effect: the utility model is taked above technological scheme, have the following advantages: owing to replaced circlip for hole with jackscrew, jackscrew can be pushed down deep groove ball bearing tightly, deep groove ball bearing can not move axially, realized accurate location, the working life of having improved product to deep groove ball bearing.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model middle pump body.
Embodiment
