Description
Technical field
This utility model relates to lubricating oil pump, is specifically related to the gear shaft of a kind of lubricating oil pump.
Background technology
It is provided with travelling gear in lubricating oil pump, for realizing high accuracy, low noise requirement, its transmission injection made gear, generally adopts
Complete with plastics integral molded plastic by shaft member.For the logical machine of realization, high-power, high torque requirements, uses prunus mume (sieb.) sieb.et zucc. between shaft member and plastic gear
Flower-shape inserts combines.The course of processing is: the inserts interference fit combination after shaft member and Precision Machining, after combination again with plastic gear
Integral molded plastic.Having the disadvantage that inserts technological process is long, production cost is high, heavier-weight.
Summary of the invention
The purpose of this utility model is to propose the gear shaft of a kind of lubricating oil pump, and this gear shaft uses plastic gear and power transmission shaft
Be molded into the structure of one, plastic gear and power transmission shaft stable connection, and injection step to be easily achieved, have working (machining) efficiency high and
The feature that processing cost is low.
The gear shaft of a kind of lubricating oil pump described in the utility model, including the power transmission shaft being coaxially disposed and plastic gear, institute
The periphery of the left part stating power transmission shaft is provided with plane, forms flat axle construction, described biography with the left part at described power transmission shaft
Two spiral grooves are distributed on the periphery of the right part of moving axis, and two described spiral grooves reversely intersect, every described spiral
Bent above to form overhead structure to this spiral grooves of one sidewall of groove, and described overhead structure is partly suspended from this
On spiral grooves；Described plastic gear is formed at the right part of described power transmission shaft, two described spiral grooves by Shooting Technique
It is correspondingly arranged with described plastic gear, and on described plastic gear, is formed with the spiral bar being filled in described spiral grooves, with
Increase the adhesive force of described plastic gear and described power transmission shaft.
Further, the right side of described plastic gear is positioned at the left side of described power transmission shaft right side.
Further, described overhead structure height 0.5mm-0.8mm, angle of inclination is 40 °-55 °.
In this utility model, plastic gear is formed on power transmission shaft by Shooting Technique, and is provided with on power transmission shaft and moulds
The material spiral grooves answered of gear mesh and overhead structure, be provided with spiral grooves and make plastic gear the most firm with the combination of power transmission shaft,
Arranging overhead structure, to further reduce the processing of the probability that plastic gear comes off, spiral grooves and overhead structure the simplest
Single, utilize spiral grooves and overhead structure to fix plastic gear, it is easy to accomplish, alleviate the weight of gear shaft, and have
The feature that working (machining) efficiency is high and processing cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of power transmission shaft；
Fig. 3 is the cooperation schematic diagram of plastic gear and power transmission shaft.
In figure: 1 power transmission shaft；2 plastic gears；3 planes；4 spiral grooves；5 overhead structures.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
The gear shaft of a kind of lubricating oil pump as shown in Figure 1-Figure 3, including the power transmission shaft 1 being coaxially disposed and plastic gear 2, passes
The periphery of the left part of moving axis 1 is provided with plane 3, forms flat axle construction with the left part at power transmission shaft 1, flat axle construction so that
In being connected with drive disk assembly, transmit moment of torsion.Two spiral grooves 4, two bar spirals are distributed on the periphery of the right part of power transmission shaft 1
Groove 4 reversely intersects, bent above to form overhead structure 5 to this spiral grooves 4 of a sidewall of every spiral grooves 4,
And overhead structure 5 is partly suspended from this spiral grooves 4；Plastic gear 2 is formed at the right side of power transmission shaft 1 by Shooting Technique
Portion, two spiral grooves 4 are correspondingly arranged with plastic gear 2, and are formed with the spiral shell being filled in spiral grooves 4 on plastic gear 2
Rotation bar, to increase the adhesive force of plastic gear 2 and power transmission shaft 1.
Further, the right side of plastic gear 2 is positioned at the left side of power transmission shaft 1 right side so that the right-hand member of power transmission shaft 1 to
Right protrusion, convenient installation gear shaft.
Preferred as one, the high 0.5mm-0.8mm of overhead structure 5, angle of inclination is 40 °-55 °.
