Abstract
The utility model discloses a kind of quasi-hyperbola driven wheel of differential for fork truck speed reducer assembly, including gear mass, gear mass center is provided with installing hole, and the gear mass of installing hole lower edge is provided with multiple screwed hole along annular space；Gear mass upper surface is taper surface, and taper surface is provided with the quasi-hyperbola cone tooth of multiple right-spiral spaced apart.This utility model is rational in infrastructure, and the tooth of gear mass is that the quasi-hyperbola of right-spiral bores tooth, significantly reduces gear engagement noise, is effectively increased gear fatigue resistance and anti-shear performance, and transmission torque is big；Multiple screwed holes that driven tooth wheel body is respectively provided with around the surrounding of installing hole, it is simple to the differential casing assembling matched, easy to maintenance.
Description
Technical field:
This utility model relates to fork truck decelerator processing technique field, particularly relates to a kind of for fork truck speed reducer assembly
Quasi-hyperbola driven wheel of differential.
Background technology:
Existing 5-7T ton forklift speed reducer assembly gear uses rivet interlacement with difference shell, and assembling is inconvenient, maintenance difficult,
And add cost；This external gear fatigue resistance and anti-shear performance are poor, and transmission torque is the most relatively small.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of standard for fork truck speed reducer assembly
Hyperbola driven wheel of differential, significantly reduces gear engagement noise, is effectively increased gear fatigue resistance and shear resistant
Can, transmission torque is big；The differential casing assembling being easy to and match, easy to maintenance.
The technical solution of the utility model is as follows:
Quasi-hyperbola driven wheel of differential for fork truck speed reducer assembly, it is characterised in that: include gear mass, in gear mass
The heart is provided with installing hole, and the gear mass of installing hole lower edge is provided with multiple screwed hole along annular space；Described gear mass
Upper surface is taper surface, and taper surface is provided with the quasi-hyperbola cone tooth of multiple right-spiral spaced apart.
The described quasi-hyperbola driven wheel of differential for fork truck speed reducer assembly, it is characterised in that described right-spiral
Quasi-hyperbola cone tooth the number of teeth be 39.
The described quasi-hyperbola driven wheel of differential for fork truck speed reducer assembly, it is characterised in that described installing hole
For shoulder hole, installing hole is made up of the circular port of epimere bellmouth and hypomere, described screwed hole and the upper end toper of installing hole
The mutual UNICOM in hole.
The utility model has the advantages that:
This utility model is rational in infrastructure, and the tooth of gear mass is that the quasi-hyperbola of right-spiral bores tooth, significantly reduces gear and nibbles
Closing noise, be effectively increased gear fatigue resistance and anti-shear performance, transmission torque is big；Driven tooth wheel body is around installing hole
Multiple screwed holes that surrounding is respectively provided with, it is simple to assemble with the differential casing matched, easy to maintenance.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
For the quasi-hyperbola driven wheel of differential of fork truck speed reducer assembly, including gear mass 1, gear mass 1 center is provided with peace
Dress hole 2, the gear mass of installing hole 2 lower edge is provided with multiple screwed hole 3 along annular space；Gear mass 1 upper surface is cone
Shape face, taper surface is provided with the quasi-hyperbola cone tooth 4 of multiple right-spiral spaced apart, significantly reduces gear engagement and make an uproar
Sound, is effectively increased gear fatigue resistance and anti-shear performance, and transmission torque is big.
The number of teeth of the quasi-hyperbola cone tooth 4 of right-spiral is 39.
Installing hole 2 is shoulder hole, and installing hole 2 is made up of the circular port 2-2 of epimere bellmouth 2-1 and hypomere, screwed hole with
The mutual UNICOM of upper end bellmouth of installing hole, it is simple to assembled by bolt with the differential casing matched, be greatly simplified
Operative employee assembling, maintenance labor intensity, saved cost.
