Abstract
The present invention relates to a kind of Hardened gear face double helical spurgear speed reducers, simplify processing technology, improve the assembly precision and speed of speed reducer, belong to technical field of mechanical processing.Double helical spurgear speed reducer greatly can not roll flute due to Gear Processing difficulty, the soft flank of tooth can only be done, double helical spurgear is assembled by left-handed gear and the positioning of dextrorotation gear with helical gear, since the factor of the accumulated errors such as processing and centering, positioning, compensation rate adjustment can only also be made into the soft flank of tooth, regarding to the issue above, the present invention provides a kind of Hardened gear face double helical spurgear speed reducer, does not have error can be with roll flute between the left-hand teeth and right-hand teeth of double helical spurgear, gear is up to highest level.
Description
Technical field
The present invention relates to a kind of Hardened gear face double helical spurgear speed reducers, simplify processing technology, improve the dress of speed reducer
Service life is extended with precision, belongs to technical field of mechanical processing.
Background technique
In recent years, with the continuous progress of science and technology, double helical spurgear transmission is used widely, especially in nuclear power, stone
The some special industries application such as oil probing more but be all the soft flank of tooth.The bearing capacity of gear teeth face has with tooth face hardness
It closes, hardness is higher, then its bearing capacity is also higher.According to the size of tooth face hardness, gear drive is divided into two classes by usual people,
That is hardened face gear transmission and soft tooth flank gear transmission.The tooth face hardness of usual a pair of engaged gears is all larger than 350HBS, referred to as
Otherwise hardened face gear is known as soft tooth flank gear.Double helical spurgear speed reducer is since Gear Processing difficulty is big and does not do
Method roll flute can only make soft flank of tooth double helical spurgear speed reducer, adult by left-handed gear and the positioning assembling of dextrorotation gear with helical gear
Font gear can effectively reduce difficulty of processing, but due to processing and the accumulated errors such as centering, positioning, compensation rate adjustment
Factor can only also be made into the soft flank of tooth because the ratcheting deviation of soft tooth flank gear can by merge gnaw tooth method it is ground.
And same deviation Hardened gear face cannot gnaw tooth, destroy tooth once gnawing, so the double helical spurgear speed reducer of Hardened gear face is domestic
It cannot produce, can foreign countries do not know produce yet.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of Hardened gear face double helical spurgear speed reducer, including speed reducer lower case, it is main
Moving axis, the left-handed pinion gear of active, active dextrorotation pinion gear, drive shaft bearing, drive shaft bearing shelves lid, drive shaft bearing oil sealing,
Driven axle, passive left-handed gear wheel, passive dextrorotation gear wheel, expansion sleeve, driven shaft bearing, driven shaft bearing shelves lid, driven axle
Bearing enclosure, speed reducer lower case, fastening bolt, positioning pin.
Core of the invention is that one in the left or right rotation gear of every level-one reduction gearing is arrived with expansion sleeve swelling
On axis, gear does not have to centering and positions and detect, and all errors are eliminated by that gear with expansion sleeve, and no matter what slows down,
It is all protection category of the invention with several expansion sleeves.
Describe the present invention by taking primary speed-down as an example below to solve the above problems used technical solution: gear uses
Hardened face gear, driving gear shaft is loaded in the position of left-hand teeth and right-hand teeth and once mills out two keyways, a pair through overheating
Processing, roll flute, milled with mold centering the oblique wheel of keyway by left-hand teeth, right-hand teeth direction plus key hot jacket to axis on, load onto axis
It is attached on reducer shell after holding, driven axle left-hand teeth position is milled out keyway, left-handed passive gear wheel plus key hot jacket to quilt
On moving axis, the inner hole that expansion sleeve penetrates the passive gear wheel of dextrorotation is refilled driven axle right-hand teeth position later, loads onto bearing peace
It is attached on reducer shell, adjusts expansion sleeve swelling of the gear clearance dextrorotation gear wheel.Multi-stage speed-reducing, every level-one is with one
Expansion sleeve, which installs, just can be used, and not have to adjustment.
The beneficial effects of the present invention are: 1. due in every level-one with an expansion sleeve so that processing technology becomes most simple
It is single, it reduces assembly difficulty and improves assembly precision and speed.2. double helical spurgear speed reducer becomes hard tooth from the soft flank of tooth
Behind face, thickness, modulus, the diameter of gear have all become smaller and can reduce cost, and gear mesh face reduces, and resistance to sliding becomes smaller, can
With energy saving.
