Description
Technical field
The present invention relates to speed reducer founding materials production technical fields, and the worm and gear specially with output axle construction slows down
Machine founding materials and preparation method.
Background technique
Worm-gear speed reducer is a kind of power transmission mechanism, using the velocity transducer of gear, by the winding number of motor
Desired winding number is decelerated to, and obtains the mechanism of larger torque, in the mechanism for transmitting power and movement, speed reducer
Application range is quite extensive, its trace, ship, vapour from the vehicles can be seen in the transmission system of various machinery
Vehicle, locomotive, heavy machinery for building, machining machine and tool and automated production equipment used in mechanical industry, into daily life
Common household electrical appliances, clock and watch etc., application arrive Smaller load from the transmission work of big power, and accurate angle transmission can be shown in
To the application of speed reducer, and in industrial application, speed reducer, which has, to slow down and increases torque functions, therefore is widely used in speed
With the conversion equipment of torque, three mostly important components are worm gear, worm screw and output shaft in worm-gear speed reducer, in worm gear
In the worm decelerating machine course of work, long term wear is mutually driven between worm gear and worm screw, it is therefore desirable to the material of worm and gear
It optimizes, while output shaft will receive extraneous impact force or torque in the long-term use, therefore be also required to output
The material of axis optimizes, to ensure that worm-gear speed reducer is able to carry out long-term use.
The worm gear of worm-gear speed reducer, worm screw and output shaft directly adopt single alloy steel material mostly and are cast at present
Processing is made, however, such material has the following deficiencies:
1), the worm gear of single alloy steel and worm screw in the long-term use, are easy to happen abrasion between the gear teeth and bar tooth,
When wearing to a certain extent, that is, it will appear skidding, to seriously affect the normal engaged transmission between worm gear and worm screw.
2), the impulse fatigue resistance of the worm gear of single alloy steel and worm screw can be poor, and toughness is lower, long-term to engage
It squeezes, the gear teeth and bar tooth can be made to deform, thus the case where also resulting in skidding generation.
3), the impact resistance of the output shaft of single alloy steel is poor, in long-term use process or multiple unexpected punching
It hits, output shaft is easily broken off, to prevent worm-gear speed reducer from normal use.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides the worm-gear speed reducer founding materials with output axle construction and preparations

It is easy to happen abrasion between bar tooth, when wearing to a certain extent, that is, will appear skidding, to seriously affect worm gear and worm screw
Between positive production engaged transmission, the impulse fatigue resistance of the worm gear of single alloy steel and worm screw can be poor, and toughness is lower,
Long-term engagement squeezes, and the gear teeth and bar tooth can be made to deform, thus the case where also resulting in skidding generation, and single alloy steel products
The impact resistance of the output shaft of matter is poor, and in long-term use process or multiple accidental shock, output shaft is easily broken off, thus
Prevent the problem of worm-gear speed reducer is from normal use.

Test experiments
Certain machinery production enterprise uses the preparation method of 1-3 of the embodiment of the present invention, prepares three groups of worm-gear speed reducers respectively and produces
Product, while the WPA worm-gear speed reducer for choosing same type in the market is as a control group, then subtracts respectively to every group of worm and gear
Worm gear, worm screw and the output shaft of fast machine carry out four Secondary Shocks experiments, record worm gear, the worm screw of every group of worm-gear speed reducer respectively
Each maximum anti-shock loading, every later group of worm-gear speed reducer are separately connected the electricity of identical output power with output shaft
Then motivation and output loading carry out trial operation test experiments, every group of worm-gear speed reducer are observed during experiment
Vibration and noise situation, record first appears the time of vibration, after four groups of worm-gear speed reducers do not shut down trial operation 72-96h,
Every group of worm-gear speed reducer is disassembled, the abrasion condition of worm gear and worm screw inside every group of worm-gear speed reducer is observed,
And it records.
The shock resistance experimental result statistical form of 1 embodiment 1 of table
The shock resistance experimental result statistical form of 2 embodiment 2 of table
The shock resistance experimental result statistical form of 3 embodiment 3 of table
The shock resistance experimental result statistical form of the existing worm-gear speed reducer of table 4
By above-mentioned table 1-4 it is found that the worm gear of worm-gear speed reducer prepared by embodiment 1, worm screw and output shaft are born
Maximum impact is maximum, and the worm gear of worm-gear speed reducer prepared by embodiment 2 and embodiment 3, worm screw and output shaft are held
The maximum impact received is bigger than choosing the WPA worm-gear speed reducer of same type in the market.
5 72-96h vibration noise of table and worm and gear abrasion condition statistical form
As shown in Table 5, embodiment 1-3 does not occur the case where vibration noise when carrying out 72-96h trial operation test experiments, and
The WPA worm-gear speed reducer for choosing same type in the market occurs the case where vibration noise, while embodiment 1-3 in 73.8h
After carrying out 72-96h trial operation test experiments, worm gear is glossy with worm screw face, without any abrasion, and chooses same type in the market
The worm gear of WPA worm-gear speed reducer and the surface of worm screw have polishing scratch.
In summary
The present invention can avoid worm gear by one layer of SMA carbon fiber film of surface adhesion in worm gear cast member and worm screw cast member
With the direct contact wear of worm screw face, simultaneously because SMA carbon fiber film have excellent wear-resisting property, can substantially increase worm gear and
Mesh degree between worm screw avoids the occurrence of the case where worm and gear skids, simultaneously because SMA carbon fiber film surface well
There is certain fibre gap, lubricating oil can be detained well, so that the degree of wear between worm and gear is substantially reduced, thus
It ensure that the normal engaged transmission between worm gear and worm screw well, by adding in worm gear founding materials and worm screw founding materials
Enter Ultimum Ti, makes the worm gear of preparation and worm material that there is stronger toughness, avoid worm gear well and worm screw is long
Phase engagement squeezes, and the gear teeth and bar tooth is made to deform, thus the case where also resulting in skidding generation, while by worm material
Manganese-titanium, chrome-silicon powder, rhenium powder and nano silica are added in component, the shock resistance of Lai Tigao worm screw material is led to
It crosses and rear earth zinc-aluminium alloy, copper oxide, glass putty, titanium dioxide powder and graphite is added in worm gear material component, it can be achieved that improving snail
The shock resistance of pole stock matter substantially prolongs to greatly strengthen the impulse fatigue resistance energy and toughness of worm gear and worm screw
The service life of worm and gear, while being closed by the way that tungsten carbide, manganeisen, chromium powder, chrome molybdenum are added in output shaft founding materials
Gold, quartz sand, bauxite, nickel powder and cadmium powder, can greatly promote the impact resistance of output shaft, avoid output shaft in length well
The case where phase uses or repeatedly during accidental shock, and output shaft is easily broken off, to ensure that worm-gear speed reducer
Normal use.
