Abstract
The invention discloses a process for effectively reducing noise of a gear in a main shaft box of a machine tool. The process relates to a transmission gear of the main shaft box and damping materials which coat grooves, wherein the grooves are formed in the two end faces of the transmission gear. Therefore, the noise of the machine tool is reduced. According to the scheme, the noise of the machine tool is reduced, cost is low, effectiveness is quickly achieved, operability is high, the noise of the machine tool can be remarkably reduced, so that the process can meet and is superior to the national standard requirements.
Description
Technical field
The present invention relates to a kind of process using of machine tool component structure, especially the technology of headstock internal gear noise reduction.
Background technique
The machine noise of mechanical speed change mainly comes from the gear of headstock.The headstock internal gear is big because of rotating speed height, load, so noise is also big.Require the machine noise must not be greater than 83dBA as NBS, but it is more and more higher to be accompanied by the precision of lathe, it also be more and more higher that the client requires the noise of lathe.Sometimes the lathe client in the NBS scope can complain noise big, and this has just proposed the problem of a sound insulation and noise reduction.Traditional noise reduction mode improves the grade of accuracy of gear for improving the precision in headstock hole.But these two kinds of methods play a role clearly under the lower situation of ratio of precision (when being lower than 7 grades as accuracy of gear grade), but improving requirement when grade of accuracy reaches certain degree again has been not clearly just to the effect of noise, and cost is doubled and redoubled, thereby makes product lose competitive ability.
Summary of the invention
The invention provides a kind of technology for reducing lathe headstock internal gear noise.This process implementing way is simple, with low cost, can significantly reduce the noise that is caused by gear, and significantly changes its melodious property.
The technical solution used in the present invention is: the gearwheel both ends of the surface of headstock transmission are processed groove, and in groove the spraying certain thickness noise sorbing material (as plastic-blasting), reduce and block bump vibrations and noise that gear produces in the process of engagement driving, the sound that makes gear send at the transmission initial stage namely is suppressed, thereby reduces the noise of whole lathe.
The employed material of lathe all is metallic material more than 99%, comprises case.The damping capacity of metallic material is low-down, can't intercept propagation and the vibrations of sound effectively, so be necessary very much to increase the noise sorbing material, it also is best increasing its damping effect of noise sorbing material at the vibration source place of sound simultaneously, and the cost of increase is minimum.
More do not apply the low 4-6dBA of machine noise of damping material through the lathe of the damping material of gear coating under the same conditions after the actual tests.
Description of drawings
Fig. 1 is the present invention program's schematic representation.
Embodiment
Process groove as shown in the figure in the gear both sides, to alleviate the rotary inertia of gear.
Groove is cleaned up, to strengthen the adhesion of damping material.With special tooling wheel tooth portion is protected, be sprayed onto tooth portion to prevent damping material, influence the accuracy of mesh.
Be coated on damping material in the groove and dried, thickness is good with 0.5mm.(can apply special-purpose damping material, also can plastic-blasting).
Claims (4)
1. a technology that effectively reduces lathe headstock internal gear noise is applied to the noise reduction of machine tool chief axis gear graduation, comprises Gear Processing is gone out groove, and apply damping material within groove.
2. it is characterized in that: the driving gear both ends of the surface are processed into groove, and in groove, apply damping material, thereby the noise that sends when making gear operation reduces.
3. the technology of effective reduction lathe headstock gear noiose according to claim 2 is characterized in that: the driving gear both sides that are used for lathe headstock are processed to groove.
4. the technology of effective reduction lathe headstock gear noiose according to claim 2 is characterized in that: apply the thick damping material in the 0.5mm left and right sides in the headstock in the driving gear grooves on two sides.
