Abstract
The invention relates to a kind of bevel gear of high-speed industrial sewing machine, which is composed of steel parts and bevel gear. Bevel gear is constituted of wear resistant materials including molybdic sulfide, Teflon, glass fiber or carbon fiber, one or combination of polyformaldehyde, nylon 66 or PEEK. Steel parts present as cylindrical tubes, which are connected with bevel gear by thermoplastic structure or thermosetting structure. The invention has intensity, rigidity and greasy property. It can stick its own materials to surface of adjacent gear and stuff minute roughs in contact surfaces. Therefore, coefficient of friction approaches zero, which realizes its using in drive gear of upper and bottom spindle of high-speed industrial sewing machine without grease oil. The invention has low productive cost, small shock, low noise, small wear and long using lifespan.
Description
Technical field
The present invention relates to mechanical transmission component, relate in particular to the axle of transferring rotational motion, more particularly, the present invention is a kind of bevel gear that is used for high-speed industrial sewing machine.
Background technology
Last axle rotating speed is higher than 1000 rev/mins industrial sewing machine and adopts transmission of power that gear structure will go up axle to lower shaft, and gear transmission has the advantages that speed is fast, efficient is high, vibrations are little and noise is low.But further raising along with last axle speed, the frequent motion of the contact friction repeatedly of each tooth of steel gear makes that temperature begins to rise, the surface of steel gear can produce sintering and wearing and tearing when reaching certain temperature, reduce the smoothness of gear surface and the contour accuracy of gear, thereby increased machine noise and vibrations at the volley.People adopt the method for grease and oil lubricating to alleviate noise and vibrations usually, increase the lubricity of gear greater than 1000 rev/mins of general modes that adopt grease under less than 3500 rev/mins situation at last axle rotating speed; Last axle rotating speed greater than the next mode that adopts cup oil dripping or automatic spray oil of 3500 rev/mins situation reduce gear at the volley temperature and increase its lubricity.Above-mentioned two kinds of modes are that present mechanical industry mostly adopts.But it has certain defective, even be exactly that the steel gear is processed well again, precision is high again, its surperficial roughness always exists, and the existence of roughness will produce gear wear, machine grease and machine oil after using the regular hour is can blackening thinning, and wearing and tearing are inevitable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bevel gear that is used for high-speed industrial sewing machine, and the described this bevel gear that is used for high-speed industrial sewing machine will solve on the prior art high speed industrial sewing machine technical problem of gear drive wearing and tearing between axle and lower shaft, noise and vibrations.

Further, described bevel gear body is fixedly installed on the excircle of steel-making inserting part, the central axis of described bevel gear body and the central axes of steel-making inserting part.
Further, described bevel gear body is fixedly installed on the excircle of steel-making inserting part, the central axis of described bevel gear body and the central axes of steel-making inserting part.
Further, described bevel gear body axially has a columned extension along it, and described steel-making inserting part fixedly installs in the described extension, described steel-making inserting part be axially perpendicular to described extension axially.
Further, described steel-making inserting part is provided with the hole, described hole be axially perpendicular to described steel-making inserting part axially.
Further, the inboard of described steel-making inserting part is provided with screw thread.
The present invention also provides a kind of method of making the above-mentioned bevel gear that is used for high-speed industrial sewing machine, comprise in the described method one with high-abrasive material by thermoplastic processing method or the step of thermosetting processing method pressure injection on steel-making inserting part, in described step, the temperature of pressure injection is between 270 ℃～285 ℃, and the high-abrasive material one-shot forming is the bevel gear body.
Concrete, described thermoplastic processing method or thermosetting processing method adopt known technology of the prior art, relevant above-mentioned known technology, and those skilled in the art all knows, so do not repeat them here.
The present invention compared with the prior art, its effect is actively and significantly.The present invention is because the nonmetallic wear-resistant material self that adopts has intensity, rigidity and greasy property, on the surface that after friction after a while, itself material is adhered to another adjacent gear, extremely small coarse place in the contact-making surface is is separately filled and led up, thereby reach smooth to smooth movement effects, make coefficient of friction near zero, motion between similar ice and the ice, adopt a pair of gear of the present invention or in gear train, adopt a gear of the present invention under less than 10000 rev/mins condition less than 450 watts of rotating speeds at transmitted power, just can realize the gear use of on high-speed industrial sewing machine, working under the condition of no any lubricating oil in axle and the following shaft transmission.Low cost of manufacture of the present invention has been saved heat treatment and the mill processing of spreading out, as long as hold mould the one-shot forming of successfully employing high-abrasive material, precision is below 0.01; Do not need to lubricate, material has self lubricity, therefore can work under the situation of not having oil, has saved grease and machine oil, avoids greasy dirt to influence clothing; Its density is 1/7 of steel, because in light weight, so movement inertia is little, shakes for a short time, and noise is low; Coefficient of friction approaches zero, so it is little to wear and tear, and long service life.
