Abstract

Composite worm gears having little residual stress are prepared by forming a tube of synthetic resin by extrusion, compression molding, or centrifugal processing, and fixing the tube thus produced or rings cut therefrom onto a boss or core, preferably of metal. The process allows high performance high molecular weight thermoplastics to be employed.

Description

Electronic power assist steering worm gears
Technical field
The present invention relates to plastics mixing worm gear (worm gear) and adopt the particularly manufacturing process of the worm gear base of the wheel rim of thermoplastic material of synthetic material.
Background technology
At present, many dissimilar worm/worm gear sets in electrical power steering system (EPS), have been used.For the reason that reduces noise, reduction coefficient of friction and wear reduction, the wrom tooth part of one of these parts or these parts is preferably worm gear usually by synthetic or thermoplastic material manufacturing.
At present, there are two kinds of technology to be used to produce Worm gear mechanism.Such worm gear can comprise the monomer cast nylon ring of PA6 or PA6/PA12 mixture, and its pressure or casting are being on the hub (metal wheel hub) of metal substantially, and by induction heating melting together.
The shortcoming of above-mentioned technology is that this nylon ring is only just available when temperature is lower than about 80 ℃.Yet, if this product for example worm gear be used in the motor box of vehicle or have in the other environment of higher temperature, just can not adopt such product.
The synthetic material that the worm gear of another kind of type fills up or do not fill up by injection moulding is produced, and wherein, such synthetic material is usually based on polyamide (PA) 6,6.6,4.6,12, PPA (phenylpropanolamine) or its mixture; And polyphenylene sulfide (PPS); Polyamide-imide resin (PAI); And polyether-ether-ketone (PEEK); And directly fixing (by moulded section) is to the hub that has metal structure usually.In both cases, need one or many heat treatment to reduce the stress in the product and/or obtain the dimensional stability of required finished product.
The shortcoming of above-mentioned technology is that it is that worm gear is not withstand voltage to extend to the needed length of above-mentioned application that injection molding technique causes product.
Many such technologies or product are described in the prior art, for example, JP-A-2002/172703 " synthetic resin and manufacture method thereof " with metal hubs, JP-A-2002/079581 " manufacture method " with metal hubs resin formed article, JP-A-2002/370290 " method of fixing metal hub to the thermoplastic resin moulding product ", JP-A-2003/118006 " resin formed article and manufacture method thereof " with metal hubs.
DE-A-101 27 224 has disclosed the method that worm gear is fabricated to metal core by thermoplastic shaping technology.Yet this technology comprises all shortcomings of prior art.In JP-A-2002/248649, comprise similar announcement.Therefore, be desirable to provide a kind of worm gear manufacturing process of the defective of the technology that discloses in the past that do not have.
Summary of the invention
Target of the present invention provides and comprises still less step and/or have the production technology of higher-quality worm gear spare.This and other target provide by a technology, this process using the pipe made of extruding technology.According to a first aspect of the invention, target of the present invention comprises that by formation the technology and the outer part of synthetic resin of the goods of wheel hub reach, wherein, this wheel hub is metal or contain metal wheel-hub preferably, be somebody's turn to do the preferably outer part of thermoplastic resin of outer part, and periphery around this metal wheel hub, this processing step comprises: (a) extrude, compression forming or centrifugal pipe processing, then be machined into required size alternatively, (b) with suitable length from manage downcut ring and (c) the fixing ring that produces by step (b) to this wheel hub.As the present invention result in principle, this technology will make product have lower internal stress level and better dimensional stability; Owing to have higher molecular weight than injection moulding, therefore have higher wearability; And lower production cost.
According to a further aspect in the invention, target of the present invention preferably includes metal wheel hub by formation or contains the goods of metal wheel-hub and the outer part of synthetic resin reaches, wherein, should be preferably the outer part of thermoplastic synthetic resin by outer part, and periphery around this metal wheel hub, this embodiment comprises step: (a) extrude, compression forming or centrifugal pipe processing, and be aided with machining steps alternatively, (b) the fixing pipe that is produced by step (a) downcuts ring with suitable length from the pipe that is fixed on the preformed nuclear to preformed nuclear and (c).
Description of drawings
Fig. 1 illustrates one embodiment of the present of invention, and wherein, the extrusion resin material cuts off the back and combines with becket, and
Fig. 2 illustrates another embodiment of the present invention, wherein, and cutting after the extrusion resin material directly combines with metallic rod.
The specific embodiment
Above-mentioned two embodiment allow pipe to produce with different materials and its prescription, for example, and inserts, lubricant, copolymer, reinforcing fiber etc., but be not limited thereto.Preferred material comprises above-mentioned PA sill, POM (polyformaldehyde), PPA (phenylpropanolamine), PPO (polyphenylene oxide), PPS (polyphenylene sulfide), PEEK (polyether-ether-ketone), PAEK (PAEK) and PEKK (PEKK), PAI (polyimides) and LCP (liquid crystal polymer).Equally, can extrude with the mixing of multiple material or prescription and obtain the optimal properties relevant with the function of special layers, for example, gear layer and be beneficial to the layer that is connected on the metal hubs.Extrude and make the material utilize high heat capacity satisfy more demand application with centrifugal mo(u)lding to become possibility than the material that obtains with monomer monomer cast nylon 6 or nylon 12.
The further details of target of the present invention, feature and advantage can obtain from the description of relevant drawings, for example, have wherein explained according to two kinds of methods of the present invention.
An application of the product by explained hereafter of the present invention is suitable for use in the worm gear of EPS system.Such worm gear is listed in " security " in auto industry.Therefore, the manufacturer of EPS system need not have the material and the product of internal stress, to help the anti-damage of locking system between the operating period.The product of producing the technology (extrude, compression forming and centrifugal processing) of pipe and providing with thermoplastic material described here all has very low stress level, thereby can satisfy the aforementioned needs of auto industry.Particularly, when comparing with injection-molded product, technology of the present invention is owing to providing higher level of security to demonstrate tangible advantage.
In auto industry, " under the hood (automotive hood) " that the EPS system is placed near engine is a trend.Therefore, all parts of EPS system all are exposed under the high temperature, and this temperature typically is higher than 120 ℃.Therefore, because its physics and thermal characteristics, standard polyamides can not be used in this application.Based on same reason, also no longer select pipe by the polyamide 6 casting, therefore, the injection moulding temperature-resistanthermoplastic thermoplastic materials will be unique selection.The invention provides another kind of the selection, its tangible advantage is to have lower stress level than injection moulding.This comprises the possibility that can select from a large amount of temperature-resistant materials, to tackle specification requirement more specifically.
