Description
Technical field
The present invention relates to resin roller with built-in bearing and manufacture method thereof and manufacturing shaping die, this resin roller with built-in bearing is for example to be equipped in the roller of the conveying carrier of multistorey parking space with guide roller even load top load, and it is with the load top load and require the synthetic resin ratch tire of suitable elasticity and resistance to abrasion to be contained on the outer ring of bearing.
Background technology
At present, bearing as rotating part, ball-bearing casing has actual achievement for many years, to make inner ring, outer ring and ball respectively, and a plurality of balls are seated between inner ring and the outer ring make bearing, all make as gauge member, this gauge member meets standards such as the standardized international standards of each factor such as the shape of inner ring and outer ring, size.But, in recent years, among the intensifying of batch manufacturingization, rationalization, price competition, though the running condition of the bearing of industrial machine etc. is diversified, we can say that the bearing that can start with is the gauge member of international standard, therefore, have to the gauge member assembling application product of international standard.Like this, the manufacturing that the manufacturing conveyor line of bearing can not corresponding specialty goods can not adapt to diversified purposes.
As one of diversified application product, that purposes in recent years sharply enlarges, as bearing to be contained in inside tires resin roller with built-in bearing is arranged.Resin roller with built-in bearing is to make tire by ester moulding in the periphery of the iron hoop of making in advance at present, and after grinding tire, the inside that will be contained in iron hoop as the bearing set of gauge member constitutes.The resin roller with built-in bearing of the Zhi Zaoing operation that is used to make is a lot of like this, and price is very high.
The manufacture method of existing resin roller with built-in bearing such as Fig. 4～shown in Figure 6.Fig. 4 is the section-drawing of the intermediate that comprises iron hoop that ester moulding is used in the manufacturing of existing resin roller with built-in bearing, Fig. 5 is that expression is contained in the figure of the state in the intermediate shown in Figure 4 with bearing set, and Fig. 6 is that expression is ground the tire of resin roller with built-in bearing shown in Figure 5 and the figure that finishes the goods state that finishes.As Fig. 4～shown in Figure 6, in existing resin roller with built-in bearing, used as the iron hoop 40 of ester moulding with chipware.That is to say, make iron hoop 40 roughly cylindraceous in advance, so that bearing can be assembled in inside with size that the outer ring external diameter with bearing is complementary.Iron hoop 40 is to be used for bearing location and to constitute towards the integrally formed flange part 42 of radially inner side by cylindrical body 41 with at its axial side end.As the preparation of ester moulding, carry out the degreasing on iron hoop 40 surfaces, and, carry out the coating and the drying of twice lining cement outside on the diametric plane 43 repeatedly.
Then, with iron hoop 40 and shown in imaginary line by about the shaping die 49a, the metal pattern 48 that 49b constitutes cut apart assemble, aqueous resin such as thermohardening Polyurethane rubber is injected die cavity on the outer diametric plane 43 that is formed at main body 41, by making the hardening of resin tire 45 that is shaped.This operation needs about 30 minutes～1 hour.Give the elasticity and the resistance to abrasion of tire 45 necessity by adopting thermohardening Polyurethane rubber system goods.Then, from metal pattern 48, take out the iron hoop 40 that has tire 45, carry out the dry slaking of thermohardening Polyurethane rubber.This operation also needs about 8～10 hours.Owing to be formed at the pattern draft of shaping die 49a, 49b, unavoidably will produce outshot 46.The matched moulds portion of corresponding metal pattern 49a, 49b can produce the burr 47 of resin at the left and right sides of roller central part.Therefore, in order to remove outshot 46 and the burr 47 that ester moulding produces, grind the surface of tire 45.At last, will be as the parts of gauge member and the bearing of making in advance 51 is pressed into the inside that periphery is formed with the iron hoop 40 of tire 45, till flange part 42, thus, can assemble resin roller with built-in bearing.
As shown in Figure 5, bearing 51 by inner ring 53, outer ring 54 and be seated in inner ring 53 and outer ring 54 between a plurality of steel balls 57 as rolling body constitute.Ball 57 can roll along the track that is formed by rail groove 55 that is formed at inner ring 53 peripheries and the rail groove 56 that is formed at the interior week of outer ring 54.Space between inner ring 53 and outer ring 54 is injected with grease around ball 57, for preventing the leakage of grease, be provided with rubber system sealing member 58.For preventing that bearing 51 from deviating from from iron hoop 40, be pressed in outer ring 54 under the in-to-in state of iron hoop 40, the part in the outside of outer ring 54 with respect to inner peripheral surface 44 ca(u)lks, is formed removal stop section 59.From state shown in Figure 5, the outer peripheral face of tire 45 is processed by resin ground, forms on the barrel surface 50.The resin roller with built-in bearing of finishing as shown in Figure 6.
For example following the carrying out of forming synthetic resin of Polyurethane rubber etc.Mix after deaeration being liquid resin and hardener, and under the liquid state of maintenance, be injected into model, the underhardening stage demoulding after adding sulphur to a certain degree further adds sulphur then, carries out the second hardening operation.In this ester moulding, the temperature of reaction of injecting resin is higher, even can reach 120 ℃～150 ℃, and the curing time that is used to add the sulphur sclerosis is longer than other synthetic resin, is about 1000 minutes.
Also considered not use iron hoop 40, and made the outer peripheral face of outer ring 54 of resin direct contact standard rolling bearing 51 and the situation of shaping tire.But,, then can produce following unfavorable condition if only make the tire direct forming having finished on the stack-mounted outer ring 54 as bearing 51.That is to say that because the outer peripheral face of outer ring 54 is ground very totally, beautiful, so after the degreasing, even adhesive-applying, resin also is difficult to adhesion, tire 54 is peeled off from the outer ring easily.In metal pattern 48, since through making resin cooling for a long time after, hi-heat resin is acted directly on the outer ring 54, therefore, the rubber system sealing member 58 of bearing 51 might be under the high temperature and damaged, simultaneously, is the grease that lubricated ball 57 injects, the increase of high temperature current downflow might be flowed out to the outside from damaged sealing member 58.When in order to remove the outshot 46 that produces because of shaping die 49a, 49b and burr 47 and to grind, grind the resin-oatmeal that produces and can invade bearings 51 inside from damaged sealing member 58, can not obtain can be for practical roller.And, because it is different with the shaping of injection machine, it is the shaping of being undertaken by metal pattern 48, so can not carry out correct ester moulding in the periphery of the outer ring 54 of bearing 51, simultaneously, also might invade the inside of bearing 51 by the resin that metal pattern 48 flows out, bearing 51 can not be rotated.
Like this, outside as the outer ring of the bearing of the gauge member of standard, be difficult on the diametric plane directly with ester mouldings such as thermohardening Polyurethane rubber, when using standard rolling bearing, have to as the ester moulding chipware, outside the outer ring, make iron hoop more in advance, adopt ester moulding on iron hoop, bearing is pressed into this iron hoop in-to-in method.Adopt iron hoop to carry out ester moulding, can add the external diameter of big roller, simultaneously,, be used for component count and the manufacturing cost that resin roller with built-in bearing is made so can increase owing to will make iron hoop in addition.
The problem to be solved in the present invention is: in the inside tires that the ester moulding by thermohardening Polyurethane rubber etc. obtains is equipped with the resin roller with built-in bearing of bearing and makes, just can correspondence small-sized and require high-intensity purposes with iron hoop without ester moulding.
