Abstract
The cylinder that rubber covers is made of three parts.The rubber of mesozone is partly measured reading on the meter in hardness, and is littler than the reading of the rubber part at two ends.Three rubber of cylinder partly are installed on the axle, under pressure state, two ends are partly vulcanized to the part of center, and the combined material that will vulcanize three partial rubber structures simultaneously bonds on the axle.
Description
The present invention relates to make the method for the cylinder that rubber covers.
United States Patent (USP) the 3rd, 666 discloses a kind of lining that has the center rubber covering layer No. 335, and the two ends hardness ratio of its rubber covering layer is higher.These ends not only can be carried out the pressure assembling but also can be glued on the sleeve of supporting.
United States Patent (USP) the 1st, 919 discloses a kind of rubber bearing structure No. 375, hard outer soft two-layer rubber size in this structure has.
United States Patent (USP) the 3rd, 118 discloses a kind of elastic parts No. 710, and its internal layer is a rubber parts and two outerly be working of plastics.
The present invention relates to a kind of method of making the cylinder of rubber covering, promptly rubber covering layer is set, and one outer rubber layer is set at every end of axle by middle body on axle.The middle body rubber covering layer, the reading of measuring on the meter in hardness is littler than the tectal reading at two ends.Pressure is applied on three rubber covering layers.This forces three cover layers closely to contact, and then with each cover layer vulcanizing treatment together, becomes an overall structure, and at the same time, the cover layer of this combination rubber is sticked with glue receive on the axle.
Accompanying drawing is the aforementioned profile that has the axle that makes up rubber covering layer.
The method of the cylinder that manufacturing rubber involved in the present invention covers follows these steps to finish.An axle 2 at first is provided, and it will be covered by rubber layer.Apply axle initial with glue-line 4, and this glue-line will bond to rubber covering layer on the axle finally.This glue is hot activity gel, usually uses in the prior art, also can adopt various bonding agent that rubber is connected on the metal.With ground floor elastomeric material 6 be placed on axle 2 centers above, the reading that this material is measured on the meter in hardness is 65.End cap 5 is contained in the two ends of axle, and tightens with bolt 3.Except surface 7, it has almost wrapped whole end faces of elastomeric material 6.Then, second and the 3rd elastomeric material are contained on the axle at rubber covering layer 6 two ends, these rubber covering layers 8 and 10 readings of measuring on the meter in hardness are 85, therefore, and general its hardness ratio rubber covering layer 6 height.Pressure puts on the end cap 11 by the direction of arrow 12, and three rubber covering layers are closely contacted, especially at surperficial 7 contact jaws.Be wrapped in all on the axle that covers by rubber with nylon tape 14, pressure is acted on rubber covering layer 6,8 and 10.Under pressure state, with total heating, sulfuration makes second and the 3rd rubber covering layer stick to the end 7 of first rubber covering layer.Sulfidation is by device being heated to 305 °F, carrying out in 1～3/4 hour.Simultaneously, hot activity gel 4 bonds to the combining structure of the elastomeric material that constitutes on the axle.In fact, the combination rubber structure is the two hard extremity pieces 8 that sulfide and 10 and soft rubber interlude 6.
Rubber covering layer 6,8 and 10 is rubber compounds of habitually practising, is that they have different hardness to unique key issue of its combination, and can cures.Used typical rubber compound all is listed in United States Patent (USP) the 3rd, 505, in No. 267.
Claims (1)
1, makes the method for the cylinder of rubber covering, comprise the steps:
(a) provide an axle that will be covered by rubber covering layer, this axle will apply with glue-line,
(b) on the center of axle, load onto in hardness and measure first less rubber covering layer of reading on the meter,
(c) in the zone, both ends of axle, load onto second and the 3rd bigger rubber covering layer of reading on hardness is measured,
(d) pressure is applied on the rubber covering layer at both ends, so that all three rubber covering layers closely contact,
(e) two ends of second and the 3rd rubber covering layer to first rubber covering layer are vulcanized in the axle heating that rubber is covered, and will make up rubber covering layer with glue and be bonded on the axle.
