Abstract
The invention relates to a rubber sheath (3). The rubber sheath (3) is used on a port tire ring (2), and can prevent a rim (1) from being worn and prevent a tire from sliding. The sheath is arranged between the port tire ring (2) and the rim (1) and comprises two substrates (5) and a fiber cord fabric (4) clamped between the two substrates; and the two substrates (5) and the fiber cord fabric (4) are jointed by vulcanization at high temperature and high pressure. The two substrates (5) are made of rubber. The fiber cord fabric (4) comprises two fiber cord fabric layers. The rubber comprises the following components in percentage by weight: 30-40% of natural rubber, 12-18% of butadiene rubber, 3.5-4% of vulcanizing activator, 3-3.5% of rubber antioxidant, 1.5-3% of rubber vulcanizing agent, 35-40% of N550 and 2.5% of aromatic oil.
Description
Technical field
The present invention relates to a kind ofly to be used on the tyre bead of harbour, can prevent the wheel rim wearing and tearing, prevent the rubber sheath of tyre slip.This sheath will be assembled between tire bead and wheel rim, solve mainly that circle that the front handling mobile crane vehicle causes at work splits and tire and wheel rim between produce the problem of slippage.
Background technology
Raising along with port construction and freight container load-carrying capacity, load-carrying capacity to the harbour front carrier tire requires also to increase accordingly, but tire bead distortion can occur under case of heavy load, cause the cutting of tire bead and rim edge, can produce between wheel rim and tire in tire startup, brake process under case of heavy load on the other hand and skid, reduce the performance accuracy of equipment operation and stacking container.
Summary of the invention
In order to solve the described technical matters of background technology part at specification sheets of the present invention, the invention provides a kind of rubber sheath that is used on the tyre bead of harbour, described sheath is arranged between harbour tyre bead and wheel rim, and described sheath comprises: two substrates; Be interposed in the fibre curtain layer of cloth between described two substrates.Sheath with structure like this according to the present invention can prevent the wheel rim wearing and tearing effectively, and can prevent tyre slip.
Preferably, described two substrates and described fibre curtain layer of cloth are bonded together by vulcanizing under high temperature and high pressure.
Preferably, described two substrates are made by rubber.
Preferably, described fibre curtain layer of cloth is two-layer fibre curtain layer of cloth.
Preferably, described substrate (5) and fibre curtain layer of cloth (4) in temperature is the high temperature range of 155 to 160 degrees centigrade, pressure is to vulcanize in the high pressure range of 155 to 165 tons.
Preferably, described rubber comprises: the vulcanization activator that percentage by weight is the natural gum of 30-40%, cis-butadiene cement that percentage by weight is 12-18%, percentage by weight is 3.5-4%, the rubber antioxidant that percentage by weight is 3-3.5%, vulcanizer that percentage by weight is 1.5-3%, N550, percentage by weight that percentage by weight is 35-40% are 2.5% aromatic naphtha.
Description of drawings
With reference to schematic figures, by the following explanation given to non-limiting example, the feature and advantage that are used in the rubber sheath on the tyre bead of harbour according to the present invention will be clearer, wherein:
Fig. 1 shows according to the coordinate schematic diagram of rubber sheath of the present invention (3) with wheel rim (1) and tyre bead (2).
Fig. 2 shows the structural representation according to rubber sheath of the present invention (3).
The specific embodiment
In connection with accompanying drawing, rubber sheath structure of the present invention is elaborated hereinafter.
Fig. 1 shows according to the coordinate schematic diagram of rubber sheath of the present invention (3) with wheel rim (1) and tyre bead (2).As shown in Figure 1, sheath (3) is arranged between harbour tyre bead (2) and wheel rim (1), weares and teares to prevent wheel rim (1), and plays the effect that prevents tyre slip.
As described in Figure 2, comprising according to sheath of the present invention (3): two substrates (5); And be interposed in fibre curtain layer of cloth (4) between these two substrates.Preferably, described substrate is made by rubber.Described substrate need to be with multiple raw MAT'L (natural gum, carbon black, sulphur etc.) carry out repeatedly mixing rear formation in mill, to prepare simultaneously the fibre curtain layer of cloth (nylon 6-930d/tex) that width is about length 1/3, the fibre curtain layer of cloth is clipped in substrate, then preferably, carry out high temperature, high pressure sulfuration in the vulcanizing press of 160 tons, thereby make described substrate (5) and the fibre curtain layer of cloth (4) that is interposed in therebetween be bonded together.
Preferably, described substrate (5) is 10 to 15 minutes with the time of cure that fibre curtain layer of cloth (4) vulcanizes in vulcanizing press.
Preferably, described substrate (5) and fibre curtain layer of cloth (4) in temperature is the high temperature range of 155 degrees centigrade to 160 degrees centigrade, pressure is to vulcanize in the high pressure range of 155 tons to 165 tons, thereby is bonded together.
In the present invention, preferably, can adopt the fibre curtain layer of cloth of 2 layers.
Because rubber sheath need to have special wear resisting property and higher hardness, therefore need to adjust its formula, increase the consumption of carbon black and vulcanizator.The material prescription of substrate that consists of this rubber sheath is as shown in table 1:
