Abstract
A sawtooth modular ball hinge and making and assembling method for the ball hinge are provided. The ball hinge comprises a metallic casing, a core shaft and an elastic rubber element. Between the metallic casing and the elastic rubber element, a metallic partition bushing is provided, which is in 2-flap structure; the metallic partition bushing and the core shaft are in sawtooth shape; the sawteeth of them are mutually nested, engaged and vulcanized together. After the metallic partition bushing and the elastic rubber element are vulcanized, comparing with former diameter, along the radial direction a rubber-metal vulcanizate with a clearance in between is formed. The making of the ball hinge rubber elastic element is: the metallic partition bushing, the core shaft and the elastic rubber are vulcanized under high temperature and pressure into a rubber-metal vulcanizate, then the rubber-metal vulcanizate is pressed into a metallic casing, this forms a finished product. As the rubber-metal vulcanizate is of a 2-flap structure, and is certain distance apart in radial direction comparing with former diameter, when the vulcanizate is pressed into the metallic casing, the rubber is pre-compressed; the pre-compression volume can be adjusted for the rubber by adjusting the apart distance in radial direction of the 2-flap partition bushing.
Description
Technical field
The invention belongs to a kind of damping means and assembling method thereof, be meant the ball hinged rubber elastic element product especially and make assembling method, be mainly used in the rubber elastic element that the bogie of various kinds of vehicles vehicle uses, also go for the position that any damping elastomer such as engineering machinery connects simultaneously.
Background technique
Ball hinged rubber elastic element is the compound damping element of using always of a kind of rubber-metal, can be widely used in various vibration dampings place, especially in the bogie of rolling stock, use very general, what wherein application was the most general is again the structure of three-major-items formula (metal-coating+rubber+mandrel), and this structure has its some characteristics, shortcoming is also arranged simultaneously, characteristics are uses that their performance can satisfy various operating modes substantially, shortcoming is, when the radial and axial ratio of rigidity of ball pivot required less than 5: 1, this structure had not required with regard to satisfying.
In the last few years, along with technological progress, developed the new structure of several energy realizations less than 5: 1 radial and axial ratio of rigidity requirement, but these new structures all are based on and design under the prerequisite of bigger installing space, when the product effective diameter less than 100 the time, just be difficult in when guaranteeing mandrel intensity and Security, design can reach 5: 1 in addition more path to the ball pivot of axial rigidity than structure.
Summary of the invention
The objective of the invention is to deficiency, provide a kind of ball hinged rubber elastic element precompression convenient at existing ball pivot, be easy to again to control pre compressed magnitude and radially, the new-typed ball bearing rubber elastic element and the making assembling method thereof of axial rigidity ratio.This kind ball pivot both mandrel intensity and Security is good, and radial and axial again rigidity specific energy reaches 5: 1.
The objective of the invention is to be achieved through the following technical solutions, a kind of ball hinged rubber elastic element and assembling method thereof, comprise metal-coating, mandrel and elastic rubbery body, its characteristics are: the metal spacer is arranged between metal-coating and elastic rubbery body, the metal spacer is two valve structures, and metal spacer and mandrel engrail, both sawtooth are inlayed mutually, interlock sulfides.It radially is to be separated into gapped rubber-metal sulfuration body that the metal spacer is compared with original diameter with elastic rubbery body sulfuration back.
The making of ball hinged rubber elastic element is after metal spacer, mandrel and elastic rubbery body are become a rubber-metal sulfuration body by high temperature, high pressure sulfuration back is bonding, again this rubber-metal sulfuration body to be pressed into metal-coating, finally becomes finished product.Because the metal spacer is two valve structures, and sulfuration back and original diameter have compared distance necessarily radially divided, and therefore when vulcanizing body and be pressed into metal-coating, rubber has just obtained precompression, adjust the radially divided distance of two lobe spacers, just can adjust the pre compressed magnitude of rubber.Concrete steps are as follows:
1, metal spacer, mandrel are processed into flexuose, and the metal spacer is cut into two valve structures;
2, metal spacer, mandrel are inserted in the vulcanizer, radial direction between metal spacer and mandrel forms certain clearance, elastic rubbery body is injected in the gap between metal spacer and the mandrel, after the sulfuration of high temperature, high pressure, make that metal spacer, mandrel and elastic rubbery body are bonding to become a rubber-metal to vulcanize body;
2, again this rubber-metal sulfuration body is pressed into metal-coating, finally becomes finished product.
Characteristics of the present invention are:
Ball hinged rubber elastic element comprises metal-coating, spacer and elastic rubbery body, elastic rubbery body is between metal spacer and metal mandrel, and the outer surface of elastic rubbery body and metal spacer bond together, the internal surface of elastic rubbery body and metal mandrel bond together, the outer surface of metal spacer is fitted in by interference fit with the internal surface of metal-coating, metal spacer and mandrel are processed into flexuose according to performance need, and both sawtooth are inlayed mutually, interlock, and the shape of sawtooth, size and quantity can be adjusted according to the product performance needs.Structurally mainly contain following characteristics:
1) because metal spacer and mandrel are processed into flexuose, the maximum position of mandrel is greater than the internal diameter of interior steel bushing, so the metal spacer must make splitted structure, can assemble and vulcanize.
2) because the metal spacer is designed to the distinguish formula, radially suitably separate during sulfuration, distinguish metal spacer closes up during installation, so rubber just can obtain certain precompression stress, thus the usability of raising ball pivot.
3) because flexuose design, thereby the inner rubber pad structure that has formed one or more parallel connections, thereby improve the axial rigidity of ball pivot greatly, reduced radial and axial ratio of rigidity.
When this novel ball hinged rubber elastic element can be very little at installing space (little of φ 80), can also realize radial and axial ratio of rigidity effectively less than 5: 1.
