Definitions
- the invention relates to a sealing arrangement on hinge joints of caterpillar tracks, the joint consisting of a bolt and a bushing, to which bolt the outer chain links and to the bushing the inner chain links are fastened, the bolt having an available lubricant reservoir, in particular via a transverse channel with the lubricating gap between the bushing and the bolt is connected, which is sealed at its ends by seals which are supported on the outer chain links on the one hand and on the bushing ends on the other hand, with a dimensionally stable support element being arranged between the bushing end and the outer chain link .
- Such a sealing arrangement is known, for example, from DE 31 27 104 C2.
- a support ring is arranged between the bush ends in a corresponding receiving cavity of the outer link parts on the bolt with play, on the outside of which the actual ring elastic seal sits.
- the seal is supported with its sealing elements or legs on the one hand on parts of the outer chain link and on the other hand on the socket end face.
- it is necessary to lubricate the joints which according to the prior art is carried out by filling a bushing / bolt combination with lubricant, whereby a lubricating space in the joint area is provided by the arrangement of a support ring / seal combination between bushing, bolt and chain link arises.
- Sealing arrangements are known, flowable lubricants being used as the lubricant, and also sealing arrangements in which the lubricant reservoir is formed by the chamber in which the seal is arranged. Grease or the like becomes less flowable as a lubricant Material used.
- the lubricating gap between the bushing and the bolt is filled with grease, and likewise the chamber in which the seal is arranged, specifically in the region facing the lubricating gap.
- the lubricant reservoir in the bolt itself is eliminated, so that the bolt can be designed as a solid part without a cavity.
- the object of the invention is to create a sealing arrangement of the generic type, in which the forces occurring in the joint are essentially restricted to a connection between the bushing and the chain link.
- the invention proposes that the support element is integrally formed on the socket ends and the lubricating gap with which
- Gasket-receiving space is connected via lubrication grooves or lubrication channels, which in the end face of the molded support elements and / or in the bushing body are formed, and / or lubricating holes or channels extending through the bush body are formed, by means of which the lubricating gap is connected to the sealing space.
- the seal makes it possible for the seal to be arranged directly between the bushing and the outer chain link, without an additional support ring or other comparable elements having to be arranged in the joint space, which could bring about frictional engagement.
- the bushings are designed at their ends so that when the outer chain links are pressed to a bolt dimension, a pressure-dependent frictional connection can be achieved between the bushing and the outer chain link and a sealing space results between the outer chain link and the bushing appropriately trained seal ensures the sealing of the joint in this area.
- the sufficient supply of lubricant is alternatively or in combination achieved that radial lubrication grooves are arranged and formed on the end faces of the bushing projections, or that penetration holes or channels penetrating the bushing body are formed, by means of which the lubricating gap with the sealing space in Connection is established.
- the design of the seal itself is to be adapted to the spatial conditions and geometric conditions, the seal space between the chain link and bushing being able to be used as well as possible by the seal.
- a suitable and permanent design of the seal on the labyrinth contact surface of the chain link and the corresponding partial section of the bush contact surface can ensure a perfect and permanent seal.
- a roundest ring made of elastic material is considered as the simplest solution for the seal, other seal forms and combinations of seal materials (elastomer materials) being possible.
- the end face of the integrally formed support elements is directed at right angles to the bushing axis.
- the surface of the bushing located between the end face of the support elements and the bushing jacket is designed to spring back in relation to the end face, the area of the outer chain links forming the seal receiving cavity extending in the axial direction beyond the beginning of the cylindrical jacket surface of the bushing is sufficient and the socket is at least slightly overlapped by the cavity parts of the outer members with radial clearance.
- the recess between the end face and the sleeve shell is designed to be stepless.
- transition surface between the end surface and the sleeve casing can be designed as an inclined surface or as a concave or convex curved surface.
- seals are vulcanized onto the walls of the outer chain link or the bush surrounding their receiving space, wherein the seals consist entirely or at least partially of vulcanizable material.
- This design makes it possible to vulcanize the seal on the wall of the outer chain link or the bushing before the assembly of the individual parts, so that there is firm cohesion before assembly and in addition the seal only has a surface that is stressed by relative movements, namely the surface , which is supported on the other component.
- the arrangement is preferably such that the seal on the wall of the outer space surrounding the receiving space Chain link is vulcanized.
- FIG. 1 shows schematically a hinge joint of a track chain with a sealing arrangement
- the hinge joint consists of two outer chain links 1, two inner chain links 2, a bolt 3 and a bushing 4.
- the outer chain links 1 are connected to the bolt 3, for example in the form of a shrink connection, while the inner chain links 2 in are connected to the socket 4 accordingly.
- the bolt 3 has a bore 5 which is open on one side and serves as a lubricant reservoir.
- the bore 5 is connected via a transverse channel 6 to a gap between the bushing 4 and the bolt 3, which gap is in turn connected to sealing arrangements 8 which are arranged in a cavity in the outer chain links 1.
- the seals 8 prevent the lubricant from escaping to the outside.
- a dimensionally stable support element is formed, which is integrally formed on the socket ends.
- the lubrication gap 7 is connected to the space 10 receiving the seal via lubrication grooves or lubrication channels 11.
- the lubrication grooves are optionally formed radially on the end face of the support element 9, while the lubrication holes pass through the bushing body and the connection between the Make the lubrication gap 7 and the cavity 10.
- the end face of the integrally formed support elements 9 is directed at right angles to the bush axis, that is to say parallel to the face of the cavity 10 of the outer chain link 1 which is directed at right angles to the bush axis.
- the recess between the end face of the support element 9 and the socket jacket of the socket 4 is in the form of a step
- the recess is stepless, namely shown in FIG. 2 and in FIG. 1 on the left by an inclined surface, top right in Figure 1 by a concave Surface and in Figure 1 bottom right through a convex surface.
- the surface configuration is arbitrary, but must be adapted to the seal.
- the shape of the seals 8 is also arbitrary, as is the possibility of producing the seals from a uniform elastomer material or from elastomer component materials.
- the seals 8 are preferably on the outer walls surrounding their receiving space 10
- Chain link 1 vulcanized, wherein the seals consist completely or at least partially of vulcanizable material. From the sealing arrangement according to the invention there is the possibility of using previously conventional components which were used for the production of unshielded chains. In this arrangement, the area of the outer chain link 1 forming the seal-receiving cavity 10 extends in the radial direction only to such an extent that there is a play (gap) between the cylindrical outer surface area of the bush 4 which it engages and the overlapping wall area of the chain ⁇ member 1 remains.
