The fixing ring can be simplely fitted. A special device can fit the fixing ring in a very narrow circumstance effectively.
Description
The present invention relates to a kind of retaining ring.
Adopt this class retaining ring for example can be in a hole fixing stepped shaft vertically.Known Round Steel Wire bail wire in prior art (for example DE 26 20 142 C3) for this reason.This class is used for that axle or the Round Steel Wire bail wire in hole are in radial compression in the mounting groove in axle or hole or radially during open stress, by being inserted in vertically or inserting, corresponding machine parts can be installed, by means of this bail wire, when they are in radially off-load and insert under the state in the locking groove on machine parts, can fix this machine parts with locating vertically.In addition, the end of this Round Steel Wire bail wire, it is maybe outwardly-bent when being used for the hole to curve inwardly when being used for spool, and bending reaches the about 10% of ring length, makes overhang bracket on bottom land and keep the Round Steel Wire bail wire concentric with respect to its mounting groove basically.
By the known a kind of collar of DE 36 35 020C2 by Spring Steel Wire system, the end of knuckle in it is oriented.This collar state that elasticity struts by the groove that is slidably mounted on lock washer in, the end of its knuckle is entered in the axial vacancy on the lock washer.This preassembled assembly of forming by lock washer and snap ring, be pushed into during assembling in the cylinder blanket, at this moment, collar radially is clamped to such degree by means of anchor clamps that act on the knuckle end, that is, collar is fully hidden in the lock washer groove in the process that pushes.After this pre-assembled component axially locating, collar radially opens again, thus the part of collar in the groove of lock washer, a part in the circular groove of cylinder blanket, thereby by the mode fixed stop packing ring vertically of expection.
Introduced a kind of removable connection of two case members among the DE 125109182, wherein, on the cylindrical additional sections excircle of a housing parts annular groove is arranged, another housing parts holds the annular groove that has radially to join with first annular groove on the cylinder hole wall of this additional sections.In these two annular grooves an oval-shaped ring-shaped article is arranged, it has ring at disassembly status, and has a diameter between the diameter of two annular groove bottoms.In installment state, this ring-shaped article is pressed into ellipse by two screws of 180 ° of staggering each other, wherein have in the outer end of hole wall an expansion, with the diameter of roomy gap around this additional sections.This removable connection can be born bigger axial force.Yet its manufacturing is relatively more expensive, because must process the screw thread that is used for two clamping screws, and clamping screw must be screwed in its screw thread.
If for the ability to bear of axial force and the higher requirement of assembling proposition easily, the axle snap ring that then uses sheet stamping to become is shaped on the hole that is used to insert anchor clamps in the end of snap ring.
This class axle snap ring has the cross section that changes along the circumference of axle snap ring usually.The cross section of end basically with the same size at the middle part.Consequently, this class snap ring becomes ellipse in compressive state.Therefore these snap rings can not be used on the very narrow assembly condition.
In addition, in this class axle snap ring must be installed in gap narrow and small between a step axle and the cylindrical hole or when splitting out therefrom, because general installation pincers skid off from the hole of axle snap ring easily and can produce difficulty.Moreover this situation equally also appears in the axle snap ring of the crooked ring end of having of steel wire making.The axle snap ring often enter in the annular space between step axle and cylindrical hole some centimetres dark.This just makes operation very difficult.Best, an axle snap ring that snaps in the circular groove often snaps in the circular groove in hole dearly, so that be used to insert the hole of anchor clamps or at the eye that the knuckle end forms, covered in by the annular groove side partly.Consequently make the anchor clamps of axle snap ring can not or be difficult to catch this snap ring.
Therefore, the objective of the invention is, prepare a kind of retaining ring of assembling and decomposing can be convenient to.
For reaching this purpose, design a kind of retaining ring that a toroidal is arranged basically when not stressing, it has the ring end of two spacings that separate each other; There is one at least along 150 ° of constant basically diameters of its circumference and cross section; And in each ring petiolarea, a breach that opens wide towards its inner circumference is arranged.
Therefore, anchor clamps can insert in the breach of ring end reliably, and breach can enough extend in anchor ring greatly, and anchor clamps can be inserted without difficulty.By identical cross section being arranged along the long section of retaining ring, prevented that effectively the ring end from can imbed in the annular groove to such degree, that is, and anchor clamps no longer can insertion groove in.
By retaining ring of the present invention a kind of wonderful especially characteristic is arranged, that is, the axial force that retaining ring can bear is than similarly the axle snap ring is big.
Another exceeds unexpected effect and is by retaining ring of the present invention, and retaining ring keeps the shape of its annulus basically when reeling two ring ends, has less diameter.
In a kind of best form of implementation of retaining ring, the zone that cross section is constant basically, cross section is rectangle, square, circle or oval-shaped, this zone is symmetrical with respect to the ring end.
