Abstract

MECHANICAL. SUPPORT AND TIGHTENING RING FOR RETAINING MECHANICAL PARTS ON A SHAFT 6, CHARACTERIZED IN THAT IT INCLUDES TWO HALF RINGS 2 AND 3 WITH TRAPEZOIDAL SECTION, MEANS 4 AND 5 FOR COUPLING THE HALF RINGS, EACH HALF-RING BEING PROVIDED, ON ITS INTERNAL EDGE, WITH AN INCLINED RAMP COOPERATING WITH A CORRESPONDING RAMP PRACTICED IN A THROAT OF TREE 6.

Description

The present invention relates to a ring of appli-

  and tightening for mechanical use.

  Currently, to ensure the support and / or the tightening of mechanical parts on a tree, there are few systems or mechanisms which constitute, at the same time, means both

  support than clamping. The means most generally used

  support are the shoulders formed from a

  diameter tree given from a bar of greater diameter

  and the rings, Seeger type, which, however, not only

  can not withstand high axial thrusts, but ne-

  often occur, for example in the presence of

  balls, a support ring because of the connection radius of-

  said bearing. For tightening, the only known system is to thread the shaft, to use a nut or a collar. It is

  It is obvious that in all the systems examined

  the costly, quality materials for all devices used, and in any case, the simultaneous use of different solutions on the one hand, to achieve support and on the other , to realize the

Tightening.

  The object of the present invention is to enable

  to achieve a means of simultaneously assuring the role of

  and the role of tightening, without the need to make changes to one or the other function. In addition, there is no need for precision machining or special importance on the shaft, which reduces the cost considerably. For this purpose, a metal ring is provided consisting of two half-rings each ending in a

  ear at each end; the two ears of each

  that half-ring being traversed by holes of which one is threaded. On assembly, the half-rings are placed so that the smooth hole of an element coincides with the threaded hole of

the other element.

  In this way, the coupling is achieved by means of

  in two screws (for example with hexagonal head) placed

  one on one side and the other on the other side of the two half

  rings. The two half-rings have a chamfered rectangular trapezoidal section to form, on the inner edge, an inclined ramp which will cooperate with a groove of a corresponding profile made in the shaft. With such a configuration, when the two screws are tightened, the two half-rings come together and, as the

  throat and the half-rings comprise corresponding ramps

  inclined dantes, the ring moves in the axial direction

  on the tree, at the same time providing support and tightening.

  op The invention will now be described with more

  details with reference to a particular embodiment

  bind, given by way of example only, and shown in the accompanying drawings, in which: FIG. 1 is a side view, partly in section,

of the ring.

  Fig. 2 is a corresponding elevation view.

  Fig. 3 represents the device applied to a case,

  example, the fitting of two

  and a gear on a shaft, the upper part showing the classic assembly with ring type Seeger and

  collar, while the lower part represents the

  with two rings according to the invention.

  Fig. 4 shows, in detail, the coupling surfaces

between ring and tree.-

  The ring consists of two half-rings 2 and 3 and is tightened by the screws 4 and 5 on a shaft 6 at a groove 7. The inclined profile 8 of the half-ring 3 slides on the

  9 of the groove 7, which constitutes either a stop of ap-

  can be a spacer 10, a clamping member vis-à-

screw of said spacer 10.

  FIG. 3 represents, in its upper part, an assembly of known type constituted by the "Seeger" type ring 11 which constitutes the head support for the assembly constituted by the ring 12 of the ball bearing 13, the spacer 14, the gear 15, the spacer 10 and the collar 1-6 which ensures

the tightening.

  The same result is obtained with the two rings 17 and 18 used respectively as support and clamping elements, as shown in the lower part of the

figure 3.

  Of course, the invention is not limited to the embodiment which has just been described and which has been shown in the accompanying drawings. We can make many modifications of details without leaving, for that,

of the scope of the present invention.
