Problems solved by technology

In particular, the use of rolling bearings has the disadvantage that the bearing device has a relatively high weight and that when the movable component is moved violently, as it is in the case of digital displays of watches, the watch component parts are heavily loaded and cause damage

Embodiment Construction

[0028] Figures 1 to 4 The unit shown in has a ring gear 1 with an internal toothing 2 which has six axially protruding flange segments 3 evenly distributed on its outer circumference. A slotted hole 4 extending in the circumferential direction is formed in each flange section 3 .

[0029] The flange section 3 has a greater thickness than the ring gear 1 , so that it protrudes axially from the ring gear 1 towards one side.

[0030] Arranged on the protruding end face of the flange section 3 is an annular hour disk 5 whose outer diameter is greater than the outer diameter at the flange section 3 and whose inner diameter is smaller than the internal toothing 2 of the toothed ring 1 diameter of. The protrusion of the flange section 3 forms an annular gap 12 between the toothed ring 1 and the hour disc 5 .

[0031] With the middle area of ​​the elongated hole 4 covered and having a diameter equal to the width of the elongated hole 4, a stepped through hole 6 is formed in the ho...

Abstract

The invention relates to a support device for a component which can rotate or carry out translational movements of a watch with a movement and at a fixed component of the watch. The movable component has one or more edges 14 extending along its path of movements with constant cross sections, which mutually spaced bearing rollers 20 with radially encircling grooves 21 on their radially circumferential peripheries are meshed into. Axes 19 extending perpendicular to the movement path of the movable component are provided. The bearing rollers 20 are freely rotatably around the axes. Eccentric bearing projections 16 axially adjoining the axis 19 are also provided, and are rotatably mounted adjustably in corresponding bearing recesses 15 of the fixed component of the watch under frictional resistance.

Description

technical field [0001] The invention relates to a bearing device for a rotationally or translationally movable component of a watch with a movement on a fixed component of the watch. Background technique [0002] It is known to use rolling bearings or sliding bearings for mounting components that can be moved in rotation or in translation. In particular, the use of rolling bearings has the disadvantage that the bearing device has a relatively high weight and that when the movable component moves violently, as in the case of digital displays for watches, the watch component parts are heavily loaded and cause damage. Contents of the invention [0003] It is therefore the object of the present invention to provide a bearing device of the type mentioned at the outset, which has a low weight while requiring little installation space and in which installation is simple and the adjustment effort is low. [0004] According to the invention, this object is achieved in a first solu...
