Bearing housings for precision gears

It is known that the axles, for precision gears, for example for clocks, To store switching mechanisms and the like in plates, so-called circuit boards, in which the Lagerbohrunqen at the distance of the required tooth engagement are introduced. These plates for the bilateral Storage of the axles face each other and are through each other Spacer bolts attached. These standoffs are with the sinkers riveted, screwed or fastened in any other releasable or non-releasable manner.

According to the present invention, these spacer bolts consist of a plastic and are with the boards in the PreP or, Spritzvorganq; connected, In order to create a detachable connection, the Spacer bolts divided in their middle perpendicular to the longitudinal axis. the Invention enables the two parts to be joined together by one Druckknor. ^ like closure, in which, according to the invention, one part of the Bolt with a recess as a die and the other part lrait one appropriately shaped approach is designed as a male mold. Ur. the connection Reliable, tightly designed, the die is narrowed at its outer edge and the patrix on the. the part facing the bolt tapers. When these parts are put together, a button-like function is created, which by appropriately dimensioning the male and female molds requirements for the connection are sufficient,

In the accompanying drawing, the subject of the invention is shown in the Figu · * Ό shown in the view from the side, in the figure 2) in the plan view of a circuit board, Fig. 3) shows dii> both boards in the separated state. Figure 4) shows the two parts of the distance bolt on an enlarged scale, the die shown in section will.
