Embodiment Construction

[0028] exist figure 1 The exploded view in shows the first gear half 2 which is fastened to the shaft end 21 of the camshaft 20 . The first gear half 2 has a flange 4 extending in the axial direction. The second gear half 3 is pushed onto the flange 4 in the axial direction for fitting the gear. Arranged between the two gear halves is a spring element 14 which, when assembled, is supported on the first gear half 2 on the one hand and on the second gear half 3 on the other hand. In the mounted state, the two gear halves are clamped against each other by the spring element 14 in a known manner.

[0029]If the second gear half 3 is pushed onto the flange 4 , the two gear halves 2 , 3 are fastened to the shaft end 21 of the camshaft 20 . Of course it is also possible first to fasten the first gear half 2 to the shaft end 21 and then to mount the second gear half 3 with the elastic element 14 . According to the invention, the annular disk 8 serving as the fastening element 6 is...

Abstract

The invention relates to a divided toothed wheel (1) having two toothed wheel halves (2, 3) which are tensioned in relation to each other. The first toothed wheel half (2) comprises a hollow cylindrical collar (4), to which the second toothed wheel half (3) is secured by means of a securing element (6). The aim of the invention is to produce such a divided toothed wheel which only occupies a minimum amount of space from the axial direction and has two halves which are permanently connected together. In order to achieve this, the securing element (6) is designed as an elastically shapeable annular ring disk (8). Said annular ring disk (8) comprises slots (7) which are distributed over the periphery and extend radially outwards from a central opening (5) forming spring tongues (9) between the slots (7). The free ends of the spring tongues (9) have edges (10) that sit on the outer circumference of a component (B) arranged in the central opening (5), in a form-fitting manner, as the spring tongues (9) spring back after the annular ring disk (8) has pressed against the second toothed wheel half (3).

Description

technical field [0001] The invention relates to a split gear (geteiltes Zahnrad) with two gear halves clamped to each other, wherein the first gear half has a hollow cylindrical flange (Bund), the second gear half is fastened by means of a fixing element. The gear halves are secured to the flanges. Background technique [0002] In the case of shafts driven by gear transmission, such as camshafts or balance shafts, which rotate at half or twice the engine speed in operation, it is known to apply split gear halves with mutually clamped gear halves, respectively Gears replace simple one-piece gears as drive elements. The backlash-free clamping of the gears avoids unwanted noise generation, which can occur empirically when using single-piece gears due to backlash. [0003] Document EP 0 205 156 B1 discloses a split gear consisting of a first gear part and a second gear part, wherein the gear parts are clamped against each other by an omega-shaped spring. The first gear part h...
