Abstract

The invention relates to a gearwheel. The wheel axis (24) is variable in angle in relation to the gear rim (2), by the gear rim (2) being connected by means of a connecting ring (6), the axial width of which is less, to at most 1 DIVIDED 3 as long, than or as the teeth (4) of the gear rim (2), to a ring part (8) which lies axially parallel and invariable in angle with respect to the wheel axis (24). <IMAGE>

Description

Zahnracl

The invention relates to a gear. The invention aims to achieve the object be solved, a uniform tooth load over the entire tooth length even then Always ensure if different points across the face width Radial forces occur.

This object is achieved in accordance with the characterization of patent claim 1.

Further features of the invention are contained in the subclaims.

An embodiment of the invention is described below with reference to FIG the drawing described. This shows an axial section through a gear according to FIG the invention.

The gear shown has a ring gear 2 with teeth 4, the over a connecting ring 6 with a Ring part 8 is connected. the The width of the connecting ring 6 is smaller than the axial width of the teeth 4.

The connecting ring 6 is axially-central halfway between the end faces 10 of the gear. The ring gear 2, the connecting ring 6 and the Ring part 8 together consist of a one-piece ring body 12. The connecting ring 6 is formed by in the end faces 10 of the gear wheel radially inside the ring gear of the teeth 4 annular grooves 14 are formed, the groove base 16 of which is the end faces of the connecting ring 6 wild. The ring part 8 is arranged axially one behind the other via two Radial roller bearings 18 and 20 distributed across the width of the gear wheel are mounted on a shaft 22. The raclaciise 24 is at the same time the axis of the wool 22 and of the ring part 8. Due to the roller bearings 18 and 20, the wheel axle 24 is axially parallel to an unchangeable angle arranged to the ring part 8. The ring gear 10 is, however, due to the resilient resilience of the material of the connecting ring 6 relative to the wheel axle 24 variable in angle. This means that when the while 22 tilting forces 26 act, the Shaft 22 with the wheel axle 24 with respect to the normally axially parallel teeth 4 to a certain angular offset, corresponding to the tilting forces 26 can. The ring part 8 remains parallel to the wheel axle 24 and to the axle 22, wherein these parts are relative to the ring gear: -2 corresponding to the stated angular offset adjust while the ring gear 2 maintains its original Lagc and its Teeth 4 continue to be evenly attached to the teeth 40 of one with over their entire length they are engaged further gear 42 rest.

Thus, yemass of the invention is obtained when tilting forces occur 26 at the same time also a pressure equalization.

Claims (3)

Claims 1. Gear, d u r c h g e n n z e 1 c h n e t that the wheel axle (24) is variable in angle relative to the ring gear (2) by the ring gear via a connecting ring (8), the axial width of which is smaller, up to is at most 1/3 as long1 as or as the teeth (4) of the ring gear, with a Ring part (8) is connected, which is axially parallel and angularly unchangeable to the wheel axis (24) lies. 2. Gear according to claim 1, characterized in that the ring gear (2), the connecting ring (6) and the ring part (8) together from a single piece Annular bodies (12) consist of annular grooves (14) on the end face, the groove base of which (16) the end faces of the connecting ring (6) form, and that the ring body at least is resiliently flexible in its area forming the connecting ring. 3. Gear according to claim 1 or 2, d a d u r c h g c k e n n z e i c h n c t that the ring part (8) via a radial roller bearing (18, 20) on a shaft (22) sits.
