Embodiment Construction

[0044] Figures 1 to 3 A transmission 10 according to the invention is shown, which has a transmission housing 16 enclosing a transmission chamber 12 of a bevel gear transmission 14 . The transmission housing 16 extends substantially rotationally symmetrically along a rotational axis 18 of the first shaft 20 , wherein the rotational axis 18 defines the longitudinal direction of the transmission 10 . The transmission chamber 12 is further divided into a first transmission chamber portion 22 substantially surrounding the first shaft 20 and a second transmission chamber portion 24 substantially surrounding a third shaft 26 arranged transversely and perpendicularly to the longitudinal direction. The transmission chamber areas 22 , 24 are arranged adjacent to each other in the longitudinal direction and have a common cylindrical transition area 28 which is arranged approximately in the middle of the longitudinal length of the transmission housing 16 and is arranged coaxially with t...

Abstract

The invention relates to a transmission arrangement (10). Said transmission arrangement (10) comprises a transmission housing (16), a transmission chamber (12) surrounded by the transmission housing (16), a first shaft (20) mounted in the transmission housing (16), a cavity (88) embodied in the first shaft (20) eccentrically to the rotational axis (18) with the cross-sectional centre of gravity thereof, and a channel (156) embodied in the first shaft (20). Said channel (156) connects the transmission chamber (12) to the cavity (88) of the first shaft (20). The aim of the invention is to improve the lubrication process of the transmission arrangement (10) and the operating reliability, thus extending the maintenance intervals. To this end, the channel (156) is provided with a component (162) which is used to reduce the passage cross-section of the channel (156), and by which means only an optimised quantity of lubricant is transported through the channel (156). One such transmission arrangement is used for example for driving a cutter on a combine harvester.

Description

technical field [0001] The invention relates to a transmission device, which has a transmission housing, a transmission chamber surrounded by the transmission housing, a first shaft supported in a box, and a center of gravity of its section in the first shaft that is eccentric to The cavity provided by the axis of rotation and a passage provided in the first shaft connect the transmission chamber with the cavity of the shaft. Background technique [0002] Transmissions known from the prior art have transmission gears arranged at an angle to one another, which have transmission shafts arranged staggered relative to one another. A transmission with staggered transmission shafts is also relatively compact and allows eccentric operation. Drives with eccentric motion are used, for example, in agriculture to drive cutting devices on harvesting attachments of combine harvesters. [0003] A transmission of this type is known, for example, from US 6,273,214 B1. A transmission is d...
