Embodiment Construction

[0029] figure 1 and figure 2 A first embodiment of the balance shaft 10 of the present invention is shown. The balancing shaft 10 comprises two coupling parts 11 , 12 at opposite ends, whereby the balancing shaft 10 can be connected to a drive, in particular a sprocket drive.

[0030] In this embodiment the balancing shaft 10 also comprises four journals 13 , 14 , 15 , 16 for the mounting of radial bearings. The axis of rotation of the balancing shaft 10 is located at the center point of the journals 13 , 14 , 15 , 16 .

[0031] The journals 13 , 16 can each have a bearing inner ring on or at which a bearing (preferably a roller bearing) can be mounted in each case. In this connection it is preferred that the journals 13 , 16 are provided by bearing inner rings integrally formed on the main body, on which the bearings can then be slipped or clamped. For example, a bearing inner ring can be provided in which two correspondingly formed shoulders (not shown) which in combina...

Abstract

The present invention relates to a balance shaft (10; 10; 100) for balancing an inertial force and / or an moment of inertia of a piston reciprocating internal combustion engine, comprising: at least one elongated body; at least one of which is arranged on the elongated body (13, 14, 15, 16; 13 , 16; 102, 103) for the radial bearing mounting, wherein the axis of rotation of the balance shaft (10; 10 ; 100) (17, 18; 17, 18) are provided on the elongated body, and at least one unbalanced portion (17, 18; 17, 18) is provided on the elongated body, (10; 10;; 100); and on the at least one unbalanced portion (17, 18; 17, 18), the balance axis (10; 10; 100), the material is not substantially set in the area of the axis of rotation. The present invention also relates to a method of manufacturing such a balance shaft.

Description

technical field [0001] The invention relates to a balance shaft for balancing the inertial forces and / or moments of inertia of a piston reciprocating internal combustion engine and to a method for producing such a balance shaft. Background technique [0002] Many balancing shafts are known from the prior art. As a rule, the balancing shaft is produced from a rod-shaped shaft blank by means of hot forming and in particular by swaging. [0003] Such balancing shafts are usually provided in the form of a one-piece solid component, which thus indeed has a high degree of stability, but has a comparatively high component weight. As a result, the balancing shaft has a high mass fraction (Massenanteil), which does not provide a corresponding balancing force during operation, or which mass fraction sometimes has to be compensated by additional mass in order not to cause undesired disturbances during operation. balance. [0004] In contrast, in the development of modern balance sha...
