Embodiment Construction

[0046] The examples described in detail below are preferred embodiments of the invention.

[0047] figure 1 The combined drive for rotary and reciprocating linear movements shown in can be used, for example, in machine tools or robots. It has a rotary motor 1 and a linear motor 2 . Both drive the working axis 3 .

[0048] The combined drive has an output, via which the active power is supplied. exist figure 1 In the embodiment of , the output device is on the left, and the corresponding active power is provided by the working shaft 3 . Accordingly, the working shaft 3 has an output side 4 and a drive side 5 .

[0049] The rotary motor 1 (electric motor for performing a rotary movement or rotary motor) is located closer to the output of the combined drive than the linear motor 2 . However, this also means that the rotary motor 1 is located closer to the output side 4 of the working shaft 3 than the linear motor 2 .

[0050] The working shaft 3 here passes completely thro...

Abstract

Motive power of a combined driving device or a linear motor should be improved, and accordingly a combined driving device for performing rotational motion and reciprocating linear motion is provided that possesses a rotary motor (1) and a linear motor (2) and an operating shaft (3). The operating shaft (3) can be rotated by the rotary motor (1) to perform rotational motion and can perform linear motion by the linear motor (2); the operating shaft (3) possesses an output side (4). The rotary motor (1) is more closely arranged on the output side (4) of the operating shaft (3) than the linear motor (2). Accordingly the operating shaft (3) can be designed to be shorter. The measure of improving motive power is to reduce rotor quality of the linear motor (2).

Description

technical field [0001] The invention relates to a combined drive device for rotary motion and reciprocating linear motion, which has a rotary motor, a linear motor and a working shaft that can be transferred from the rotary motor to rotary motion and from the linear motor to linear motion. motion, and the working shaft has an output side. Background technique [0002] Combined drives are used for drive tasks that require rotary and linear movements. It is advantageous here that these movements can be freely adjusted independently of one another in terms of angle and path. Furthermore, it is often required that these movements be performed with high dynamics. [0003] To date, comparatively inflexible drives with steering gears have mostly been used for the realization of combined drives. For example, the dynamics of the combined drive can be significantly increased by targeted decoupling of the inertia for linear and rotational movements. In particular, this results in a...
