Rotary shafts
Rotary shafts are mainly used as rotative guides. They are pivot mounted axles and are used to support one or more moving components, such as joints, ball bearings, wheels, rollers, gears or timing pulleys. Primarily, they derive bending moments and forces and are predominantly subjected to bending. However, rotary shafts are not firmly connected to a machine frame, but to the components stored on it. Rotary shafts are therefore subjected to the same rotational and circular movements as the components to which they are connected.
MISUMI manufactures rotationally symmetrical make-to-order (MTO) components in accordance with the respective customer-specific requirements: In the online shop, rotary shafts can be configured precisely and with regard to various specifications, which means that they can be tailored to all requirements. This eliminates the need for the customer to create individual drawings and the process for manufacturing the required shaft, including order tracking, production, heat treatment and surface treatment. Designers can choose from various geometries, end shapes and different materials, for example. In addition, various surface finishes (untreated, bronzed and nickel-plated) are available and the shaft diameter can be freely varied in the range of 2 to 50 mm. No other manufacturer can configure rotary shafts in this way in small parts.
Configuration options in our online shop:
- Various end forms: Straight, internal thread, external thread, flat surface, ring groove, hexagon socket
- Selectable materials: Cast iron, cast aluminum, stainless steel and steel
- Various surface treatments: Untreated, bronzed or nickel plated
- Various versions: Solid, offset solid on one side, offset solid on both sides, offset solid on both sides, hollow
- Freely selectable shaft diameter: From 2 to 50 mm
Sample application workpiece rotation and transfer mechanism
In this application, a stepper motor with gearbox transmits the rotational movement of the motor to a synchronous belt pulley by means of a coupling and a rotary shaft, also called a drive shaft. The ratio of the synchronous drive is 2:1. This allows the swivel arm to rotate 90° and the gripper to rotate 180°.
