German VOSWINKEL coupling VOSWINKEL model VOSWINKEL price

VOSWINKEL coupling is a high-speed rotating body with few supports, so its dynamic balance is crucial. Generally, drive shafts undergo dynamic balance testing before leaving the factory and are adjusted on balancing machines. For front-engine, rear-wheel-drive vehicles, it is the shaft that transmits rotation from the transmission to the final drive; it can consist of several sections connected by universal joints.

VOSWINKEL coupling structure

It consists of two shaft hubs and a center slider. The center slider, acting as a torque-transmitting element, is usually made of engineering plastic; in special cases, other materials such as metal can be selected. The center slider is connected to the shaft hubs on both sides via slots distributed at 90° relative to each other, thereby achieving torque transmission. A slight pressure fit between the center slider and the shaft hubs ensures zero-backlash operation during equipment runtime. Over time, the slider may lose its backlash-free function due to wear, but the center slider is inexpensive and easy to replace, restoring original performance after replacement. Slider couplings are commonly used with standard motors and, in specific cases, to connect servo motors, correcting relative displacement through the sliding of the center slider. Since the half-couplings and the intermediate disc form a sliding pair and cannot rotate relative to each other, the angular velocity of the driving and driven shafts must be equal. However, when operating with relative displacement between the two shafts, the intermediate disc generates significant centrifugal force, increasing dynamic loads and wear. Therefore, care must be taken during selection to ensure the operating speed does not exceed the specified value. This type of coupling is generally used for speeds n<250r/min, where shaft stiffness is high and there are no severe impacts.

VOSWINKEL coupling features

The material for slider coupling parts can be 45 steel, with heat treatment required on working surfaces to increase hardness; for lower requirements, Q275 steel can be used without heat treatment. To reduce friction and wear, lubrication should be applied through the oil hole in the intermediate disc during use. Since the half-couplings and the intermediate disc form a sliding pair and cannot rotate relative to each other, the angular velocity of the driving and driven shafts must be equal.

Slider couplings are commonly used with standard motors and, in specific cases, to connect servo motors, correcting relative displacement through the sliding of the center slider. Since resistance to relative displacement comes from the friction between the slider and the shaft hubs, the bearing load does not increase with greater relative displacement. Slider couplings can eliminate additional loads between shafts during automatic motor control; the fixed body uses splines for sliding, while the inner and outer sleeves of the sliding body can slide relatively in the axial direction; this coupling integrates sliding and rotation; for the same rotational diameter, its shortest dimension is far smaller than that of a cross-axis coupling. It improves the uniformity of load distribution on the working surface and can transmit higher torque, though elasticity is slightly reduced.

VOSWINKEL coupling applications

Unlike other couplings, the slider coupling has no elastic elements that work like springs, so bearing loads do not increase with greater relative displacement between shafts. Regardless, this series of couplings offers good value for money, and the ability to choose sliders made of different materials is its greatest advantage. Juren Company can provide a variety of raw material options for center sliders to suit different applications based on specific customer requirements. Generally, one type of material is suitable for zero-backlash, high-torque rigidity, and high-torque conditions, while another type is suitable for low-precision positioning where zero-backlash is not required, but vibration absorption and noise reduction are needed. Non-metallic sliders also provide excellent electrical insulation and can serve as mechanical fuses. When the engineering plastic slider is damaged, torque transmission is completely terminated, thereby protecting valuable mechanical components. This design is suitable for large parallel relative displacements. The three-part design of the slider coupling limits its ability to compensate for axial deviations, meaning it cannot be used in push-pull applications. Additionally, since the center slider is floating, the motion of the two shafts must ensure that the slider does not disengage.
