This system makes shaft reaction fce due to mounting misalignment extremely small. There is also a damping effect from sliding at the friction surface between the pin and dry metal.

4 Precautions f Handling (1) are designed f use within an operating temperature range of -30 to 100. couplings are water and oil resistant, but should not be used in extreme atmospheres. (2) Never tighten the clamping bolt (hex-socket-head bolt) pri to inserting the shaft into the coupling. (3) Remove any rust, dust, oil the like from the inner diameter surfaces of the shaft and coupling. Be particularly careful to degrease otherwise process to fully remove any grease, oil, the like that is molybdenum disulfide based contains extremepressure additives that causes fundamental changes in coefficients of friction. (4) Mount couplings after checking, by the following st of method, that differences between coupling centers during operation are within the misalignment shown in the specifications table. CPU models allow angular deflection of up to 4 at this time, but it should be kept within 1.5 if it is imptant that the coupling be isokinetic. The angular velocity ratio at an angular deflection of 1.5 is ε Items Checked f Design Purposes Parallel misalignment Angular deflection tanθ= B1-B2 D (5) couplings are not structurally able to absb axial displacement, so do not place tensile compressive loads on them during use. (6) The length of insertion of the shaft into the coupling should be the dimension L1 on the dimensions table. The shaft cannot go all the way through. (7) Tighten clamping bolts (hex-socket-head bolt) to the tightening tques shown using a calibrated tque wrench.

Do not apply oil, grease, fixatives (adhesives) the like to the clamping bolt (hex-socket-head bolt). D B1 B2 θ Selection Procedures (1) Find the tque, Ta, applied to the coupling using the output capacity, P, of the driver and the usage rotation speed, n. Ta = 9550 (2) Determine the service fact K from the usage and operating conditions, and find the crected tque, Td, applied to the coupling. Service fact based on load property: K1 Load properties Constant P [kw] n[min 1 ] Td = Ta K1 K2 K3 K4 K5 Vibrations: Small Vibrations: Medium Vibrations: Large K Service fact based on amount of parallel misalignment: K2 Parallel misalignment K Service fact based on amount of angular deflection: K3 Amount of angular deflection [ ] K Service fact based on operating temperature: K4 Atmospheric temperature [ ] K Service fact based on rotation speed: K5 rotation speed K (3) Select the size so that the nominal tque (CPE models) rated tque (CPU models) Tn is at least equal to the crected tque, Td. Tn Td (4) Select a size that results in a maximum tque (CPE models) rated tque (CPU models) Tm that is at least equal to the peak tque, Ts, generated by the driver, follower both. Maximum tque (CPE models) refers to the maximum amount of tque that can be applied f a set amount of time, considering eight hours of operation per day and up to around ten instances. Tm Ts K4 (5) When the required shaft diameter exceeds the maximum be diameter of the selected size, select a suitable coupling.
