Automatically cut off the working intensity of the tooth rubbing machine

Automatic cutting and rubbing machineThe coupling sizes of the initially selected coupling, the shaft hole diameter d and the shaft hole length L should meet the requirements of the diameter of the spindle and driven shaft end. Otherwise, the coupling diameter must be adjusted according to the shaft diameter d. The coupling size, that is, the largest radial and axial dimensions, must be within the allowable installation space of the machine. Due to factors such as manufacturing errors, assembly errors, installation errors, shaft load and deformation, base deformation, bearing wear, temperature changes, and relative movement between components, the two axes of the coupling of the polyurethane equipment are opposite and displaced.

Automatic cutting and rubbing machineUnder normal circumstances, the relative displacement of the 2 axis of the winder is difficult to avoid. However, under different working conditions, the directions of the balanced displacement driven by the axial and radial angle directions and displacement amounts are different.

Automatic cutting and rubbing machineThe sealing conditions must be checked frequently, injected grease or grease, maintain a lot of work, increase auxiliary working time, and reduce effective working time of standard parts and affect production efficiency. The traditional system load category is the basic basis for selecting coupling types. The following is the relationship between the coupling and working load of the lower coiler.

If a collision occurs, vibration and winding machine workload changes, a flexible coupling (i.e., flexible coupling) with elastic elements should be selected to buffer, dampen and compensate for the misalignment of the shaft, thereby improving the performance system of the driver. During frequent start-up, forward\/reverse and braking, the torque of the paper rolling machine is several times that of normal steady-state operation. This is an overload operation, and the service life of the coupled elastic elements will inevitably be shortened. The coupling can only allow for short-term overload. Generally, short-term overload must not exceed 2 to 3 times the rated torque.
