Product details:

The applicability of the ZLL type brake roller pin coupler is applicable to the transmission shafting of the two coaxial lines, with some compensation for the relative deviation of the two axes and the general damping performance.

Working environment temperature is 20 ~ + 70 ℃. Do not apply to the high requirement of the damping effect and on the part of the need to control noise.

The basic parameters and main dimensions of the couplings of the ZLL type brake roller pin couplings are:

Nominal torque Tn: 250N. M

Allowable speed n: 4000r/min

Shaft diameter d: 16, 18, 19, 20, 22, 24, 25, 28, 30, 32mm

Axis length Y: 42, 52, 62, 82, J1 type: 30, 38, 44, 60mm

Brake wheel D0:160mm

Outer diameter D: 102mm

ZLL type belt wheel elastic dowel pin shaft coupling is the use of a number of non-metallic materials of the dowel pin, placed in two and a half coupling between inner surface and outer ring the involution of the hole, achieved by column pin transfer torque half coupling, the coupling has the following features:

(1) the transmission torque is large, and in the same torque, most of the rotating diameters are smaller than the tooth coupling, small in size and light in quality, which can be partially replaced by the dental coupling.

(2) compared with the gear type coupling, the elastic cylindrical pin gear coupling is simple in structure, with less components and more convenient manufacturing, and no gear processing machine.

(3) the flexible cylindrical pin gear shaft is easy to maintain and has a long life, so it can replace the nylon pin.

(4) the nylon pin of the elastic cylindrical pin gear spindle is self-run material, which does not need to be lubricated and not only saves the lubricating oil, but also purifies the working environment.

(5) the vibration can be poor and the noise is larger.
