Product details:

ZLZ type elastic dowel pin 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 ZLZ type elastic cylindrical pin gear coupling has the following characteristics:

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

(2) compared with the tooth type couplings, the structure is simple, with fewer components and more convenient manufacturing

(3) the maintenance is convenient, the life is longer, remove the plate and replace the nylon pin.

(4) nylon pin is self-run material, not lubrication, not only saves the lubricating oil, but also purifies the working environment.

(5) the vibration can be poor and noisy.

ZLZ type coupling type elastic dowel pin has a certain compensation performance of the two axes relative offset, suitable for medium and high power drive, does not apply to have a certain request for vibration damping and noise must be kept under strict control of the work.

ZLZ type elastic cylindrical pin gear coupler nylon pin is self-run material, not need lubrication, not only saves lubricating oil, but also purifies the working environment. Applicable occasions: elastic dowel pin type coupling with certain compensation performance of the two axes relative offset, suitable for medium and high power drive, does not apply to have a certain request for vibration damping and noise must be kept under strict control of the work. Components elastic dowel pin nylon material selection in general, there are two axis offset trace compensation ability, flexible work under shear, work reliability is poor and is only applicable to medium speed transmission shafting with low requirements, the operation condition of the high reliability requirement does not apply to work.

ZLZ type elastic dowel pin 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 of the involution in the hole, achieved by column pin transfer torque half coupling. ZLZ meet intermediate elastic dowel pin coupling analysis of the five big assembly steps are as follows: the individual components of the coupling processing, we're going to be assembled. The main parts are machined two and half couplings and outer rings, several nylon rods, baffles and screws.

1. Set the outer ring on the semi-coupler and the suitable baffle to be mounted on the flange of the semi-coupling, and fasten the outer ring and the semi-coupler with screws.

2. Fill the hole between the outer ring and the half coupling rod.

3. Put the other half coupling in the outer ring.

4. Load the other nylon rods into the outer ring and the hole of the half coupling.

5. The other baffle is fixed with the outer ring of the coupling.

The basic parameters and dimensions of the flexible cylindrical pin type couplings are mainly aimed at the diameter of the shaft hole 12mm. There is no specific reference for the basic parameters of the coupling and the main dimensions of the coupling. In actual production, the shaft hole diameter is less than 12mm, which requires us to design the non-object coupling. Between the motor and the output shaft coupling with small elastic dowel pin connection, the original structure sometimes can lead to the limitation of load transfer of the motor, we analyzed the specific reasons, and the failure of the motor coupling half coupling structure redesign.

Improve the structure and principle of improvement before the motor and coupling connection is: motor with half coupling 4 parts is 6 mm, length is 32 mm, shaft keyway, unable to realize linkage transmission torque, according to the requirements of the motor assembly, between the motor and coupling half hole using transition fit, torque mainly depend on the half coupling with two set of M5 screw transmission, in use process, the structure of the following deficiencies:

(1) between the motor shaft and the compact screw, the contact surface is very small and the transmission torque is very limited.

(2) threaded connection with locking function, after several disassembling and long time operation, can cause the relative coupling shaft and motor shaft rotation and axial moving, the device will not work.

Structure and working principle of the improved according to the above situation, we improved the half coupling structure, will first half coupling 4 whole processed into finished products, and then thread cutter edge of the location of the diameter of axle center this is divided into two parts, the main pieces of accessories for locking block for coupling half body, improve the body away from the motor end of the second half coupling, inner hole is complete, ensure the motor shaft alignment requirements, motor shaft, the main body and locking block through the socket head cap screw and spring washer join together, because the locking block coupling half cut after processing the finished product, so will not affect the body of the half coupling and motor after assembly alignment requirements. Application of this structure, the torque transmission parts with the original line and into the surface and surface contact, contact along the axial length increases, thus increasing the motor and coupling of contact area, also can transfer torque, socket head cap screw and lock spring washer between blocks have locking effect, the coupling high speed rotates, socket head cap screw would not loosen. Application of this structure in the form of coupling, through actual use, can be very good, to realize the torque transfer in other small coupling structure, the application of this structure, also can get a lot of good effect.
