The flexible pin gear coupling: 1: BL stick pin coupling: BL-type stick pin coupling and nylon pin coupling belongs to the elastic non-metallic flexible element couplings for reversing change , frequent start of the two-axis coupled. Its simple structure, easy maintenance, hammer crusher. Nylon material for the elastic element, longer life expectancy, but the two shaft concentricity requirements, or nylon rod pin or dowel pin circular vibrating screen easy to break. Its operating temperature should not exceed 70 ℃ Zhengzhou beneficiation equipment. Nylon rod pin coupling is used for heavy machinery, cement plant the shaft kiln discharge driveline Note the application of more cone crusher. Transmit motion and power of the stick pin coupling with a swivel without disengagement device. In addition, the coupling compensation axis relative displacement, buffering and damping, and security features. 2: ZL elastic dowel pin gear coupling: flexible pin gear coupling is the use of a number of non-metallic materials Pin, placed between the coupling halves with the surface of the outer ring on the engagement hole Pin transmit torque to achieve the two coupling halves join the flexible pin gear coupling has the following characteristics: (1) transfer torque same diameter rotary torque most than tooth-associated axis is small, small size, light weight, and can partially replace the gear coupling. (2) gear coupling, flexible pin gear coupling structure composed of fewer parts, manufacturing is more convenient, without gear cutting machines. (3) easy maintenance, longer life expectancy, remove the baffle can be replaced nylon dowel pin. (4) nylon dowel pin for a self-lubricating material, without lubrication, not only saves lubricant, and clean work environment. (5) damping the kinetic energy differential noise. The flexible pin gear coupling must compensate two axis relative offset performance, suitable for medium and large power transmission, does not apply to certain requirements and noise damping have tight control on working parts 3: ZLL type - gear coupling with brake wheel flexible pin: ZLL type - flexible pin brake wheel gear coupling easy maintenance, longer life expectancy, remove the baffle can be replaced nylon dowel pin. The nylon pegs for a self-lubricating material, without lubrication, not only saves lubricant, and clean work environment. 4: ● ZLD conical shaft hole flexible pin gear coupling is the use of a number of non-metallic material Pin, placed the involution hole between the two coupling halves outer ring inner surface, by dowel pin to transmit torque to the two coupling halves join the coupling has the following characteristics: ● (1) pass torque, the same torque rotary diameter of the majority than the small gear coupling, small size, The quality of light, can partially replace the gear coupling. ● (2) gear coupling, simple structure, composed of fewer parts, without manufacturing gear cutting machines. ● (3) easy maintenance, longer life expectancy, remove the baffle can be replaced nylon dowel pin. ● (4) nylon dowel pin for a self-lubricating material, without lubrication, not only saves lubricant, and clean work environment. ● (5) kinetic energy differential damping noise. ZLD conical shaft hole flexible pin gear coupling must compensate for the two axes relative offset performance, suitable for medium and large power transmission, does not apply to certain requirements and noise damping need to exercise strict control work site. : ZLZ connected intermediate shaft flexible pin gear coupling characteristics: (1) transfer torque, the same torque rotary diameter of the majority than the small gear coupling, small size, light weight, can be partial replacement of the gear coupling. (2) gear coupling, flexible pin gear coupling structure composed of fewer parts, manufacturing is more convenient, without gear cutting machines. (3) easy maintenance, longer life expectancy, remove the baffle can be replaced nylon dowel pin. (4) flexible pin the gear couplings nylon pin self-lubricating material, without lubrication, not only saves lubricant, and clean work environment. (5) flexible pin gear couplings damping kinetic energy difference, noisy. The applicable occasions of a flexible pin connected to the intermediate shaft teeth ZLZ coupling: flexible pin gear coupling must compensate two axis relative offset performance, suitable for medium and large power transmission, not apply damping There are certain requirements and noise needs to be kept in strict control of the work site.
