2. Product Introduction
This product portfolio covers full-range core supporting parts for JC135 transmission systems and 330H clutch devices, including core crank assemblies, compensating beams, tie rods and connecting rod assemblies that form the main transmission structure. It is equipped with 22240C self-aligning bearings, multi-specification gaskets, copper washers and spring components for structural buffering and positioning. The product line also includes NPT standard pipe elbows, C-type rubber hoses, grease nipples, sprockets, shaft assemblies and complete fastener sets, as well as professional auxiliary parts such as brake band assemblies, crank arms and water inlet pipes. All components adopt precision forging and finishing processes, with unified tolerance calibration and high interchangeability, supporting direct on-site replacement without secondary machining for matched equipment.
3. Core Functional Description
The assembly undertakes mechanical power transmission, low-temperature clutch power switching, structural buffering positioning, pipeline connection and braking execution for heavy industrial equipment. Left and right crank assemblies cooperate with connecting rods and compensating beams to realize stable torque transmission of the main unit. The 330H low-temperature airbag thrust disc clutch ensures flexible power switching and avoids transmission stall in low-temperature working environments. Frame and drum bearing boxes reduce rotational friction of moving parts and support long-term high-load operation. Standard pipe fittings and rubber hoses ensure smooth medium transmission and tight connection sealing. Brake handle assemblies and brake bands provide reliable friction braking performance, while adjusting gaskets and lever structures realize precise system gap calibration and operation debugging.
4. Structural Characteristics
Adopting optimized modular integrated structure, this component assembly boasts outstanding structural coordination and environmental adaptability. The matched 22240C self-aligning bearing design compensates for installation deviation and reduces eccentric wear of rotating parts. Multi-specification gaskets and copper washers form multi-layer sealing protection to eliminate joint leakage risks. The low-temperature optimized 330H clutch structure maintains stable mechanical flexibility in extreme low-temperature environments, different from ordinary clutch parts that are prone to hardening failure. Sprocket and shaft assembly sets adopt high-precision tooth profile and shaft diameter matching to ensure synchronous transmission accuracy. Multi-type spring and spring seat components effectively buffer equipment vibration and extend the service life of structural parts.
5. Applicable Working Conditions
This series of components adapts to complex and harsh heavy-duty industrial scenarios, primarily including onshore oilfield hoisting and production equipment, mining heavy transmission machinery, industrial low-temperature operating workshops and fixed heavy mechanical operating platforms. It stably operates in ambient temperatures ranging from -35℃ to 70℃, resisting low-temperature embrittlement, field dust erosion, mechanical vibration and high-torque impact loads. It fully meets the working requirements of long-duration continuous operation and frequent start-stop switching of JC135 series transmission equipment and 330H low-temperature clutch devices.
6. Maintenance Guidelines & Engineer Practical Tips
Senior field mechanical engineers have summarized targeted maintenance specifications and failure avoidance tips for this assembly. Inspect the tightness of crank arm and connecting rod assembly connections every 30 days to prevent transmission gap deviation. Check the flexibility of 330H clutch airbag action and bearing operation status every 60 days, replacing aging deformed gaskets and rubber hoses in a timely manner. Inject lubricating grease through M10x1 grease nipples regularly to reduce bearing and shaft part wear. Calibrate the gap of brake bands and adjusting gaskets every 90 days. Standardized cyclic maintenance can extend the stable operation cycle of the entire transmission and braking system by 8800 hours compared with irregular maintenance modes.
