The assembly of the head pulley for an elevator involves assembling components such as the sprocket, main shaft, bearings/bearing housings, expansion sleeves (or keys), seals, and locating retaining rings into a complete drive wheel assembly in accordance with process requirements. This assembly serves as the core power-transmission unit for bucket elevators and plate-chain conveyors, directly affecting operational smoothness, sealing performance, and service life.
Custom-made plate-type sprocket for 40B chain
Medium-carbon steel and alloy steel, with case-hardened tooth surfaces for wear resistance and impact resistance.
Flaw Detection of Cement Head Conveyor Sprocket
Flaw detection of cement industry head drive sprockets is a nondestructive testing (NDT) procedure specifically designed for heavy-duty, actively driven sprockets at the heads of bucket elevators, plate-chain conveyors, and clinker conveyors in the cement industry. It is used to identify potential defects such as cracks, shrinkage cavities, inclusions, and heat-treatment-related flaws that are prone to occur under conditions of heavy loading, impact, high dust levels, and prolonged continuous operation. By doing so, it helps prevent tooth breakage, spalling, equipment downtime, and safety incidents, making it an essential step in factory acceptance inspections, major overhaul acceptance, and safety assessments of cement conveying equipment.
Non-standard sprockets refer to custom-designed sprockets whose tooth profile, structure, dimensions, and materials do not conform to national or industry standards. They are used to address operating conditions—such as space constraints, non-linear motion paths, heavy-load/high-speed applications, and corrosive environments—that cannot be met by standard sprockets.
The parking garage sprocket is the core transmission component of mechanical parking systems such as lift-and-shift and vertical-circulation systems. It drives the lifting and lateral movement of the vehicle-carrying platform, supports the weight of both the vehicles and the equipment, and is characterized by heavy-load capacity, low speed, and high safety.
The tail sprocket (also commonly referred to as the tail wheel, driven sprocket, or deflection sprocket) is a core driven component that is paired with the head drive sprocket and installed at the tail end of plate-chain conveyors, bucket elevators, clinker conveyors, and scraper conveyors in the cement industry. It is specifically designed for the harsh operating conditions of cement production, which involve high dust levels, heavy loads, continuous operation, and severe wear.
A duplex sprocket, also known as a double-row sprocket, is a coaxial, integral sprocket with two rows of teeth, used to drive a double-row chain or two parallel single-row chains.
Involute internal gear sprocket
Typically, a greater number of teeth is used to reduce the polygon effect.
Head and tail pulleys of the cement conveyor line
The head and tail pulleys for cement conveying lines are the core drive components of complete sets of plate-chain conveyors, bucket elevators, clinker conveyors, and scraper conveyors in the cement industry. Designed as a matched set—one driving and one idling—they are specifically engineered to withstand harsh operating conditions characterized by heavy loads, high dust levels, severe impact, and continuous 24-hour operation.
Typically, a greater number of teeth is used to reduce the polygon effect.
Typically, a greater number of teeth is used to reduce the polygon effect.
The head sprocket for cement conveying lines is the primary drive sprocket at the head of equipment such as plate-chain conveyors, bucket elevators, clinker conveyors, and chain feeders in cement production lines. It is a specialized core component designed for heavy-load operation, high-dust environments, severe impact, and continuous running, responsible for transmitting power and driving the conveyor chain—essentially serving as the “power heart” of the entire cement conveying system.
Typically, a greater number of teeth is used to reduce the polygon effect.
Typically, a greater number of teeth is used to reduce the polygon effect.
The glove machine sprocket is the core transmission component of the glove knitting, dipping, shaping, and packaging production line, used to drive, tension, and redirect the glove machine chain (such as 06B, 08A, and 12A), and is designed to meet the demanding requirements of high-speed, continuous, low-noise, and high-precision glove manufacturing.
