Bevel helical gearboxes
Bevel helical gearboxes
The bevel helical gearboxes are designed for demanding industrial applications, offering versatility, easy installation, adaptability, and cost-effectiveness. They are suitable for general machinery, special purpose machines, lifting gear, crane installations, rolling mills, cable installations, conveyor drives, and stranding machinery.
The gearboxes feature a two-stage design with a bevel gearset for input and a helical gearset for output. Constructed from high-quality grey cast iron, they ensure durability and high efficiency. The modular design allows for various modifications.
The first stage uses Klingelnberg palloid-spiral gearing, allowing high torque transmission. The gears are made from alloy steel, hardened, and lapped for quiet operation, reduced backlash, and good efficiency.
Gearboxes are available with different ratios and designs, including solid shaft, hollow shaft, and flange options. Types include KS, KSH, KSHF, MKS, MKSH, and MKSHF.
The housing is made from cast iron or aluminum, with options for stainless steel and galvanic coating. Shafts are made from C45 or 42 Cr Mo 4+QT steel, with options for stainless steel or chromium coating. Bevel and helical gears are optimized for low noise and high torque, made from 16 Mn Cr 5 or 17 Cr Ni Mo 6 steel.
The input and output shaft directions are interdependent, with sides identified by letters A to F. Bevel gears are positioned on sides C and B, with side C as the input. Rotation directions are defined as clockwise or counterclockwise.
Lubrication options include mineral and synthetic oils, with special oils for food processing and extreme temperatures. The gearboxes are designed for easy maintenance and long bearing life.
The document provides detailed specifications for gear ratios ranging from 6.0 to 48.0, including specific configurations with hypoid gearsets for higher ratios. It lists various types such as KS, KSH, KSHF, MKS, MKSH, MKSF, and MKSHF, and notes that all mentioned ratios are mathematically exact, with other ratios available upon request.
Backlash is measured at 2% of the nominal output torque. Two quality standards are offered: Standard 1 is free, while Standard 2, available for sizes 1 to 16, incurs an additional cost. Certificates for backlash and runout error can be provided.
The efficiency of the gearbox is dependent on its nominal power. The document provides a table showing efficiency values for different gear sizes and ratios.
When calculating the maximum required input power, factors such as shock factor (c1) and ambient temperature (c2) must be considered. The document provides formulas and tables to calculate input power and select the appropriate gearbox size based on these conditions.
Gearboxes are supplied with oil filling, and for sizes 8 to 128, breather plugs must be fitted. The first oil change is required after 500 operating hours, with subsequent changes every 3000 hours. Different oil grades are recommended based on the gear ratio, with specific oils listed for ratios 6 to 28.8 and 33.6 to 48.
The nominal output torque can be temporarily overloaded by a factor of 1.8, with emergency stop output torque permissible for up to 1000 stops.
The document provides detailed specifications for motor and gearbox components, including dimensions and mounting instructions. Key parameters include motor shaft diameter, centring diameter, pitch circle diameter, and motor shaft length. Various sizes and configurations are outlined, such as square and round flanges, with specific measurements for each.
Instructions for motor mounting are provided for different gearbox sizes (8-32, 64-128, and 1-4). The document emphasizes the importance of using a keyway for certain sizes and provides step-by-step assembly instructions, including torque specifications for tightening screws.
The document recommends using motors with reduced shaft tolerance and concentricity according to DIN 42955 R standards for optimal performance. It also highlights the necessity of ensuring that motor shafts and clamping sleeves are free from dirt and grease before assembly.
The tables provide possible motor shaft and flange dimensions, along with the maximum torque transmission capabilities of shrink disk couplings. Specific screw sizes and quality standards are also listed.
Attention is drawn to the requirement of using motor shafts with keyways for gearbox sizes 8-32 to ensure torque transfer during emergency stops. The document also specifies that certain designs are not available for gearbox size 128.
The document provides detailed specifications for various types of gearboxes, specifically focusing on the inertia types KS, KSH, MKS, and MKSH. It includes data on size, translation ratios, and mass moments of inertia, with values given in kgcm².
Instructions are provided for the operation of gearboxes, emphasizing the importance of ensuring the oil pump is running before starting the gearbox. The document also outlines the electrical connection data for the oil pump, including power, voltage, speed, and protection type.
The document specifies permissible radial and axial loads for input and output shafts at various speeds and gearbox sizes. It also highlights the thermal power limits of bevel helical gearboxes under specific conditions, such as maximum input speed, ambient temperature, and operation mode.
The tables provide extensive data on permissible loads, inertia values, and thermal ratings across different gearbox sizes and speeds. Key data includes:
- Permissible radial and axial loads for input and output shafts at various speeds and gearbox sizes.
- Mass moments of inertia for different gearbox types and sizes.
- Thermal power limits for bevel helical gearboxes under specified conditions.
The document includes contact information for Lenze distribution partners across various regions, including Germany, Australia, Austria, Belgium, Brazil, China, Czech Republic, Denmark, Finland, France, Hungary, India, Iran, Israel, Italy, Korea, Lithuania, Latvia, Estonia, and Mexico.
