Product Description
Mechanical Transmission Gearbox- QTJF15/20/25/30 Series
Suitable for 1.5tons – 3 tons diesel forklift.
Brand:TCM,HELI,DOOSAN,HANGCHA,TAILIF…..
Characteristics:
1)Driving axle integrated transmission can make the power plant including engine, transmission and reducer float on the vehicle body.
2)Split-type layout connected by damping block and universal coupling leads to low vehicle vibration and eases driver’s fatigue.
3)Sliding (Inertial lock-ring) synchronizer makes the shifting more flexible and has less impact.
4)The transmission has good bearing capacity, high transmission efficiency and stable operation.
5)Housing made of alloy cast iron has a beautiful appearance .
6)Application of evanescent mode and coated- sand solves the problem of raw material defect.

How to Choose the Right Gearbox for Your Machinery
Selecting the appropriate gearbox for your machinery involves careful consideration of several key factors. Here’s a step-by-step guide to help you make the right choice:
- Identify Application Requirements: Understand the specific requirements of your machinery, including torque, speed, load, direction of rotation, and duty cycle.
- Choose Gear Type: Determine the type of gears that best suit your needs, such as spur, helical, bevel, planetary, or others, based on factors like efficiency, noise level, and space constraints.
- Calculate Gear Ratio: Calculate the required gear ratio to achieve the desired output speed and torque. Consider factors like input and output shaft speeds.
- Select Gear Material: Choose appropriate gear materials based on factors like durability, wear resistance, and corrosion resistance. Common materials include steel, cast iron, and various alloys.
- Consider Efficiency: Evaluate the gearbox’s efficiency and select one that meets your energy efficiency requirements.
- Account for Load Conditions: Analyze the load conditions, such as constant or intermittent loads, shock loads, and starting and stopping frequencies.
- Check Lubrication Requirements: Consider the lubrication needs of the gearbox and ensure proper lubrication for smooth operation and longevity.
- Factor in Space Constraints: Consider the available space for installing the gearbox and choose a size that fits within your machinery.
- Assess Environmental Conditions: Evaluate the operating environment, including temperature, humidity, and exposure to dust or corrosive substances.
- Review Mounting Options: Determine the mounting options that work best for your machinery, such as foot-mounted, flange-mounted, or shaft-mounted gearboxes.
- Consult with Experts: Seek advice from gearbox manufacturers or engineers to ensure you make an informed decision.
Choosing the right gearbox is crucial for achieving optimal machinery performance, longevity, and reliability.
