China high quality Speed Increasing Gear Box of 135m Finishing Mill with Best Sales

Product Description

Composition of speed increasing gearbox

Spare parts of speed increasing gearbox case(lower case, middle case and cover), support base, big gear, transmission axis, bevel wheel and lubrication system.

2,Technical characteristics

Box is melt with thick steel with great quality to reach the intensity that the case required. Case should take stress aging treatment before the produce to reach the stability that required. High precision lathe machining is used for the assembly of cases to insure the locating accuracy of each bearing holes and related joint surface. 
Big gears and gear shaft used carbon alloy steel forging blank, after roughing, workpiece need to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing .Fine grind of tooth surface to insure the high accuracy, after finishing the production of gear, the balance test is needed, the trail speed is 1500r/min and the balance precision grade is G2.5. the trail speed of bevel wheel is 3500r/min, the balance precision grade is G1, in so to ensure the rotary precision of the gears.
Transmission shaft use the alloy steel forging blank, transmission shaft takes quenched to make sure the intensity and durableness. After the semi- finishing, transmission need to grind to guarantee the accuracy of every workpiece.
When the assemble finished, the no-loading test should be keep 2-4hours, the speed is 1100r/min, the temperature of shaft should not exceed 40ºC,the work of gear should be smooth, no hitting noise and concussion, every joint surface should not have oil spill phenomenon.

Steps to Replace a Faulty Gearbox in an Automobile

Replacing a faulty gearbox in an automobile is a complex task that requires proper tools, skills, and safety precautions. Here are the general steps involved in the process:

  1. Prepare the Vehicle: Park the vehicle on a flat surface and engage the parking brake. Disconnect the battery to ensure safety during the procedure.
  2. Drain Fluids: Drain the transmission fluid from the old gearbox into a suitable container.
  3. Disconnect Components: Remove any components obstructing access to the gearbox, such as the driveshaft, exhaust system, and linkage.
  4. Suspend the Engine: If necessary, use an engine hoist or support to suspend the engine safely.
  5. Support the Gearbox: Use a transmission jack to support the weight of the gearbox.
  6. Remove Gearbox: Detach the gearbox from the engine by removing bolts and disconnecting the clutch or torque converter.
  7. Install New Gearbox: Position the new gearbox onto the engine and secure it in place with bolts.
  8. Reconnect Components: Reattach the driveshaft, exhaust system, and linkage that were disconnected earlier.
  9. Refill Fluids: Fill the new gearbox with the appropriate transmission fluid according to the manufacturer’s specifications.
  10. Lower Engine: Carefully lower the engine back into its original position if it was suspended.
  11. Test and Adjust: Start the vehicle and test the new gearbox for proper operation. Check for any leaks, unusual noises, or gear shifting issues.
  12. Final Check: Double-check all connections and ensure that all components are properly secured.
  13. Dispose of Old Fluid: Dispose of the old transmission fluid safely and responsibly.
  14. Dispose of Old Gearbox: Properly dispose of the old gearbox according to local regulations.

It’s important to note that gearbox replacement can vary significantly depending on the vehicle’s make and model. It’s recommended to consult the vehicle’s service manual or seek professional assistance if you’re not experienced in automotive repair.
