China Professional DC Motor High Torque 12V DC Gear Motor Encoder Robot 37mm Gearbox synchromesh gearbox

Product Description

Product Description

High Power version with 5A stall current:5A 
With 64CPR encoder or not  64CPR ;
With back shaft or not.
With metal brush or carbon brush.
This 37mm diameter gearbox motor, the first stage by the spur tooth, helical pinion options, if there is a gear operation requires a small clearance, generally choose helical gear.
At present, there are 2 kinds of voltage, 12V and 24V, and the parameters of the motor are the same.
We have a variety of gearbox ratios, from 10:1 to 810:1.
The same gearbox can also be matched with different motors such as 3530,540,545,555, etc., to form a wide range of output speeds and torques.
This motor can be equipped with a 16PPR (64CPR) magnetic encoder, so that it has the same function as a servo motor, cost-effective is very high, used in a variety of intelligent control products, such as robots, 3D printers and so on.

Can I Use Synthetic Oil in My Gearbox?

Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:

  • Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
  • Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
  • Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
  • Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
  • Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
  • Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
  • Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.

However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.
