Bevel helical gearbox

The bevel helical gearbox has the following functions: 1. Accelerated deceleration, which is often said of gearshift gearbox. 2. Change the direction of the transmission. For example, we can pass the force perpendicular to the other axis with two fan-shaped gears. Change the torque. In the same power condition, the faster the speed of the gears, the smaller the torque of the shaft, the larger the torque. 4. Clutch function: we can achieve the purpose of separating the engine from the load by separating two original meshing gears. Such as brake clutch, etc. 5. Distribution of power. For example, we can use an engine to drive multiple axes from the main shaft of the gearbox to achieve the function of one engine driving multiple loads.

Cycloidal gearbox

Cycloidal gearbox
1.Big transmission ratio:for single-stage,ratio is 1/11-1/87,double-stage,ratio is 1/121-1/5133,three-stage ratio can be 1/2057-1/446571.We can adopt more-stage compound according to requirement.

2.High driving efficiency:the driving efficiency can reach above 90% due to adopting rolling engagement in falling-in part.

3.Small volume,light weight:speed reducers has compacted structure,small volume and light weight due to adopting the principle of planet driving so that the input shaft and output shaft in the same axis.Moreover,they will integrated with the motor.

4.Few troubles,long life:speed reducers has good resistance to abrasion because the main driving engaging parts are made of bearing steel and applying rolling friction.

5.Stable running:for most driving procedure,we adopt multi-teeth falling-in,So the running will be stable a little noise.

6.Convenient dimmounting,easy maintenance:due to reasonable structure and design.

7.Speed reducers also are of the characteristics such as strong overloading ,anti-compact,small inertial moment,which are suitable for frequently start and double-side rotation.

Composition

Cycloidal gear reducer on the input shaft is equipped with a displacement of 180 ° double eccentric sleeve, turn on the eccentric sleeve is equipped with two known as the arm of roller bearing, the formation of H, two cycloid gear center hole is the eccentric sleeve on the turning arm bearing raceway, and by a group of cycloid gear and pin gear mesh circular permutation needle, to form tooth difference, for the internal meshing gear reducer is institutions (in order to reduce friction, in small ratio of speed reducer, the needle with needle teeth on the gear set).

dynamic oil gearbox

Manual transmission oil: the manual transmission oil is usually used as the gear oil, only to lubricate it. The American petroleum institute has divided the vehicle gear oil into the gl-1, gl-2, gl-3, gl-4, gl-5, gl-6 classes. Among them, the heavy - heavy GL- 1, gl-2, gl-3 have been eliminated in the market, and the current use of family cars is generally gl-4, gl-5 (GL -6 is used by passenger cars). In terms of product features, the most intuitive is manual transmission oil is bigger than the viscosity of the automatic transmission fluid, the replacement cycle shorter than automatic transmission oil are also generally, most of the family car in the 4-60000 - km to replace manual transmission oil.
Dynamic oil gearbox: automatic transmission oil is special, it has two functions, except with planetary gears lubrication, cooling, what is more important as transmission power, so it's not as "thick" as manual transmission oil viscosity. And its main function is to have hydraulic transmission, so the liquidity is very good, the anti-bubble capability is also more stringent than the manual transmission oil.
