Bevel Gearbox Application Is Very Extensive
Gearboxes are widely used in wind turbines and are often used in wind turbines and are an important mechanical component. The main function of gearboxes is to transmit the power generated by wind wheels to power generation Machine and get the corresponding speed. Bevel Gearbox Usually the speed of the wind wheel is very low, Bevel Gearbox far less than the required speed of the generator power generation, must be achieved through the gearbox gear pair growth, it will also be called gearbox gearbox.
The gearbox has the following effects:
1, accelerated deceleration, is often said that the variable speed gear box.
2. To change the direction of the drive, Bevel Gearbox for example, we can use two fan gears to pass the force to another axis.
3, change the rotation torque. Under the same power conditions, the faster the speed of the gear, the axis of the smaller torque, and vice versa.
4, distribution of power. For example, we can use an engine, Bevel Gearbox through the gearbox spindle to drive a number of slave, so as to achieve an engine to drive multiple load function.
1. Gearbox with a common design, according to customer demand for the industry-specific gearbox.
2. To achieve parallel shaft, orthogonal shaft, vertical, Bevel Gearbox horizontal universal box, parts and components to reduce the specifications model increased.
3. The use of sound-absorbing box structure, Bevel Gearbox the larger the surface area of the box and the big fan, cylindrical gears and spiral bevel gears are using advanced grinding process, so that the machine's temperature rise, noise reduction, operational reliability is improved, Power increases.
4. Input method: motor connection flange, shaft input.
5. Output mode: solid shaft with flat key, hollow shaft with flat key, Bevel Gearbox hollow shaft with flattened plate connection, hollow shaft with spline connection, solid shaft with spline connection and solid shaft with flange connection.
6. Gear box installation: horizontal, vertical, swing base, torque arm.
7. Gear box products are 3 to 26 specifications, Bevel Gearbox deceleration drive series 1 to 4, speed ratio of 1.25 to 450; and R, K, S series combination to get a larger ratio.
Common gearbox lubrication methods are gear oil lubrication, semi-fluid grease lubrication, solid lubricant lubrication in several ways. For the seal is better, the speed is high, Bevel Gearbox the load is large, good sealing performance can be used gear oil lubrication; for the seal is not good, the lower speed can use semi-fluid grease lubrication; for oil-free occasions or high temperature occasions can use two Molybdenum sulfide ultrafine powder lubrication.
Gearbox is an important part of the mechanical transmission is widely used in a pair of gear meshing, due to the inevitable existence of the pitch, tooth and other errors in the course of the operation will produce meshing impact and gear meshing frequency corresponding to the noise , Friction between the tooth surface due to relative sliding friction occurs. As the gears are the basic parts of the gearbox drive, Bevel Gearbox reducing the gear noise is necessary to control the gearbox noise. In general, the gear system noise occurs mainly in the following areas:
1. gear design aspects. Improper parameter selection, Bevel Gearbox coincidence is too small, improper profile modification or no modification, gear box structure is unreasonable and so on. Gear processing base section error and tooth profile error is too large, the tooth side gap is too large, the surface roughness is too large and so on.
2. Gear train and gearbox. Assembly eccentricity, Bevel Gearbox contact accuracy is low, the parallelism of the shaft is poor, the shaft, the bearing, Bevel Gearbox the bearing rigidity is insufficient, the bearing rotation precision is not high and the gap is not proper.
3. Other aspects of input torque. The fluctuation of the load torque, the torsional vibration of the shaft system, the balance of the motor and other transmission pairs.
