Product Description
Double helical bevel gear and rack has the advantages of high coincidence, small axial load, high bearing capacity, and stable operation. It adopts the double helical gear base to transmit the torque of the main motor or motor unit to the roller. Advantages of the double helical gear: the double helical gear has high coincidence, and at least two teeth meshed at any time; the meshing process of the tooth quality inspection of the double helical cylindrical gear wheels is a transitional process, and the stress on the gear teeth is gradually from small to large, and then to small; the double helical gear has high bearing capacity and stable operation; the double
Advantages and Disadvantages of the Herringbone Gear Rack:
1. It can ensure a constant transmission ratio and can transmit the movement between two shafts with any included angle.
2. Features of large transmission power and efficient gear transmission. Gear transmission is used to transmit the motion and power between any two shafts. Its peripheral speed can reach 300m/s, the transmission power can reach 105KW, and the diameter of gear can be less than 1mm to above 150m. It is a widely used mechanical transmission in modern machinery.
3. Long life, stable operation and high reliability.
4. Since the tooth profile of the rack is straight, each point on the tooth profile has the same pressure angle and is equal to the inclination angle of the tooth profile. This angle is called the tooth profile angle and the standard value is 20掳.
5. The straight line parallel to the top line of the tooth and the tooth thickness equal to the width of the tooth slot is called the index line (center line), which is the reference line for calculating the rack size.
6. Any straight line parallel to the top line of the tooth has the same tooth pitch and module.
7. Almost any length of the stroke can be obtained by splicing.
8. For long-stroke applications, compared to synchronous belt and ball screw, gear rack is a very suitable choice.
Appilication of the Double Helical Gear Wheel:
1. It has a wide range of applications in factory automation, such as truss robot for automatic loading and unloading, stacking manipulator, and material handling devices.
2. It is suitable for factory automatic fast transplanting machine and industrial robot arm grasping mechanism.
3. It is suitable for CN machine tools, machining centers, cutting machines and welding machines with heavy load, high precision, high rigidity, high speed and long stroke.
4. It is suitable for fast and accurate positioning mechanism.
5. The characteristics of gear rack, such as fast moving speed, free splicing length and synchronization with thermal expansion effect of machine tool, can completely replace the application of ball screw in precision automation equipment and CNC machine tools.
Notice for the Spiral Helical Gear Rack:
For the rack and pinion transmission that starting transmission and with an impact load, the following aspects should be paid attention to:
1. Under the premise of structural allowance, the module m should be selected slightly larger, which is especially important for starting transmission with impact load.
2. The structure must have sufficient impact resistance and sufficient rigidity to ensure that the operation of rack and pinion.
3. The design speed shall not be too high.
4. It is best to design as a shifting gear and a negative shifting gear. Negative shifting will help improve the bending strength of the tooth root and improve the gear's ability to withstand impact.
5. The quenching depth of the tooth surface shall not to be too deep, generally 1/5m to 1/10m (m: modulus). It is necessary to maintain the core material with sufficient toughness to buffer external impact load.
6. The heat treatment hardness of the tooth surface shall not to be too hard, HRC30 ~ HRC35 is enough, and the tooth surface is too hard to crack the gear teeth under the impact load.
