Analysis and Research on Cutting Spiral Bevel Gears

For spiral bevel gears, the small wheels are always cut by the development method, while the large wheels are cut by both the forming method and the non-expanding method. In the case of grinding a spiral bevel gear that is cut by the forming method, the gear is ground and ground using a cylindrical straight cup-shaped grinding wheel. When using this grinding method, the grinding wheel represents one tooth of the imaginary wheel, and the gear is ground and ground by the mutual movement between it and the gear groove to be ground, as shown in the previous figure. When grinding large gears that are cut by non-expanding method, grinding can be performed by the grinding method of the eccentric main shaft or the flared cup grinding wheel. With this method, it is necessary to provide the coolant and the removal of the grinding debris. Clearance.

Since the grinding teeth provide more stable precision and quality, and because of the computer numerical control system of the machine tool, the repeatability of batch and batch production can be achieved with a minimum of setting and adjustment conversion. The new Gleason grinding machine is now in front of us with high efficiency and high precision. The machine tool is equipped with two linear motors by using the following technical measures to achieve high-speed, high-precision machining. It can achieve fast feed speed, resistance, acceleration and positioning accuracy. The design of the machine tool as a heat balance structure is the result of intensive research on the static and dynamic performance of the machine tool in the machining process and the distribution of the cutting temperature.

In order to improve the machining accuracy of the machine tool, the three supporting parts at the bottom of the machine bed are designed as a whole-stitched structure with a peak-like shape to better support and adjust the machine tool. The machine selects the system and can monitor the machine vibration caused by the imbalance of cutting force during cutting. Thereby optimizing the processing process to ensure the high quality of the product.

The machine tool design also includes complete sealing protection measures for the linear guide to prevent the intrusion of debris and dust to extend the service life of the guide rail and maintain the consistency of machining accuracy. The machine is equipped with an optical scale to reliably measure the amount of movement of each axis. The machine has a wide processing range and can process parts of different sizes. The machine is equipped with an electric spindle with power, spindle speed and shank. The spare spindle speed is the edge, the shank is the spindle speed and the shank is one.

Electric Bike Helmet

When an accident occurs, the riding helmet can absorb most of the impact force and play a protective role of buffering and shock absorption, which can reduce the proportion of injured persons by 70% and the death rate by 40%. 2.5 times the helmet, fatal injuries without a helmet is 1.5 times that of wearing a helmet. For electric vehicle drivers, helmets are equivalent to the seat belts worn by car drivers, and they are the last line of defense for cyclists when they encounter danger.
