The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on the eccentric sleeve 2.

Selection of LED light drive power The choice of LED lamp power supply is mainly considered from the output voltage, output current, and corresponding power wattage of the power supply. LED power supply generally has two types of constant current source output and constant voltage source output. First, for the LED power supply output by constant current source, we mainly consider its output voltage. For LED power drivers that output the same current, its output voltage It is also different, so when choosing a constant current LED power supply, it should be consistent with the working voltage of the LED lamp. For example, for a constant current LED power supply with a rated current of 200 mA to 300 mA, its output voltage is between 9V and 13V. The range between 10V and 25V, the range between 24V and 42V, the range between 45V and 63V, etc., so we choose this power supply to consider its output voltage range.      Similarly, for the constant voltage source LED power ...

Centrifugal fan is only one of many fan products, it has good performance, which is also closely related to the design of its blades. The same centrifugal fan is configured with different blade types to meet different application requirements.   1. Backward curved fan blades   This kind of blade can also be divided into single-plate type and wing type. The backward-curved single-plate blade has large structure size, low pressure coefficient and high efficiency. Therefore, the dynamic pressure accounts for a small proportion of the total pressure. Suitable for heavy wear, i.e. relatively high price. Backward curved wing blades have the same characteristics and should be the most efficient.   2. Forward curved blades   The blade structure of the forward curved blade is generally smaller, the pressure coefficient is higher, and the efficiency is generally lower. The dynamic pressure accounts for a large proportion of the total pressure, but it has the advantage of low ... Continue reading →

The difference between the cooling fan ball bearing   The cooling fan has single ball and double ball bearings, which can be selected according to different needs.
