Advantages of pneumatic clutch
The specific forms of the plum coupling have the main forms:LMThe shape(Basic type)、LMDtype(Single flange type)、LMStype(Double flange type)、LMZ-Itype(Split brake wheel type)andLNZ-II(Full brake wheel type)。
Belt deviation phenomenon is the most common phenomenon encountered in the working process of coal mine belt machine,Once the Adelfalk belt machine belt deviation phenomenon,Light results in material withdrawal,Severe belt wear,Affect the normal production of the production line,Severe friction between the belt and the frame will make the belt soften or even burn a fire,Resulting in casualties among staff members。
Design in Taiwan KaiheKHRack and pinion,First need according to the condition(Such as:Moving load、Moving speed、Arrival distance)To select the modulus,The module determines whether the rack and pinion mechanism is capable of working,Its strong enough not to break teeth。
Linear guide rail to obtain better machining accuracy and maintain its performance characteristics,Dust prevention is a very key dominant way。For this kind of mechanical components with high precision requirements,Any bit of dust and impurities will result in poor condition,It disrupts the whole system of linear motion,Thus shorten the service life。In that way,About ShanxiSJSYSWhat are the best suggestions for the dust prevention work of linear guide rails?Xiaobian simple for everyone to explain。
Rated speed selection of Siemens motors,To be considered according to the requirements of the drag production machinery and the ratio of the transmission device。

NskDouble row deep groove ball bearings are the most common type of rolling bearings。The basic type of deep groove ball bearing consists of an outer ring,An inner ring、A set of steel balls and a set of cages。Deep groove ball bearing types are single row and double row two,The deep groove ball structure is also divided into two kinds of sealed and open structures,The open type means that the bearing does not have a sealed structure,Sealed deep groove ball is divided into dustproof seal and oil proof seal。
The direct cause of safety fusing in bright weft switching power supply:Switching tubePower thickness moduleRectifier diode breakdown100uf/400vLarge capacitor breakdown leakage,The internal degaussing resistance is broken。
