Q:When the coupling is linked, can the drive shaft be thinner than the motor shaft?: Coupling calibration is not required if the motor shaft and the drive shaft misalignment is that your motor installation seat problems both have, because you find it to two concentric since coupling is not so high the

Q:What part of the transmission mechanism of the walking conveyor?: Reducer selection principle: (1) according to the mechanical strength to determine the reducer specifications. Deceleration rated power P1N device is in stable load, work every day is equal to or less than 10h per hour, 5 times to start, allowing the starting torque for the contact strength safety factor of two times, the torque of the gear, the single one-way operation is 1, the failure probability is less than or equal to 1% is determined. When the load conditions are different in nature, work every day the number of hours is not at the same time, according to the work load of machine according to the classification of various factors are modified. The reducer two-way operation, will be seen P1N coefficient multiplied by 0.7 to 1, when the reliability KR reverse loads, reversing frequently, selected low for small value, and large value. Power down calculation: P2m=P2*KA*KS*KR, in which P2 is the working power; KA is the use factor; KS is the starting factor; KR is the reliable coefficient. (2) thermal power nuclear efficiency. Reducing the allowable heat power PG is applicable to the environmental temperature of 20 DEG C for 100% hour, continuous operation and power utilization (P2/P1N * 100%) is 100%, does not meet the above conditions, should be amended. (3) check the radial load on the shaft extension.

Q:Drive to do a linear movement of the spiral, look at the net efficiency of the ball screw rod is relatively high, if the ball screw to make the counter revolution, is the nut with a one-way bearing vertical fixation, screw up and down reciprocating motion, so that you can do, if possible, wire rod length 40CM screw diameter, 8MM, vertical pressure 80N of the screw, choose the lead big nut can make the speed to 700 RPM in the under pressure?: This usage is really special. I have 3 years to lead screw sales have not encountered.

Q:What are the functions of an automobile powertrain? What is the function of each part of it?: The power transfer device between the automobile engine and the drive wheel is called the driveline of the automobile. It should ensure that the car has the necessary conditions of traction and speed, and that between traction and speed change coordination function, so that the car has a good dynamic performance and fuel economy; should also ensure that the automobile can reverse, and the left and right wheels can adapt to cope with speed, and power transfer pattern need and smoothly with completelyrapid separation. The transmission system includes clutch, transmission, transmission shaft, main reducer, differential and half shaft parts.

Q:What kind of lubricant does nylon transmission use?: Nylon parts are generally used in low light load occasions, and then products require higher cleanliness, generally do not need lubrication;

Q:How to prevent the transmission shaft from breaking and falling off?: When the maintenance operation is not strictly carried out, the operating rules of the repair process are not strictly carried out, and the parts of the transmission shaft are deformed at random.The driver's improper operation, the drive shaft has a great impact on the result of damaged parts.The support deformation changes the vertical position between the drive shaft and the rear axle axis, twisting after mounting bolt flange in transmissionShaft abscission. Preventive measures:

Q:The axial force of this drive eliminates the problem of how to do it! Thank you for the exam tomorrow: Because the helical gear and worm gear can be processed in the direction is not clearly defined, so draw a worm gear direction, the other direction can be drawn by the direction of worm gear and the worm helical gear, thrust by 4 by thrust as long as the offset, it has achieved the design goal.Hope to be helpful to you, please adopt.

Q:This problem for a long time, a drive shaft with a key, how to fix the position after the rotation of concrete keyway, don't specify the rotation and rotation angle, through parallel or perpendicular to that location: I've seen other people, can first determine a plane for reference and choose the angle
