Q:When the coupling is linked, can the drive shaft be thinner than the motor shaft?: More consideration should be given to the load capacity of the transmission shaft (strength, rigidity, mechanical performance), and if the load is small and the shaft length is not long, the transmission shaft can be smaller than the motor shaft.

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?: Many manufacturers are now producing this kind of machine, that is, the rotor and the screw nut are made together

Q:What are the functions of an automobile powertrain? What is the function of each part of it?: Composition and distribution of automobile transmission system:The composition and layout of the automobile powertrain vary with the type of engine, the location of the installation, and the use of the car. For example, off-road vehicles are mostly driven by four wheels, and in the transmission system, the actuators and other assemblies are added. As for the vehicle with front lead, there is no transmission shaft in its drive train.

Q:What kind of lubricant does nylon transmission use?: If you really need lubricating oil, choose the lowest viscosity is good, must be less, prevent seepage to the product; vegetable oil, edible oil can also

Q:How to prevent the transmission shaft from breaking and falling off?: Must be maintained regularly in accordance with technical specifications. Make sure the parts are well secured and well lubricated.The strict implementation of the standard maintenance, maintenance in V type with a dial indicator measuring shaft bending, if more than 0.SInmSubject to correction.Lubricate the intermediate bearing periodically, and install the bearing cap properly, adjust it in use.Replace the worn cross axle, bearings and other transmission parts in time.In the use of vehicles, attention should be paid to starting, shifting smoothly, reasonably using clutch and brake to reduce the impact of power transmission.

Q:The axial force of this drive eliminates the problem of how to do it! Thank you for the exam tomorrow: It's too much trouble drawing you. Let's give you a train of thought.Bevel gear 1 and 2 drive the axis II to the right direction; in order to offset the force of the axis II, it requires the rotation of the helical gear to meet the gear 4 to gear 3 to the left of the force. (it's about coaxial steering.).

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: What do I do if I want the slot above to be horizontal?
