Syringes are CE,FDA approved. And we supplied main nations in the world.
- 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: 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?
- But the rod itself can not be subjected to radial force, otherwise the life will be greatly reduced.Specific circumstances of specific analysis.
- 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: 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
- 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: What are the functions of an automobile powertrain? What is the function of each part of it?
- Rear drive - RR: rear engine, rear wheel driveThis type of arrangement is adopted on large passenger cars, and a small number of mini and light sedans are also adopted. The rear engine, the front axle is not easy to overload, and can make full use of the trunk area, also can effectively reduce the floor height or the middle of the bus to make full use of the space below the floor luggage, but also conducive to reduce the impact of high temperature and noise of engine drivers. The disadvantage is that the engine cooling conditions are poor, some of the faults in driving are not easily detected by the driver. The long distance operation also makes the control mechanism complex and inconvenient for maintenance and adjustment. But because of its outstanding advantages, it is used more and more in large buses.
- Q: When the coupling is linked, can the drive shaft be thinner than the motor shaft?
- Actually, the problem is mechanical mechanics.On the one hand, the size of the drive shaft in addition to considering the matching of 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.
