- Q: What are the most effective circumferential forces that can be transmitted by belt transmission?
- A - wrap angle on belt pulley, alpha =min (a_1, alpha _2), rad.A_1 = 180^ ~ - (d_d2-d_d1) 57.5^ ~ /aA_2 = 180^ ~ + (d_d2-d_d1) 57.5^ ~ /aD_d1 and d_d2 are a small pulley and pulley datum diameter. For the V belt, the reference diameter is the sheave width, and the width is equal to the diameter of the band width b_p.From the upper model, the minimum initial tension directly determines the magnitude of the critical friction force. It is also noted that increasing the friction coefficient (or equivalent friction coefficient) and the pack angle of the pulley can increase the critical frictional force, thereby minimizing the minimum Flali (F_0) _min value.
- Q: What are the main failure modes of belt drives?
- There are 2 main types: skidding and fatigue failureSkid: generally, when the force of transmission is greater than the sum of the friction between pulleys, overload, skid, transmission failure will occur.Fatigue failure: the belt cracks under the repeated action of stress, delamination, loosening, and fracture.
- Q: An object with a relatively 4m per second speed transmission belt, acceleration is 1m/s^2, the speed belt is 1m/s, and the motion in the opposite direction, now has a fixed point in the transmission A belt, A belt with mobile A, known distance of objects into the belt where the distance is 4m, for objects time to AIt's 4*T+0.5*1*t^2=4, but it really surprised me. Why is the speed 4? The relative speed of the belt is 3?But the teacher also said that this type of questions just to see, do not look at the transmission belt objects to relative 4 speed transmission belt, is calculated to 4? But always felt very contradictory? If so, then the people on the treadmill but practical and relatively static movement in motion
- The speed of known objects and the speed of the belt are all referenced by the earth
- Q: How do you calculate the torque of the belt?The structure of the design is shown in the figure,
- The shaft is a steel shaft with a solid diameter of 200. The outer ring is made of crimped material. The fabric density is 1.1, and the maximum crimp diameter is 1800
- Q: What are the common knowledge of driving belts?
- - do not scratch the belt so as to avoid premature damage to the belt. - avoid contact with chemicals (especially strong oxidizing acids, such as concentrated sulfuric acid). - try to avoid long-term contact with oil or water. Maintenance and replacement
- Q: The relation between the initial tension and the tension force, the relationship between the circumferential force and the effective tension in the belt drive
- Elastic slide: belt drive at work, from the tight side to the loose side, the belt is subject to changes in tension, so the band of elastic deformation is also changing. In belt transmission, the relative motion between the belt and the pulley due to the elastic deformation of the belt is called elastic sliding. The elastic sliding results in the circumferential velocity V2 of the driven wheel, the circumference speed V1 of the driving wheel, and the degree of velocity reduction can be expressed by sliding rate epsilon
- Q: As shown in the figure belt transmission device, wheel driving wheel, driven by a belt driven wheel rotate counterclockwise (no slippage between the belt and the belt wheel), two points on the P and Q direction respectively by friction wheels (is)A., Xiang Zuo, Xiang ZuoB. right and rightC. left, rightD. to the right, Xiang Zuo
- Where P is the driving wheel, the wheel with the movement of the conveyor belt, the conveyor belt wheel by relatively backward movement trend, Q where the driven wheel is moving on the conveyor belt is driven, the direction of friction.
- Q: What are the factors determining the optimum tensioning force in belt drives?
- It is related to friction coefficient, transmission wheel diameter, drive speed, length of belt and its material.
- Q: Type of transmission belt? Pictures? And the characteristics of each kind of belt?
- As the flat belt drive efficiency is low (usually about 85%), and occupies a larger area, therefore, from 1960s, the world's output has dropped year by year. At present, in developed countries, in addition to some agricultural machinery and textile machinery is still a small amount of use, has been in a state of being eliminated. On the other hand, in this period, the non - joint and hot - junction ring made of chemical fiber canvas and cord fabric became a great progress all over the world. With high strength, low noise, stable transmission, smooth transportation, flex, long life and no joint features such as, using the field continues to expand, and in the micro belt formed in the mainstream. 2. triangle belt: (1) narrow and wide v-belt. (2) small angle and big horn triangle belt. (3) flexible and punched v-belt. Triangle belt, also known as V belt, is the largest output belt, the most varieties and the most widely used products. Since 1917, the first American made car fan belt, after the early 20s began to spread to the agriculture machinery, more than half a century of development is very rapid, has become the mainstream of the drive belt. In the world's transmission belt, from the rubber consumption point of view, the triangle belt has now accounted for 65%, the tooth belt is 25%, flat belt has been reduced to less than 10%. At present, V-belt has become the main equipment of power transmission and speed change in various mechanical devices in the world. It plays a more and more important role in the fields of agricultural machinery, machine tools, automobiles, ships, office equipment and so on.
- Q: What are the types of transmission belts?
- 2, according to the working conditions of the gear, can be divided into:<1> open gear drive, the gear is exposed outside, can not guarantee good lubrication;<2> semi open gear drive, gear immersed in the oil tank, there is a shield, but not closed;<3> gear, gear, shaft and bearings are installed in the closed box, good lubricating conditions, Sha easy access, installation of precision gear transmission, good working conditions, is the most widely used gear.
