/mechanical/machine/4854.html Design of automobile differential detection control system [automobile] 06-05 The assembly quality of automobile rear axle differential is an important factor affecting the performance of the whole vehicle. The assembly quality of automobile rear axle is mainly affected by two factors, one is the assembly quality of the main gear assembly, and the other is whether the driving gear and the driven gear in the differential are well meshed. The structure of rear axle differential room is complex, and the measurement is inconvenient. The traditional measurement methods are manual measurement and some ...
/mechanical/auto/4254.html Design and analysis of the reducer driven by the mining monorail crane (excellent) 9734 [Mechanical] 05-2 1 Abstract: The mining monorail crane is a new underground transportation system, which is popular because of its smooth transportation and low requirements for the roadway environment. However, at present, there are not many domestic manufacturers of monorail cranes, and the products are single, with small bearing capacity and short service life, which seriously affects the application and promotion of domestic monorail cranes. I chose the graduation design of monorail crane this time, ...
/mechanical/machine/4204.html Design of scraper conveyor for mining ☆ [machinery] 05- 18 Abstract Scraper conveyor is a kind of continuous transportation machinery with flexible traction, which is arranged in coal mining face and mining roadway to transport coal. Its traction mechanism is a scraper chain, and its bearing device is a middle groove, and the scraper chain is installed on the groove surface of the middle groove. The middle trough is laid along the whole transportation route, and the scraper chain is connected into a closed shape around the nose and tail sprocket, which is put into the middle trough with the roller for coal mining. ...
/mechanical/machine/4196.html graduation design of three-ring reducer (planetary gear transmission with less tooth difference) [mechanical] 05- 16 Abstract The three-ring reducer is a new gear mechanism, and its basic structure consists of a low-speed shaft, two high-speed shafts and three rotating ring plates. The shafts are all arranged in parallel, and the same two high-speed shafts drive the three transmission discs to move in plane with a phase difference of 120, and the transmission ring discs mesh with the gears on the low-speed shafts to form a large transmission ratio. The shaft ends of each shaft can be independent or simultaneous. ...
/mechanical/machine/4183.htmldesign of control system for automatic detection and assembly test-bed of light vehicle differential assembly [automobile] 05- 1 1 The assembly quality of automobile rear axle differential is an important factor affecting the performance of the whole vehicle. But up to now, in order to meet the assembly quality requirements of differential main gear assembly, most manufacturers first select the types and number of gaskets through experience, and then determine the correctness of gasket selection by detecting the pre-tightening torque after press-fitting. If the pre-tightening torque is too large or too small, they should all be ...
/mechanical/auto/4168.html overall design of gearbox reducer [machinery] 02-07 Abstract This graduation project is an independent and complete mechanism driven by gears enclosed in a rigid shell. Through this design, we can master a set of design and methods of general simple machinery and form the general parts of reducer. This graduation project mainly introduces the type, function and composition of reducer, and makes full use of the knowledge learned. Such as: machine ...
/mechanical/machine/3748.html Design of two-stage cylindrical gear reducer (with defense record) [Mechanical] 12- 15 gear transmission is the most widely used transmission form in modern machinery. Its main advantages are: ① the instantaneous transmission ratio is constant, the work is stable, the transmission is accurate and reliable, and the motion and power between any two axes in space can be transmitted; (2) wide range of power and speed; ③ High transmission efficiency = 0.92-0.98; ④ Reliable operation and long service life; ⑤ External contour ...
/mechanical/machine/3573.htmlDesign of single-stage cylindrical gear reducer [mechanical] 1 1-03 Today's reducer is developing in the direction of high power, large transmission ratio, small volume, high mechanical efficiency and long life. The conjoined structure of reducer and motor is also a form of vigorous development, and products of various structural forms and power models have been produced. In recent ten years, due to the development of modern computer technology and numerical control technology, machining accuracy and efficiency have been improved. ...
/mechanical/machine/3355.htmldesign of double-tooth reducer [mechanical] 07- 16 1. Drawing up the transmission scheme In order to estimate the total transmission ratio range of the transmission device and select the appropriate transmission mechanism and transmission scheme, the rotation speed nw of the driving drum can be calculated according to the known conditions, that is, V =1.1m/s.d = 350 mm; NW = 60 *1000 * v/(∏ * d) = 60 *1000 *1(3.14 * 350) The general synchronous speed is1050. ...
