Received Date :2008.05 a 8-29 a Vol 29 ll of a 120TP EBJ boring machine running gear of the transmission system design - Liang Bin, et al Vo1. . 29No11 the need to redesign them. Figure 1 Schematic diagram of a primary gear reducer drive system design transmission type selection 1.1 boring machine according to the working characteristics of the work is less time each day, and short-term intermittent work, and the narrow space under the work of mine conditions, so the characteristics of gear should be: 1 short-term intermittent work, light weight, high transmission efficiency. The 3K (I) type of transmission is more suitable for short-term interruption of work, the transmission ratio, compact, light weight, so the selection of 3K (I)-type transmission, the transmission system shown in Figure 2. Figure 2 Schematic diagram of the new gear drive system design and calculation of 1.2 (1) known parameters Weight / t32 walking speed / m ・ min 3 hours of work, to mobilize when the 6 Track width / mm500 (2) the selection of crawler hydraulic motor institutions should meet the minimum traction boring machines operating on the maximum design slope, climbing and turning at the level of road conditions and other requirements,<a href="http://www.uggboots-guenstig.com" target="_blank" class="postlink">ugg boots sale</a>, the maximum traction force should be less than the adhesion at the level of the road track. Select the hydraulic motor according to the calculation model JMDG a 2-150. (3) The main parameters of each gear in Table 1. Table 1 The main parameters of gear design based on the use of boring machine operating conditions, the use of features for running gear, involute cylindrical gears in accordance with load capacity calculation method to calculate, for each level transmission and planetary gear drive straight to a reasonable level by level with teeth, each of the appropriate level of gear modification, and its calculation of the contact strength and bending strength calculation, the force analysis on the drive shaft for each level and strength calculation, were within a reasonable safety factor. The remaining parts are carried out strength check, including bearings, key verification,<a href="http://www.uggboots-billig.com" target="_blank" class="postlink">ugg boots deutschland</a>, has reached the requirements. 1.3 The choice of materials used under the conditions and stress gear needs, choose 35CrMo, 20CrNi3 carburizing steel spur gear and the sun gear and planetary gear planetary gear. In the case hardening of the material has good resistance to wear and after the bending strength, low temperature impact toughness. Structural features gear structure 2 shown in Figure 3, the hydraulic motor to power transmission through the splined input shaft to the reducer through 3K (I) type planetary gear transmission, the output from the outer ring gear, driving wheel running, that drive the crawler. Specific structural features are as follows: (1) planetary gear transmission with a 3K (I) type of transmission forms,<a href="http://www.cheapuggboots-uk.org" target="_blank" class="postlink">ugg boots uk</a>, compared with the previous speed reducer, which reduces the transmission links, more compact, smaller, more efficient transmission. (2) In order to solve the problem of tunneling machine running the brake, put the gear input gear of a pair of growth rate improves the speed of the brake shaft, thus reducing the braking torque, making for a smaller volume brake for effective braking. And the structure will be parallel to the brake and hydraulic motor arranged in the reducer end, full use of the space. (3) requires the whole structure of small gear in the design of the 3K (I)-type planetary gear reducer is optimized with,<a href="http://www.uggboots-billig.com" target="_blank" class="postlink">ugg boots billig</a>, the use of a high degree of modification, and made the corresponding check, to ensure the required transmission ratio circumstances, it makes the 3K (workers) the smallest planetary reducer. Figure 3 3 Conclusion of the gear structure is designed in a 12011P EBJ based on the type of boring machine, change the travel unit transmission forms, plus the ordinary gear reducer KH 2 a form of planetary gear transmission to hydraulic motors and 3K (I) planetary gear drive straight shaft coupling form. By 3K (workers) reducer transmission ratio, the characteristics of compact structure, in a relatively small space to achieve the entire power transmission, which effectively save space, improve efficiency, reduce the weight.
