2=SimSun summarizes the characteristics of the hall star speed reducer and its application examples in the rotary drill.
1 Overview Rotary drilling rigs are mostly used in foundation engineering. Unlike other high-precision engineering machinery, the degree of specialization is not high. It is the development of rice in constant practice and innovation. In the construction process of the total 1 turn rig, the speed of the turntable is not high, which requires a large reduction ratio. At present, most turntable rotary drilling rigs in the mountain field use a long deceleration chain to achieve the purpose of deceleration, and there are mechanical transmission chain cumbersome machinery. The fault is multi-noise, the use efficiency is low, and the performance of the whole machine is unstable. Aiming at the current demand and demand potential of the market, simplifying the mechanical transmission chain of the rotary drilling rig, applying the transmission ratio, large structure, compact size, small transmission efficiency, single stage to reach 9699, and other characteristics of the planetary reducer, the effect is clear, our factory timely pushes the new The generation of 132 type 1 rotary drilling rig and planetary reducer achieved the expected design effect through the application on the 132 rotary drilling rig.
2 planetary reducer in the mechanical manufacturing industry, it is increasingly expected to achieve high-power high-efficiency transmission under the conditions of small size and quality, and the use of the hall star train can better meet this requirement. Compared with the fixed-axis gear transmission, the planetary gear transmission has the advantages of small volume, light weight, large load capacity, high efficiency, and stable operation.
Planetary gear train means that one or one of the gear trains in the train wheel rotates during transmission. Structure Court 1.
It can be seen from 1 that the planetary gear reducer, hereinafter referred to as the planetary reducer, can be uniformly distributed on the circumference of the center wheel by using a plurality of planetary gears. In this way, several planetary wheels can share the load to reduce the gear size, and at the same time, the meshing can be balanced to reduce the force in the main bearing and increase the smoothness of the operation.
In addition, in the planetary reducer for power transmission, almost all of them are internally twisted, which improves the utilization of space, and the input shaft and the output shaft are in a curve, so the radial scale of the star reducer is very tight. Our factory developed and developed a series of reducer for the complex transmission efficiency of the engineering rig drive chain. The reducer adopts the infinite life design principle and the ball is hard cast iron. Precision cast housing. The dense ten design is directly lubricated by the oil filling port, which is simple and convenient. The sun gear and the planetary gear are made of special materials by quenching and tempering carburizing and hardening grinding. The input and output shafts are supported by strong and tough bearings to increase wear resistance and extend. The service life is used; the computer simulation test is used in the design, the material rigidity requirement and the gap control are fully optimized, and all digital detection and control are performed, thus obtaining a high positioning precision range and a sophisticated gear professional processing. Experience, reliable tooling and inspection equipment ensure that the noise generated by gear meshing is minimized, and the meshing accuracy and transmission efficiency are improved.
The basic parameters of our series series hall speed reducer are as follows, the maximum input power is 901; the maximum output torque is 9600 and the second page is made on page 245. Li Qingbin, 136586317, Jinan City, Shandong Province, 1979, male Han nationality, Shandong Yucheng people, Assistant engineer of Shandong Geological Prospecting Machinery Factory, majoring in mechanical engineering, engaged in research and development of engineering machinery geological machinery.
The combination of the core and the application of the core will be a very effective medium with strict requirements on the cleanliness of the medium. Therefore, the reliability and life of the air-drilling hammer have been confirmed by practice, and the rope core is drilled. Technology is also a very mature technology, and the organic combination of the two will produce clear technical benefits in geological prospecting and drilling construction in arid waters. This new type of cockroach! . The structure began to trial production.
3 Conclusion Due to the geological conditions and geographical environment of special landscape areas, it has brought great difficulties to the use of liquid as a circulating medium for drilling construction, and Ningqi as a ubiquitous special medium provides material for human and water-free areas to carry out drilling activities. Guarantee. Therefore, the advantages of air should be fully utilized. Taking the six-drilling technology of sampling and taking the measures, the drilling of the ground will certainly play a role in accelerating the exploration of geological minerals in the arid regions of western China.
The main technical parameters of Ding 320 drilling rig are as follows: drilling is 0.82.21; the depth of the boring is 80; the rotation speed of the turret is 8.125839.21 plus the output torque is 40, and the lifting capacity of the main hoist is 30. The lifting capacity of the auxiliary hoist is 30 520. The input speed of the rig is 144,1. If the output speed of the rig is compared with the output speed of the turntable, a large reduction ratio is required. At present, the rotary rigs on the market mostly use the stage gear reducer, the graded turntable or the stage gear reducer to increase the speed of the turntable, which causes the drive chain to be cumbersome. Unfavourable factors such as large space occupation and manufacturing difficulties. The application of the planetary reducer shortens the transmission chain, reduces the probability of failure, increases the operating space, and enhances the stability of the whole machine. The transmission chain clutch gearbox 4-axis planetary reducer + turntable 1 is currently The drilling rig has been produced and put into use at the site of the Huanghe Bridge in Jinan. During the continuous construction process, there is no abnormality in the planetary reduction gear, 7 full 0 price; æ²² working conditions, 32 bar machine has drilling stability compared with similar drilling rigs The advantages of low noise construction and convenient operation have been well received by users.
4 Conclusion Planetary deceleration has many advantages in mechanical transmission, but its structure is complex. The viscosity requirements, thus bringing certain difficulties to the manufacturing, with the enhancement of China's machining capacity, the quality of planetary deceleration products is 1 transportation. 1 course machinery and so on.
