【正文】 overload protection. However, hydraulic motor drive plex, the high cost of manufacturing, maintenance more difficult. Gear used motor oil, the volume of high efficiency, performance and impactresistant, easy maintenance, low cost, a 10 KW around the motor gear oil prices only with the power of the radialSema Da 1 / 10。 small size, light weight. A 10 KW gear around the weight of motor oil, with the only major power lowspeed torque motor of 1 / 18, the weight of the motor 1 / 13. Gear used motor oil, although lowerspeed reducer size large torque motor, but a small electric (MRHS5013type plane reducer transmission ratio i = 328). So can easily be motors, reducers, hydraulic Zhidong Fa, tight chain devices installed in the middletracked. In this way than on the technical performance of mechanical transmission, the economic indicators better than the lowspeed torque motor drive. So has a unique advantage. The walking speed in two ways: one is a variable pump. The other is the use or diversion of the flow and speed control programmes, such as the MRHS5013 type aircraft, that is, in the rapid mobilization of machinery, to stop carrying motor oil, only to run motor oil so that the boring machine has two Walking speed. 3 determination plete machine main technology senate parameter Mechanical Roadheader plete machine main technical parameter including size senate parameter (length width highly)。 weight parameter, parameter of movement and dynamic parameter. size parameters Complete machine length, width of the size directly related to its turning radius, Remended lightlength ≤ m, mediumlength ≤ m, heavy machine ≤ l0m, the corresponding width were ≤ m, ≤ m, ≤ 3 m. The plete machine relates its tendency, the static stability highly directly, the adaptation scope and passes quality, therefore lower better. The current development trend of Chinese and foreign models is the dwarf models, medium and heavyhigh ~ 2 m, special light, light machine the height of ~ m. Roadheader to dig the biggest section of roadway, the minimum height and width should be designed to meet the requirements of the mission. Undercover depth of 250 ~ 400 mm, ground clearance C = B/13 +84 (mm), B for the two track distance). Middlelong conveyor entrance to the expected high degree of the best 400 mm, length of track ground with the center distance L B ratio for L / B ≤ . weight parameters The plete machine dead weight is the mechanical roadheader an important parameter, the engine weight too is light, the work stability drops, when swinging cutting can occur fishtails the phenomenon, the cutting efficiency drops, truncation tooth rate of wear increase。 Heavyweight, poor mobility, flexibility to decline. The selfrespect as it may be w = (t) estimates, in the Ntype body for cutting power, kW。 V for the cutting head on average cutting speed, m / s。 can also be Roadheader with reference to the existing analog method to determine , machine(t) and cutting power (kW) ratio of to . For general coal, rock bottom, the allowable value ≤ MPa。 muddy for the water to soften the shale bottom, ≤ MPa. movement parameters Cutting the movement parameters: cutting head of the average cutting speed V: on the oneway coal and rock pressive strength of σ c ≤ 40 MPa, V = 3 ~ / s。 σ c ≤ 60MPa, V = 2 ~ / s, σ c 60MPa. V = l ~ 2m / s. But eventually cutting speed by cutting technology to determine. dynamic parameters Roadheaderdriven power sources are used Motors. Cutting power body size. In fact the general use of analogy, bined with roadheader some personality and experience factors to determine. Roadheader in the operating process, the vertical axis and the horizontal axisof the need for adequate cutting edge and push forward swing (horizontal and vertical) force. According to Russia (the former Soviet Union) in the laboratory test results that the cutting of coal and rock platts hardness f = 4 ~ 6 (equivalent to 0 C = 40 ~ 60MPa), grinding coefficient F = 5 ~ 7mg/mm2. Cutting the shaking force (traction) Pv = (1 ~ ) P, P = M / Rcp, in the Pcutting head for the average cutting edge。 Rcp cutting head for the average radius。 M for cutting the head of the rated torque. Cut the feeding of (axial thrust) R。 ( ~ ) Pv, this force should be no larger than the floor slippery track at the limits of traction. technical and economic indicators Q = (m3/min), in the sxcutting head for the verticalcross sectional area, m2: Vn for the cutting head of cutting swing speed, m / min. Roadheader designed life, in the international advanced products up to 3 to 5 years, during which the need of major repair or wells, the general domestic product for 1 to 2 years. 4 in accordance with design requirements. Determine the parameters of the main ponents and their relationship between the connector cutting agencies and technical parameters of the established link between 1) Cuttingagency technical parameters of cutting the head with the general pick for the doubleheaded or three spiral layout. Cutting head speed n = 20 ~ 65r/min, a sharp pick cutting the average speed V = ~ / s, cutting swing speed Vn = ~ l0m / s. Cutoff line from t = 20 ~ 50mm, (when cutting coal from the value of alltime for small value). Average singlepole/doublethrow force should reach: f4 grade coal and rock F ≥ 2500 N, f6 grade coal and rock F ≥ 5000 N, f8 grade coal and rock F ≥ 12020 N, pick the best angle for the installation of 45 176。 ~ 48 176。. 2) Cutting the link .Cutting agencies cantilever Chaxinginstalled in front of the fixedChaxing rotary table, the turret to the rack. According to cutting agencies in the course of operating the force and torque, the application of MT4751996 cantilevered Roadheader rot
