Description
Technical field
The utility model relates to a kind of gear-box, particularly a kind of mine hoisting gear-box.
Background technique
Mine hoist is the visual plant of coal in China, the mine resources such as coloured, metallurgical and energy extraction.Because plane table thermoconductivity meter has that volume is little, lightweight, transmission efficiency is high, vibration is little, stable working, noise are little, be convenient to the advantage such as installation and maintenance use, also be widely used on lift.Due to mine hoisting with gear-box generally have load large, start frequent, braking moment is large and require two work light characteristics, the Safety performance of product is required extremely strict, always be subject to each side in design, type selecting, manufacturing with aspect safeguarding and pay attention to.
The progress of technology at any time, the power of lift is increasing, and gear-box is transmitting under identical power conditions, and weight and volume is more and more less, and transmission efficiency is more and more higher, and structure is also more and more compacter.
The model utility content
It is reliable that technical problem to be solved in the utility model is to provide a kind of use, and impact resistance is strong, mine hoisting gear-box simple in structure.
For solving the problems of the technologies described above, the utility model clicks technological scheme and realizes: be comprised of with the Gear Planet Transmission part that is contained in support the brake component that is contained in frame, described frame flange connect is on support input end end face, described frame end face upper joint end cap, described frame is separated Gear Planet Transmission part and brake component, wherein:
brake component is by the input shaft that is contained in the end cap endoporus, be contained in the active V-type slotted disk on input shaft, driven V-type slotted disk, be placed in the steel ball between active V-type slotted disk and driven V-type slotted disk, friction pair and Returnning spring form, described steel ball is distributed on retainer, described steel ball number and master, driven V-type slotted disk groove number equates, described friction pair is comprised of the internal cones that is fixed on the frame endoporus and cone dish, the internal spline of described cone dish and driven V-type slotted disk and sun wheel shaft input shaft extension end external splines cunning are joined, described Returnning spring one end is close on the shaft shoulder of sun wheel shaft, the other end is close to cone dish and internal cones circular cone rubbing surface is compressed,
The Gear Planet Transmission part is comprised of sun wheel shaft, planet carrier, planet wheel, planet wheel shaft, output shaft and ring gear, described output shaft and planet carrier are integrally togather, its both sides are bearing in respectively in support and frame output terminal endoporus with bearing, and described ring gear is connected in the support endoporus with coupling.
Described ring gear cylindrical and support endoporus are slidably matched, and uniform metallic elastic thin walled tube coupling on slip surface is equipped with rubber core rod damping material in described metallic elastic thin walled tube coupling.
Compared with prior art, good effect of the present utility model is: because brake component is contained in retarder body end cap, thereby when braking no-spark, usability is reliable; Ring gear cylindrical and support endoporus cunning are joined, and with metallic elastic thin walled tube resilient connection, have greatly improved impact resistance; Simple in structure, the process for machining performance is good, low cost of manufacture.
