Abstract
The utility model discloses a high-speed gear vent hood which is reasonable in structure, capable of more effectively solving the problems of heat dissipation and lubrication of a high-speed gear of a speed reducer and a synchronizer. According to the technical scheme, the high-speed gear vent hood comprises a condensation pipe, wherein an upper hood body is arranged on the top of the condensation pipe, a flow guiding pipe is arranged on the lower portion of the upper hood body, the flow guiding pipe is arranged in the condensation pipe in a sleeved mode, a maze pipe is arranged outside the condensation pipe in a sleeved mode, and a reflowing hole is formed in the condensation pipe and located in the joint of the condensation pipe and the bottom of the upper hood body. The high-speed gear vent hood is reasonable in structure, capable of effectively solving the problem of heat dissipation and lubrication of the speed reducer and the synchronizer, capable of timely recycling lubrication oil and good in using effect, and maintenance cost of equipment is lowered.
Description
Technical field:
The utility model relates to the devices, particularly a kind of high gear vent hood that is applicable to speed reducer, synchronizer such as speed reducer, synchronizer.
Background technique:
Current coal, metallurgical, mine, the speed reducer that the industries such as machinery are used, synchronizer, especially on synchronizer, because the gear number of teeth is many, standard pitch circle is large, rotating speed is high, the gear teeth face linear velocity makes more than can reach 25 meter per seconds, the lubricant oil that is distributed in the flank of tooth has been subject to very large operating on centrifugal force, Surface of action produces amount of heat owing to being subject to local function simultaneously, can produce certain oil temperature raises, while adopting splash lubrication, the flank of tooth rotates in oil sump, in stirring the process of lubricant oil at a high speed, due to the acting of gear mesh lubricant oil, also can make oil temperature raise, the lubricant oil that temperature raises can produce a certain amount of mist of oil, make the box house pressure rise.Currently used heat radiation, ventilating mode often adopt bent-tube boiler structure or plain type breather plug, the heat radiation of this structure, ventilating mode there will be a large amount of leakage of oils and the lubricated oil condition of air contamination by dust when cooling in the running of being everlasting, can cause lubricating oil level fast-descending and lubricant pollution, need frequent make-up oil, caused inconvenience to the use of speed reducer, synchronizer, and user cost is higher.
Summary of the invention:
The purpose of this utility model is that design is a kind of rational in infrastructure, can more effectively solve high gear heat radiation and the lubricated high gear vent hood of speed reducer, synchronizer.
The technical solution of the utility model is, a kind of high gear vent hood, it comprises condensation tube, it is characterized in that: the top at condensation tube is provided with upper outlet body, be provided with honeycomb duct in the upper outlet body bottom, flow-directing shroud is contained in condensation tube, in the outer cover of condensation tube, the labyrinth pipe is housed, have return port on condensation tube, the position of return port is the position that condensation tube is connected with the bottom of upper outlet body.
The utility model is rational in infrastructure, can be effectively to the high gear heat radiation of speed reducer, synchronizer and lubricated, and can recycle in time lubricant oil, using effect is good, has reduced the maintenance cost of equipment.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, a kind of high gear vent hood, it comprises condensation tube 3, be provided with upper outlet body 2 at the top of condensation tube, be provided with honeycomb duct 4 in the upper outlet body bottom, flow-directing shroud is contained in condensation tube, in the outer cover of condensation tube, labyrinth pipe 1 is housed, have return port 5 on condensation tube, the position of return port is the position that condensation tube is connected with the bottom of upper outlet body.The utility model in use, lubricant oil evaporates into mist of oil because of high temperature, when mist of oil diffuses in honeycomb duct by condensation tube, become lubricant oil through the supercooling meeting, again flow back to the high gear of speed reducer, synchronizer, when the space of part mist of oil between condensation tube and honeycomb duct exhales, cooling through the labyrinth pipe on vent hood, become again lubricant oil again, flow back to the high gear of speed reducer, synchronizer through return port.
The utility model can effectively improve the lubricating efficiency of the high gear of speed reducer, synchronizer, and has reduced the user cost of lubricant oil, has improved the utilization efficiency of equipment.
