Abstract
The invention relates to a large gear ring lubrication seal device and particularly relates to a gear lubrication seal mechanical device which recovers and effectively seals lubrication oil of large gears to reduce the environment pollution. The device is to solve the main technical problem of prior edge transmission rotary kiln large gear ring lubrication sealing. By means of the device, the structure is simple, the device is convenient to mount, the effective recovery of lubrication oil is increased, lubrication oil seal loads of a sealing body are reduced, and the pollution of lubrication oil to the environment is reduced.
Description
Technical field
Patent of the present invention relates to a kind of bull gear lubricating and sealing device, specifically, is that a kind of lubricant oil to gearwheel reclaims and effective sealing and a kind of mechanical device of minimizing environmental pollution.Be applied to cement building material industry.
Background technique
Rotary kiln is equipment very important in manufacture of cement, and it is bearing calcination of cement clinker the most complicated most important manufacturing process, is the process of unique qualitative change in whole production, and it has decisive to the output of cement.Bull gear is as the key component of rotary kiln transmission, and the quality of its service condition directly affects the working efficiency of complete machine.Therefore, the effective excellent sealing of bull gear is just seemed to particularly important.
At present, the gear of the most of rotary kilns of China adopts axial seal, radial seal, has the sealing of the felt of use or labyrinth seal etc.But using effect is not very desirable, there will be larger oil leakage phenomenon between seal, and environment is caused to larger pollution, and dust etc. also easily enters bull gear, thus the wearing and tearing of aggravation gear.
Summary of the invention
The main technical problem to be solved in the present invention is the lubrication and seal of existing Edge-Transmission big gear ring of rotary kiln, design is a kind of simple in structure, easy for installation, the effective recovery, the sealing burden of minimizing seal to lubricant oil that strengthen lubricant oil, reduce the lubricant oil constructional device of environmental pollution to external world.
Gearwheel seal oil device of the present invention, comprises case, trim ring, seal ring, bull gear, flinger ring, felt, oil sump tank, protective housing etc.
Its working principle is that most of fluid reclaims through the oil return groove of special formation, reduces lubrication oil consumption, alleviates the sealing burden of seal ring.Between sealing surface, adopt flinger ring, can effectively prevent the leakage of lubricant oil.That this seal arrangement has is simple in structure, easy for installation, consumptive material is few, reclaim oil mass large, pollute the advantages such as little.
Accompanying drawing explanation
Fig. 1 is the structural drawing of a kind of enforcement of the present invention.1-case, 2-trim ring, 3-seal ring, 4-bull gear, 5-flinger ring, 6-protective housing, 7-felt collar, 8-oil sump tank
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
This bull gear seal oil device relies on trim ring that seal ring is pressed on flinger ring while installation, and seal ring (nitrile butadiene rubber making) matches with flinger ring.
When use, be sprayed onto by lubricating fitting fuel feeding between the mesh tooth face of large small gear, reduce the wearing and tearing between the flank of tooth, take away heat simultaneously, carry out cooling to bull gear.
Lubricant oil after use, under the effect of the bull gear of self gravitation and rotation, is encountered after encloser inner wall, and most of fluid flows down along inwall, and the special oil return groove III (flinger ring both sides have) forming through flinger ring, flows to oil sump tank.
Under particular channel I (the case both sides have) effect of another part fluid on case, this part fluid flow back into oil sump tank, and part fluid gets rid of to flinger ring outside, and through groove, II flow back into oil sump tank.
Also have the gap of small part fluid between seal ring and flinger ring front cover to enter between seal ring and felt collar.Due to the effect of fluid damping, between sealing surface, form sealing, stop fluid to outward leakage.
Most lubricant oil is got back to oil sump tank through oil return trench flow, has greatly alleviated the sealing burden of seal ring, can effectively play the effect of sealing.
Whole device sealing using effect is more satisfactory, and fluid amount of leakage is few, and recovery utilization rate is high, and environmental pollution is little, simple in structure, easy for installation.
Claims (3)
1. a kind of gear lubricating and sealing arrangement of the present invention, comprises case, trim ring, seal ring, bull gear, flinger ring, felt, oil sump tank, protective housing etc.Its working principle is that most of fluid reclaims through the oil return groove of special formation, reduces lubrication oil consumption, alleviates the sealing burden of seal ring.Between sealing surface, adopt flinger ring, can effectively prevent the leakage of lubricant oil.
