Description

Large and medium speed reducer observation window

Technical Field

The utility model relates to the technical field of speed reducers, in particular to a large and medium-sized speed reducer observation window.

Background

The large and medium-sized speed reducer adopted in the metallurgical machinery industry is related equipment, various gears, shafts and bearings are arranged in the speed reducer, spare parts of the parts are very expensive, if large equipment accidents such as bearing damage, gear tooth breakage and the like occur, the maintenance time is long, the maintenance cost is high, and the production economic benefits of enterprises are seriously influenced, so that the daily point inspection, the periodic inspection and the special inspection of the speed reducer are the important matters of the work of mechanical point inspectors of the enterprises. The inspection of the speed reducer is the most visual and accurate inspection method except comprehensive judgment from sound, temperature, vibration and the like, and can see the meshing abrasion condition of the gear teeth, whether each oil supply point is smooth or not, whether bearings exist, gear tooth fragments, metal powder and the like. The original window plate of the speed reducer is shown in fig. 4, and is a square cover plate 12, a plurality of screw holes are uniformly distributed around the cover plate 12 and are connected with the speed reducer shell through bolts, and a pressed leather pad is arranged between the cover plate 12 and the speed reducer shell 1 to seal the speed reducer shell, so that oil leakage is avoided. This structure results in multiple screws being required to be removed for each inspection, and requires more than 30 minutes to clean the joint surface, glue, change the leather pad, etc. And the screw holes are easy to slide after being disassembled for a plurality of times, so that the leather pad is not tightly pressed and oil leakage is caused, and reworking secondary installation is caused. Because the production task is heavy, the daily repair time is short, the spot inspection work stop spot inspection task point is multiple in surface, the window inspection is carried out on more than ten speed reducers and nearly thirty windows in an enterprise, a large amount of time is consumed, and the inspection efficiency is low.

Thereby greatly improving the inspection efficiency.

The specific scheme of the utility model is as follows: the utility model provides a large and medium-sized speed reducer observation window, includes the speed reducer shell, and the speed reducer shell is equipped with the observation hole, and observation hole department is equipped with a bottom plate, and the bottom plate middle part is equipped with circular shape through-hole, through-hole and observation hole intercommunication, and the bottom plate outside is located through-hole department and is equipped with round supporting ring, and supporting ring department is equipped with detachable closing cap, and the closing cap inner is equipped with round drum, and the inner of drum stretches into in the through-hole, the outer wall and the through-hole internal face cooperation of drum, the outer lane of drum is equipped with round sealing washer.

Further, the outer wall of the support ring is provided with a circle of groove, the sealing cover is provided with a circle of cap peak, the inner wall of the cap peak is matched with the outer wall of the support ring, the cap peak is provided with at least one threaded hole, the threaded hole is provided with a locking screw, and the inner end of the locking screw extends into the groove to lock the sealing cover.

Furthermore, the sealing ring adopts a framework sealing ring.

Further, a plurality of threaded holes are formed in the periphery of the observation hole of the speed reducer shell, and bolts are arranged on the bottom plate corresponding to the threaded holes.

The utility model has the following beneficial effects: the observation window dismouting is more swift, and the operation is more convenient, save time, can guarantee simultaneously not reveal, has solved the inconvenient, time consuming laborious, the problem of easily revealing of observation window dismouting of prior art.

Detailed Description

Referring to fig. 1-3, the embodiment is a large and medium-sized speed reducer observation window, which comprises a speed reducer shell 1, wherein the speed reducer shell 1 is provided with an observation hole 2, a bottom plate 4 is arranged at the observation hole 2, a circular through hole is arranged in the middle of the bottom plate 4 and is communicated with the observation hole 2, a circle of supporting ring 6 is arranged at the position, which is positioned outside the bottom plate 4, of the through hole, a detachable sealing cover 7 is arranged at the position, which is provided with a circle of cylinder 11, the inner end of the sealing cover 7 extends into the through hole, the outer wall surface of the cylinder 11 is matched with the inner wall surface of the through hole, and the outer ring of the cylinder 11 is provided with a circle of sealing ring 5. Further, a circle of groove 9 is formed in the outer wall of the support ring 6, a circle of cap peak 10 is arranged on the sealing cover 7, the inner wall of the cap peak 10 is matched with the outer wall of the support ring 6, at least one threaded hole is formed in the cap peak 10, a locking screw 8 is arranged in the threaded hole, and the inner end of the locking screw 8 stretches into the groove 9 to lock the sealing cover 7. Furthermore, the sealing ring 5 is a framework sealing ring. Further, a plurality of threaded holes are formed in the periphery of the observation hole 2 of the speed reducer shell 1, and bolts 3 are arranged on the bottom plate 4 corresponding to the threaded holes. When the embodiment is used for the observation window on the vertical plane of the speed reducer, 1-2 skeletons are sealed and installed at the position, close to the bottom plate 4, of the inner end surface of the supporting ring 6, the sealing cover 7 is installed, the locking screw 8 is screwed down, and the inner end of the locking screw 8 is embedded into the groove 9; if the embodiment is used for the observation window of the horizontal position of the top surface of the speed reducer, the cover 7 is directly installed and the locking screw 8 is screwed. The framework sealing ring 5 is not required to be installed, because the outer edge of the cylinder 11 at the inner side of the sealing cover 7 and the through hole formed in the middle of the bottom plate 4 form clearance sealing, and after the pressure balance between the inside of the supporting ring 6 and the inside of the speed reducer is achieved, a shallow oil pool is formed in the supporting ring 6, so that oil cannot leak out. In the embodiment, when in inspection, only one locking screw 8 is required to be detached, the sealing cover 7 is pulled out, the internal condition of the speed reducer can be seen, the operation is convenient, the operation time for detaching the sealing cover 7 is greatly shortened, and the inspection work efficiency is improved.
