Abstract

A kind of speed reducer capable of preventing oil leakage, comprise upper and lower casing, driving gearshaft group, bearing, Sealing and spindle nose end cap composition, bearing outer ring coordinates with bearing support, described drive axle seat shaft hole inner wall offers multiple annular drain pan and at least one axial drain pan, axial drain pan communicates with multiple annular drain pan respectively, and the inner of axial drain pan communicates with in lower box.Retarder in the running, input end specific output end rotating speed wants high, the centrifugal force produced is also large, because of centrifugal force, lubricant oil the produced pressure that splashes in casing is that input end is greater than output terminal, and owing to devising a few road annular drain pan, the lubricant oil of splashing reduces pressure successively through multiple annular drain pan, flow back in lower box fuel tank by axial drain pan, thus prevent leakage of oil.Casing connecting part is also like this.Structure is simple, and can carry out in the lump when production and processing retarder axis hole and lower box junction plane, there is no impact to cost of production, producible benefit is obvious.

Description

A kind of speed reducer capable of preventing oil leakage

Technical field

The utility model relates to a kind of retarder, specifically a kind of retarder with oil-leakage-prevention function.

Background technique

Retarder is widely used in multiple fields such as mine, chemical industry, metallurgy, building.

Retarder is in operation process, and due to the effect of centrifugal force, lubricant oil can splash, and produce certain pressure from shaft end head and junction plane excessive and produce leakage of oil.Although shaft end head is provided with seal arrangement, but because of the compressing of its gear shaft group weight, in addition for a long time running and cause certain wearing and tearing of seal arrangement, certain gap will inevitably be produced, because operating lubricant oil produces certain pressure in splashing process, the lubricant oil in casing certainly will be caused to leak from shaft end head or junction plane.Along with retarder is longer for running time, leakage of oil is also more serious.

Retarder on-stream generation leakage of oil is very general.

Equipment oil leakage does not only reach the standard of perfect facility, and leakage of oil is a kind of waste to the energy, and be also a kind of pollution to environment, lubricant oil belongs to fire good in addition, also totally unfavorable to fire safety.

Model utility content

The purpose of this utility model, is to provide a kind of speed reducer capable of preventing oil leakage, and when retarder is in running order, non lubricant oil leaks, and not only saves lubricant oil, reduces environmental pollution, and favourable to fire safety.

The technological scheme adopted is:

A kind of speed reducer capable of preventing oil leakage, comprise upper and lower casing, driving gearshaft group, bearing, Sealing and spindle nose end cap composition, bearing outer ring coordinates with bearing support, it is characterized in that:

Described drive axle seat or transmission shaft hole inner wall offer multiple annular drain pan and at least one axial drain pan.Axial drain pan communicates with multiple annular drain pan respectively, and the inner of axial drain pan communicates with in lower box, forms mazy type oil drainage structure.

On lower box junction plane, within one week, offer casing circumference drain pan along lower box, casing circumference drain pan communicates with corresponding annular drain pan.On lower box junction plane, and be positioned at inside lower box circumference drain pan, offer multiple drain pan, one end of each drain pan communicates with casing circumference drain pan, and its other end communicates with in lower box.

The utility model advantage:

Retarder in the running, input end specific output end rotating speed wants high, the centrifugal force produced is also large, because of the reason of centrifugal force, lubricant oil the produced pressure that splashes in casing is that input end is greater than output terminal, owing to devising a few road annular drain pan, when the lubricant oil splashed reduces pressure successively through multiple annular drain pan, and flow back in lower box fuel tank by axial drain pan, thus prevent the generation of oil leakage phenomenon.Casing connecting part is also like this.The utility model structure is simple, and when production and processing retarder axis hole and lower box junction plane, can carry out in the lump, there is no that what affects to cost of production, producible benefit is obvious.

Fig. 2 is that the A-A of Fig. 1 analyses and observe enlarged diagram.

Fig. 3 is the B place enlarged diagram of Fig. 1.

Embodiment

A kind of speed reducer capable of preventing oil leakage, comprises retarder main body 1, is equiped with transmission shaft 3 in drive axle seat 6 axis hole on the lower box 2 of retarder main body 1, on transmission shaft 3, be equiped with bearing 4 and shaft end seal lid 5 successively, bearing 4 outer ring coordinates with drive axle seat 6 inwall, it is characterized in that:

Drive axle seat 6 shaft hole inner wall offers 3 annular drain pans, 7,3 annular drain pans 7 parallel; Drive axle seat 6 shaft hole inner wall axially offers an axial drain pan 8, and axial drain pan 8 respectively drain pan 7 annular with 3 communicates, and the inner of axial drain pan 8 communicates with in lower box 2.

On lower box 2 junction plane, within one week, offer casing circumference drain pan 9 along lower box, casing circumference drain pan 9 communicates with a corresponding annular drain pan 7; On lower box 2 junction plane, and be positioned at inside casing circumference drain pan 9, offer multiple lower box drain pan 10; One end of lower box drain pan 10 communicates with casing circumference drain pan, and the other end of lower box drain pan 10 communicates with in lower box 2.
