Abstract
The utility model relates to a novel rotary speed reducer with a sealing loop, which is characterized in that the sealing loop made of steel is additionally arranged in a second sealing ring and between the outer cylindrical surfaces of an output shaft and hard chromium is plated on the outer cylindrical surfaces. The rotary speed reducer has the following advantages: after the sealing loop is additionally arranged, as the hard chromium is plated on the outer cylindrical surfaces, the novel rotary speed reducer has high hardness, is wear-resistant and can cause little wear, the sealing ring cannot be easily damaged, the sealing effect is good and the service life of the sealing ring is prolonged; when in maintenance, only the sealing loop and the sealing ring need to be replaced, so that the maintenance is simple and the cost is low.
Description
Technical field
The utility model relates to the rotary reducer field in the mechanical transmission, is a kind of novel rotation speed reducer that seal ring is arranged concretely.
Background technique
Original speed reducer second road seal ring directly contacts with output shaft, because the existence of frictional force between seal ring and the axle, behind the operation certain hour, output shaft and seal ring contact segment all have wearing and tearing in various degree, and ring wear is accelerated, sealing was lost efficacy easily, produced oil leakage phenomenon; Output shaft is repaired difficulty, maintenance cost height.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model provides a kind of good sealing effect, and long service life is keeped in repair the easy novel rotation speed reducer that seal ring is arranged.
For achieving the above object, the technical solution that the utility model adopted mainly comprises: the second road seal ring, seal ring, output shaft.
A kind of have the novel rotation speed reducer of seal ring it is characterized in that: in the second road seal ring, between the output shaft external cylindrical surface, increase seal ring, the sealing ring is a steel part, the outer cylinder surface hard chromium plating.
Described a kind ofly have the advantage of the novel rotation speed reducer of seal ring to be: after increasing seal ring, because the outer cylinder surface hard chromium plating, hardness is higher, and is wear-resisting, and it is less to wear and tear, and is not easy to damage seal ring, and good sealing effect has prolonged working life of seal ring.During maintenance, only need to change seal ring and seal ring, easy to maintenance, cost is low.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
Fig. 1 reference character is as follows: the second road seal ring 1, seal ring 2, output shaft 3.
In the structural drawing of a kind of novel rotation speed reducer that seal ring arranged shown in Figure 1, its main structure comprises: in the second road seal ring 1, between output shaft 3 external cylindrical surfaces, increase seal ring 2.
Rotary reducer is vertical installation when using, and during operation, the lubricated of each bearing of top and gear is flooding system lubrication, by the oil lubrication in the upper plenum, and by the first road seal ring sealing; A nethermost bearing on the output shaft 3 is by the grease lubrication in the following cavity, by 1 sealing of the second road seal ring.
Claims (3)
1. the novel rotation speed reducer that seal ring is arranged is characterized in that: be made up of the second road seal ring, seal ring, output shaft; In the second road seal ring, between the output shaft external cylindrical surface, increase seal ring.
2. a kind of novel rotation speed reducer that seal ring is arranged according to claim 1, it is characterized in that: described seal ring is a steel part.
3. a kind of novel rotation speed reducer that seal ring is arranged according to claim 1 is characterized in that: described output shaft outer cylinder surface hard chromium plating.
