Abstract
The utility model relates to a kind of for the oil-leakage-prevention speed-change gear box on batcher, comprise the casing that is arranged at base top by back shaft, described back shaft is vertically fixed on described base, and penetrate described casing by the through hole of described bottom half, be connected with the transmitting assemblies in being arranged on described casing, described back shaft is arranged with bearer ring at described lead to the hole site place, between described through hole and described bearer ring, is equipped with oil sealing.Adopt after technique scheme, because hardness and the surface density of bearer ring are higher, not easy to wear, and the surface of bearer ring is comparatively smooth, can effectively reduce the leakage of lubricant oil, simple in structure, good sealing effect, back shaft still can be used conventional cast iron quality simultaneously, and cost is lower.
Description
Technical field
The utility model relates to a kind of speed-change gear box, especially a kind of for the oil-leakage-prevention speed-change gear box on batcher.
Background technique
Gear-box is widely used in various electromechanics and transmission device, is an important mechanical part, if batcher is exactly mainly to drive granny rag cylinder and volume portion rollers running to realize winding cloth function by speed-change gear box.The friction producing in the running in order to reduce the inner member of gear-box, general meeting charging-up lubricant oil in gear-box, in order to prevent that oil leak from causing gear-box internals to be damaged, generally on the back shaft of gear-box bottom, seal ring is set, but this sealing means is higher to parameter requests such as the precision of the back shaft coordinating with it and surface roughnesses, tradition makes the back shaft of cylinder iron manufacturing because its hardness is lower, easily wearing and tearing, easily cause oil leak, and adopt Bearing Steel that hardness is higher as the material of doing back shaft, its material and manufacture cost all can significantly rise.
Chinese utility model patent ZL201120020665.0 discloses a kind of helical sealing structure of gear-box, by being arranged on the spiral chute of end cap bore area, reverses vertically, utilizes its rotation centripetal force that lubricant oil is limited in gear-box.But the gear-box of this structure is under out-of-operation state, and the lubricant oil of gear-box inside can ooze along spiral chute, when turn round next time, need charging-up lubricant oil again, convenient not.
Chinese utility model patent ZL200920182024.8 discloses a kind of change gear box for cloth rolling machine of oil-leakage-prevention, by an end face being set higher than the leak-stopping boss of driving bevel gear tooth portion, prevents that the lubricant oil in gear-box from leaking outside.But because this gear-box need to arrange in inside a leak-stopping boss, take the inner space of gear-box, make the structure complicated between the inner dirivig member of gear-box.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, good sealing effect and lower-cost oil-leakage-prevention speed-change gear box.
To achieve these goals, the utility model adopts following technological scheme:
A kind of oil-leakage-prevention speed-change gear box, comprise the casing that is arranged at base top by back shaft, described back shaft is vertically fixed on described base, and penetrate described casing by the through hole of described bottom half, be in transmission connection with the transmitting assemblies being arranged in described casing, described back shaft is arranged with bearer ring at described lead to the hole site place, between described through hole and described bearer ring, is equipped with oil sealing.
As further improvement of the utility model, interference fit between described bearer ring and described back shaft.
Adopt after technique scheme, because hardness and the surface density of bearer ring are higher, not easy to wear, and the surface of bearer ring is comparatively smooth, can effectively reduce the leakage of lubricant oil, simple in structure, good sealing effect, back shaft still can be used conventional cast iron quality simultaneously, and cost is lower.
accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oil-leakage-prevention speed-change gear box.
In figure, indicate corresponding as follows:
1-back shaft; 2-base;
3-casing; 31-through hole;
32-transmitting assemblies; 33-upper cover;
4-bearer ring; 5-oil sealing;
6-bearing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Oil-leakage-prevention speed-change gear box the first embodiment of the present utility model as shown in Figure 1, comprise the casing 3 that is arranged at base 2 tops by back shaft 1, back shaft 1 is vertically fixed on base 2, and penetrate casing 3 by the through hole 31 of casing 3 bottoms, be in transmission connection with the transmitting assemblies 32 being arranged in casing 3, in the present embodiment, back shaft 1 also passes from the upper cover 33 of casing 3 through casing 3, and the material of back shaft 1 is common cast iron.Back shaft 1 is the gear-driven Placement of routine with the Placement of transmitting assemblies 32, is not described in detail in this.Back shaft 1 is arranged with bearer ring 4 in through hole 31 positions, and in the present embodiment, bearer ring 4 is columnar structured, and its material is the Bearing Steel that hardness is higher.Between through hole 31 and bearer ring 4, be equipped with oil sealing 5, interference fit between bearer ring 4 and back shaft 1.During speed-change gear box work, base 2 and back shaft 1 are motionless, transmitting assemblies 32 rotates around back shaft 1 with casing 3, for the stability of guaranteeing that casing 3 rotates, below oil sealing 5, be also provided with a bearing 6, bearing 6 can directly be set on the lower end of back shaft 1, but is preferably set on bearer ring 4, in the present embodiment, bearing 6 is set on bearer ring 4.
By reference to the accompanying drawings the utility model has been done to detailed explanation above; but mode of execution of the present utility model is not limited in above-mentioned mode of execution; those skilled in the art can make various distortion to the utility model according to prior art; as adopting sheet rubber to replace oil sealing 5 in above-described embodiment etc., these all belong to protection domain of the present utility model.
Claims (2)
1. an oil-leakage-prevention speed-change gear box, comprise the casing that is arranged at base top by back shaft, described back shaft is vertically fixed on described base, and penetrate described casing by the through hole of described bottom half, be in transmission connection with the transmitting assemblies being arranged in described casing, it is characterized in that, described back shaft is arranged with bearer ring at described lead to the hole site place, between described through hole and described bearer ring, is equipped with oil sealing.
2. oil-leakage-prevention speed-change gear box as claimed in claim 1, is characterized in that, interference fit between described bearer ring and described back shaft.
