Abstract
The utility model discloses a roller assembly for an electro-hydraulic gate. The roller assembly comprises a main shaft, the main shaft is sequentially provided with a first step face, a second step face, a third step face, a fourth step face and a fifth step face from right to left in the axial direction, the second step face and the third step face are respectively sleeved with a sleeve, the sleeves are variable-diameter sleeves, the sleeves are in clearance fit with the second step face and the third step face, a gate frame is disposed outside the fourth step face, threads are arranged on the outer side of the fifth step face, and the fifth step face is provided with a nylon nut matched with the threads. Compared with the prior art, replacement of the roller assembly can be reduced to the largest extent, a gate device operates safely and stably, and the service life of the gate is prolonged.
Description
Technical field
The utility model relates to joining in transportation system, feed control field, particularly a kind of electric liquid gate roll wheel assembly.
Background technology
At present, the material in the production of domestic bulk material, storage, transportation is joined, feed is most adopts electronic, electric hydraulic brake gate control; And the slider roller that supports flashboard in gate is very crucial parts, when gate open and close, be all the support member of load-bearing.To bear gate own wt, bear again the impact force of falling material.
For example the gate in coal bunker is closed, and when Hatch Opening needs discharge shutter to open, the flexible rotating of roller is very important, because of the weight of material and the pressure that bear very large; After gate is opened, in feed process, roller is exposed in material flow, can be subject to the impact of material flow and friction and impaired, affects the normal use of equipment.
Roller in existing most equipment using in valve system all cannot not given roller grease up when not shutting down, not dismantling, and roller 45 steel or the Q235 materials of adopting are made not wear-resisting more; when valve system is opened, resistance is large; dumb, maintenance time is long, and application life is short.Separately have because of the roller strength deficiency in valve system, sliding outer cover is narrow, occurs gate dropping situations during operation, has caused serious production accident.
Summary of the invention
The purpose of this utility model be to provide a kind of to valve system with stable operation and the electric liquid gate roll wheel assembly that supports reliably.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of electric liquid gate roll wheel assembly, comprise main shaft, described main shaft sets gradually First terrace, second step face, the 3rd step surface, the 4th step surface and the 5th step surface outward from right to left vertically, the outer sheathed overcoat of second step face and the 3rd step surface, overcoat is reducer socket, and overcoat and second step face and the 3rd step surface are matched in clearance, and the 4th step surface is outer for gate frame is installed, the 5th step surface arranges screw thread outward, and the nylon nut with threaded engagement is set on the 5th step surface.
As preferred version of the present utility model, one L shaped oiling passage is set in described main shaft, one end of oiling passage is arranged on the place, axle center in main shaft left side, oil nozzle is installed at the place, axle center in main shaft left side, oil nozzle is communicated with one end of oiling passage, and the other end of described oiling passage is communicated with the edge of the 3rd step surface.Oil nozzle 4 grease ups are installed, are improved the rotation flexibility ratio of roller.
For improving the abrasion resistance of roller and the life-span of gate integral body, the external surface of described overcoat is coated with weldering 3-5mm wear-resistant alloy layer.
Compared with prior art, the utility model can reduce replacing roll wheel assembly to a greater extent, gives the operation of valve system safety and steady, extends its application life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, in illustrative examples and the explanation of this utility model, is used for explaining the utility model, but not as to restriction of the present utility model.
As Fig. 1, a kind of electric liquid gate roll wheel assembly shown in Fig. 2, comprise main shaft 1, the outer First terrace 11 that sets gradually vertically from right to left of described main shaft 1, second step face 12, the 3rd step surface 13, the 4th step surface 14 and the 5th step surface 15, the outer sheathed overcoat 2 of second step face 12 and the 3rd step surface 13, overcoat 2 is reducer socket, overcoat 2 is matched in clearance with second step face 12 and the 3rd step surface 13, the 4th step surface 14 is outer for gate frame 5 is installed, the outer screw thread that arranges of the 5th step surface 15, nylon nut 3 with threaded engagement is set on the 5th step surface 15.
The interior L shaped oiling passage 7 that arranges of described main shaft 1, one end of oiling passage 7 is arranged on the place, axle center in main shaft 1 left side, oil nozzle 4 is installed at the place, axle center in main shaft 1 left side, and oil nozzle 4 is communicated with one end of oiling passage 7, and the other end of described oiling passage 7 is communicated with the edge of the 3rd step surface 13.
Further, the external surface of overcoat 2 is coated with weldering 5mm wear-resistant alloy layer 8, improves the abrasion resistance of roller and the life-span of gate integral body.
During making, first step surface 11 is processed into square, to facilitate pincers tightly to unload nylon nut 3; Second step face 12 and the 3rd step surface 13 are to be processed into circularly with restriction overcoat 2, with the cooperation of overcoat 2 internal diameters, are that large matched in clearance is with free rotation; The 4th step surface is to be processed into circle to put into gate frame 5, and shaft shoulder height is enough to improve stability and the weight capacity of roll wheel assembly mounting structure; The 5th step surface is processed with screw thread tightly to unload nylon nut 3, has one " L " shape oiling passage 7 so that oil nozzle 4 grease ups to be installed in main shaft 1, improves the rotation flexibility ratio of roller.
As shown in Figure 2, the 4th step surface of the main shaft 1 of roll wheel assembly is put into gate frame 5, after nylon nut 3 is tightened.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
