Abstract
The utility model relates to a speed reducer device with a roller convenient to replace. The speed reducer device comprises a speed reducer fixing seat, a slide sleeve coupler and a speed reducer shaft and is connected with the roller; the slide sleeve coupler is arranged at the inner side of the speed reducer fixing seat and is composed of upper and lower parts which are axially symmetrical; when the two parts are tensioned and connected with each other by screws, the slide sleeve coupler is connected with a shaft of the roller; when the screws on the slide sleeve coupler are loosened, the slide sleeve coupler slides on the shaft of the roller and the roller is separated from a speed reducer. Compared with the prior art, the speed reducer device has the advantages of small labor intensity, high replacing efficiency, simplicity in operation and the like; in a roller detaching process, the speed reducer does not need to be demounted and only the screws need to be loosened or tightened, so that the labor intensity is greatly reduced; all detachable parts, which need to be accurately positioned, are provided with positioning pins and thus secondary adjustment on positioning precision is not needed.
Description
Technical field
The utility model relates to a kind of reductor, especially relates to a kind of speed reducer device that is convenient for changing roller.
Background technology
At present, when plastic sheets is made, a lot of plastic plate product surfaces all need to suppress decorative pattern, and decorative pattern pattern may need frequent replacing, but for guaranteeing the rotation precision of roller, substantially adopting the directly connected mode of socket between roller and reductor, is minimum matched in clearance between roller shaft and reductor, the most difficult while changing roller is by reductor and roller disengaging, the situation that while even occurring extracting reductor, reducer shell is opened by drawing crack.Waste time and energy, may also can follow larger economic loss.
Application number is disclosing of 200910069652.X is provided with the two-roll calendar of interchangeable sleeve, mainly comprise frame, liftable roller, interchangeable sleeve roller, roller drive motors, cut rubber roll, cut rubber roll drive motors, trimming device, roll-setting gear and bascule, wherein the roller of interchangeable sleeve is comprised of core roller and sleeve.Can make sleeve on the roller of interchangeable sleeve on it and core roller when assembling activity fit clearance between the two because of the former of Action of Gravity Field thereby all concentrate on sleeve and the minimum point of core roller vertical lower, and its gap of going up point is most zero, can make like this to adjust interval work quantitative change between liftable roller and the roller of interchangeable sleeve and obtain directly with convenient and swift, and the thickness of film and dimensionally stable.But this calender, when dismounting roller, still will depart from reductor and roller, therefore exists and uses inconvenience, easily damages mechanical shortcoming.
Utility model content
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of labour intensity little, change high, the simple to operate speed reducer device that is convenient for changing roller of efficiency.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of speed reducer device that is convenient for changing roller, comprise reductor holder, sliding sleeve shaft coupling, reductor shaft, speed reducer device is connected with roller, described sliding sleeve shaft coupling is located at the inner side of reductor holder, by two parts up and down that are axial symmetry, formed, between two parts, through screw tension, connect, sliding sleeve shaft coupling is connected with the axle of roller, unclamp screw on sliding sleeve shaft coupling and sliding sleeve shaft coupling is slided on the axle of roller make roller and reductor disengaging.
Described sliding sleeve shaft coupling has the positioning spigot that carries out quick location and installation with reductor shaft near reductor end.
Described roller is connected with reductor holder through roller bearing seats.
Described roller bearing seats is comprised of two parts up and down of axial symmetry, connects and be provided with the alignment pin of maintenance connection precision between upper and lower two parts through screw.
Described reductor holder is comprised of two parts up and down of axial symmetry, is connected respectively through screw with the roller bearing seats coupling being comprised of upper and lower two parts.
The latter half of described reductor holder guarantees the concentricity between reductor and bearing block through the latter half location of alignment pin and roller bearing seats.
The original output hollow shaft of described reductor shaft and reductor is fixed, and is provided with the positioning boss matching with sliding sleeve shaft coupling positioning spigot at the link with roller.
Compared with prior art, the utlity model has following advantage:
Labour intensity is little: in dismounting roller process, do not need to remove reductor again, only need to unclamp or tighten the screws, greatly reduced labour intensity.
Replacing efficiency is high: the pinpoint part of all detachable needs, with alignment pin, does not need secondary to regulate positioning precision, has improved the efficiency of changing.
Simple to operate: whole dismounting and installation process only need a set of inner hexagon spanner and screwdriver.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is roller bearing seats, and 2 is reductor holder top, and 3 is reinforcement protection plate, and 4 is sliding sleeve shaft coupling screw, and 5 is attachment screw, and 6 is sliding sleeve shaft coupling, and 7 is reductor holder bottom, and 8 is reductor shaft.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
Be convenient for changing a speed reducer device for roller, its structure as shown in Figure 1, comprises the assemblies such as reductor holder, sliding sleeve shaft coupling, reductor shaft, and speed reducer device is connected with roller.Sliding sleeve shaft coupling 6 is located at the inner side of reductor holder, through attachment screw 5, connects, and sliding sleeve shaft coupling 6 is located between reductor holder can also arrange reinforcement protection plate 3.Sliding sleeve shaft coupling 6 consists of two parts up and down that are axial symmetry, between two parts, through 4 tensions of sliding sleeve shaft coupling screw, connect, sliding sleeve shaft coupling 6 is connected with the axle of roller, unclamps sliding sleeve shaft coupling screw 4 on sliding sleeve shaft coupling 6 and sliding sleeve shaft coupling 6 is slided on the axle of roller roller and reductor are departed from.
Roller is connected with reductor holder through roller bearing seats 1.Roller bearing seats is comprised of two parts up and down of axial symmetry, connects and be provided with the alignment pin of maintenance connection precision between upper and lower two parts through screw.Reductor holder is comprised of reductor holder top 2,7 two of the reductor holder bottoms part of axial symmetry, is connected respectively through screw with the roller bearing seats coupling being comprised of upper and lower two parts.Wherein, the latter half of reductor holder Lower Half 7 lease making alignment pins and roller bearing seats location guarantees the concentricity between reductor and bearing block.
