Abstract
The utility model discloses a paper-conveying transmission speed change mechanism which comprises a box body, an input shaft, an output shaft and an output gear, wherein the input end and the output end are arranged on the box body, and the output gear is arranged on the output shaft. A middle gear matched with an input gear and the output gear is arranged between the input gear and the output gear through connecting rods. When the paper-conveying transmission speed change mechanism is operated, the middle gear is accelerated or decelerated and swings along with the cycle of the output gear under the effect of a first connecting rod and revolves around the output gear, the aim that the output gear is cyclically accelerated or decelerated is achieved, and the input gear which is eccentrically installed is convenient to manufacture. The paper-conveying transmission speed change mechanism is simple, compact and reasonable in structure, the complete set of speed change mechanism is arranged inside the box body with strong rigidity, the paper-conveying transmission speed change mechanism is stable in operation at a high speed, and accuracy and stability when paper is conveyed at the high speed are ensured. Due to the fact that the box body is of a closed type, noise is low, lubricating oil can also not be wasted or pollute the working environment due to splashing of the lubricating oil. Due to the fact that vibration attenuation damping devices which are multiply overlapped are not required, the working temperature of the mechanism is low, unnecessary energy consumption is reduced, and the paper-conveying transmission speed change mechanism saves more energy..
Description
Technical field
The utility model relates to defeated paper transmission shifting mechanism.
Background technique
For before guaranteeing the high speed paper guide paper arriving in defeated paper process during rule accurately and steadily, must adopt the defeated paper of speed change, namely under the constant situation of mean velocity, the initial speed of paper operation is higher than average degree, speed before arriving during rule is lower than mean velocity (linear velocity generally is advisable with interior 0.6 meter of per second), otherwise the speed of rule was fast before paper arrived, bounce-back during rule before the thick paper impacts, thin paper are easily Texturized, cause the inaccurate situation that maybe can't locate in paper location.
1. patent No. ZL 200620101593.1 is a kind of fourbar linkage and eccentric input Gear combination gear, as Fig. 1, Fig. 2, it is by input hinge connecting rod and output hinge connecting rod eccentric position place gear, coupling shaft and gear, output shaft and gear to be connected together, constitute two epicyclic gear trains, thereby reach the purpose of the defeated paper of cycle speed change.But the defective of this mechanism is; The one, its input, output hinge connecting rod are that single armed connects, the 2nd, this mechanism is installed on the input and output axle with cantilevered fashion, so when failing paper at a high speed, can produce vibration, paper feed speed also is subjected to certain difficult system, the 3rd, the deceleration rate of this mechanism has only 26%, so this structure can't satisfy the requirement of at a high speed defeated paper.In addition, the speed of this structure output speed and paper guide transport roller does not match, and must increase the corresponding part that changes velocity ratio, and required rotating speed is passed to transport roller.
2. patent No. ZL 2,009 2 0112936.8 is a kind of deformed elliptic gear speed change mechanism, and as Fig. 3, it is to realize speed change by the transmission that one group of off-centre is installed in the deformed elliptic gear on the input shaft and is installed in the indicatrix ellipse tooth on the transmission shaft.The scarce limit of this mechanism is; Because the gyration center of these two gears departs from barycenter, such gear is processing difficulties not only, and low precision, meshing backlass is big, adds that the acceleration of variable motion generation is useless, produces bigger impact when causing running, mechanical vibration and noise are big, so at input shaft and flywheel shaft one group of the 3rd deformed elliptic gear and the 4th deformed elliptic gear and inertial flywheel have been installed again, have been eliminated mechanical vibration and caused speed fluctuation.Other part damping block, dynamic damping dish, damping friction plate, spring, damped flywheel, bolt, clamping disk(-sc), all be for mechanical vibration, speed fluctuation, the transmission impulse inertia of eliminating this mechanism again set, consumed bigger energy again, installation difficulty is big, manufacture cost is high, be not arranged on vibration and impulse source because of this this weakening and damping device again, although so organizational overlapping, effect is not fine.
