Abstract
The utility model discloses a coupling mechanism of lever and axle, including lever and hollow shaft, the lever left side is circular, and inside opening has a hollow shaft hole, and the hollow shaft passes hollow shaft hole device on the bearing frame of lever below, the centre of lever is equipped with a horizontally gap groove, on the lever for the each side in hollow shaft hole be equipped with one take the tooth to the trompil, on the bolt passes and fixes on the lever to the trompil with the fastening of hollow axle clamp, the below of bearing frame is connected with carries out the piece, running from opposite directions downthehole tooth and setting up for radial symmetry, the quantity of tooth has at least a pair ofly. The utility model discloses a connection structure is simple, and manufacturing procedure is simple, has practiced thrift processing material and processing cost, the rotating actuator of specially adapted hollow shaft.
Description
Technical field
The utility model relates to a kind of bindiny mechanism, particularly relates to the bindiny mechanism of a kind of lever and axle.
Background technique
The anatomical connectivity of lever and axle is for the connection of rotary air heater, and heating device is used for improving the wind-warm syndrome entering air preheater, prevents low-temperature corrosion of air preheater and stifled ash.Heating device is arranged between gas fan outlet and air preheater entrance, what the connection of lever and axle adopted usually is that the method such as keyway or spline connects, this Placement makes the linkage structure of workpiece complicated, processing difficulties, particularly hollow shaft, need to increase pipe thickness, solve keyway problem, therefore bring the problem of cost of material and processing charges increase.
Model utility content
In order to solve the deficiency existing for above-mentioned technology, the utility model provides the bindiny mechanism of a kind of lever and axle.
In order to solve above technical problem, the technical solution adopted in the utility model is: the bindiny mechanism of a kind of lever and axle, comprises lever and hollow shaft, is circular on the left of lever, inside has a hollow axis hole, and hollow shaft is through on the bearing support of hollow shaft aperture apparatus below lever; The centre of lever is provided with the clearance groove of a level; On lever relative to hollow axis hole be each side provided with a band tooth to perforate, bolt is through being fixedly clamped to perforate on lever by hollow shaft; The below of bearing support is connected with actuator; To the tooth in perforate be radial symmetric arrange, the quantity of tooth has a pair at least.
The length of clearance groove accounts for 3/4ths of whole lever length from left to right.
Lever diminishing to turning right gradually along horizontal centre line width perforate from right side, the low order end of lever offers circular hole.
Linkage structure of the present utility model is simple, and manufacturing procedure is simple, has saved rapidoprint and processing cost, has been specially adapted to the rotating actuator of hollow shaft.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the plan view of Fig. 1.
In figure: 1, lever; 2, hollow shaft; 3, bolt; 4, bearing support; 5, actuator; 6, mesopore; 7, circular hole.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises lever 1 and hollow shaft 2, and be circular on the left of lever 1, inside has a hollow axis hole, and hollow shaft 2 is through on the bearing support 4 of hollow shaft aperture apparatus below lever 1; The centre of lever 1 is provided with the clearance groove 6 of a level; On lever 1 relative to hollow axis hole be each side provided with a band tooth to perforate, bolt 3 is through being fixedly clamped to perforate on lever 1 by hollow shaft 2; Be provided with tooth in perforate, can tightly bite middle bolt shank in the middle of connecting, play the effect that a fastening strengthening stud connects, by the length of swivel bolt cap adjustment bolt shank at clearance groove 6, play and strengthen the fixing effect of hollow shaft 2; The below of bearing support 4 is connected with actuator 5; Be the snap-in force of radial symmetric setting, increase tooth to the tooth in perforate, and the quantity of tooth have a pair at least, is generally designed to three pairs of snap-in forces the strongest.
The length of clearance groove 6 accounts for 3/4ths of whole lever 1 length from left to right, and the design of clearance groove 6 can make lever have slight deformation in the middle of clearance groove 6, more firm when bolt 3 adjustment is installed.
Lever 1 diminishing to turning right gradually along horizontal centre line width perforate from right side, the low order end of lever 1 offers circular hole 7.Circular hole 7 can facilitate leverage driving mechanism or other assemblys, when lever 1 has running torque, drives hollow shaft 2 to rotate, makes hollow shaft 2, by bearing support 4, running torque be passed to actuator 5, thus drive execution corresponding actions by actuator 5.
Lever 1 is designed to the inconsistent structure of left and right size width by the utility model, and like this when lever 1 is subject to same rotating force, the lever running torque consistent compared with left and right width is larger, more laborsaving.
Above-mentioned mode of execution is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
