Abstract
A steel raising transmission machine effectively prevents the fracture includes a motor, a drive shaft, a drive shaft, a frame, the motor and the drive shaft which is vice connected with the drive pulley. The drive shaft and the sprocket drive are vice connected by the sprocket wheel. The drive shaft is active connected with the housing, and the seat of the bearing is fixed on the frame. The machine is characterized in that a hole is arranged in the bracket, and the location of the hole is corresponding to the location of the sprocket of the drive shaft.
Description
Technical field:
The utility model relates to the driving mechanism of the steel-wire napper of frame industry, particularly steel-wire napper.
Background technique:
The driving mechanism of existing steel-wire napper contains motor, transmission shaft, live axle, support, motor is connected by the belt pulley transmission with transmission shaft, and transmission shaft is connected by sprocket driving is secondary with live axle, and motor is fixed on the support, transmission shaft and bearing support flexibly connect, and bearing support is fixed on the support.Because the chain on the sprocket driving pair is loosely to be connected on two sprocket wheels, so when motor stopped operating, transmission shaft stopped operating, drive sprocket also stops operating, but under action of inertia, driven sprocket still can rotate with inertia, therefore, chain just is stuck between drive sprocket and the fixed support easily, transmission shaft is squeezed to the outside of support push away, and causes the bearing support fracture.
The model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of steel-wire napper driving mechanism that can effectively prevent the bearing support fracture is provided.
Solution of the present utility model is: contain motor, transmission shaft, live axle, support, motor is connected by the belt pulley transmission with transmission shaft, transmission shaft is connected by sprocket driving is secondary with live axle, transmission shaft and bearing support flexibly connect, bearing support is fixed on the support, be provided with the hole on support, the position in hole is corresponding with the chain wheel location on the transmission shaft.
Since with transmission shaft on the fixed support of drive sprocket corresponding position on be provided with the hole; when motor stops operating; driven sprocket is under action of inertia; when still rotating with inertia; chain will directly enter in the hole on the fixed support; transmission shaft is pushed away by the crowded of chain no longer, thereby the protection bearing support no longer is subjected to squeeze the effect of thrust laterally and produces fracture.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the utility model embodiment's an A-A sectional drawing.
Among the figure: the 1--drive pulley; The 2--output shaft; The 3--motor; 4--is by movable sprocket; The 5--bearing support; The 6--live axle; The 7--frame; The 8--support; The 9--drive sprocket; The 10--hole; The 11--bearing support; The 12--transmission shaft; The 13--bearing support; The 14--negative pulley wheel.
Embodiment:
Below embodiment of the present utility model is described in detail:
Fig. 1 is the utility model embodiment's a structural representation.Among Fig. 1.Contain motor 3; transmission shaft 12; live axle 6; support 8; motor 3 is fixedly mounted on the top of support 8; fixedly mounted the drive pulley 1 of belt pulley transmission on the output shaft 2 of motor 3; the negative pulley wheel 14 of belt pulley transmission is fixedly mounted on an end of transmission shaft 12; the other end of transmission shaft 12 has fixedly mounted the drive sprocket 9 of sprocket driving pair; transmission shaft 12 and bearing support 11; 13 flexibly connect; bearing support 11; 13 are fixedly mounted on the side of support 8; on the side of support 8, be provided with hole 10; the position in hole 10 is corresponding with the position of the drive sprocket 9 of sprocket driving pair; guarantee to stop operating at motor 3; when under action of inertia, still being rotated with inertia by movable sprocket 4; chain can directly enter in the hole 10 on the support 8; transmission shaft 12 is pushed away by the crowded of chain no longer; thereby protection bearing support 11; 13 no longer are subjected to crowded the pushing away of chain and produce fracture; being fixedly mounted on the live axle 6 of sprocket driving pair by movable sprocket 4; live axle 6 flexibly connects with bearing support 5; bearing support 5 is fixedly mounted on the frame 7, and support 8 is fixedly connected on the frame 7.
Fig. 2 is the utility model embodiment's an A-A sectional drawing.Among Fig. 2, the hole 10 on the support 8 is represented more clearly with the relative position of drive sprocket 9.
