Abstract
The invention relates to a pull type chain wheel automatic adjusting device, which can automatically adjust the position of a tension wheel in the use process of a ball chain transmission device, and comprises a rack, a support, a chain wheel support and a tension chain wheel, wherein the support is arranged on the rack, the chain wheel support is arranged on the support through an adjusting bolt, an adjusting nut and a locking nut, the tension chain wheel is arranged on the chain wheel support through a chain shaft, and the support is arranged at one side of the tension chain wheel, opposite to the action direction of the ball chain. The pull type chain wheel automatic adjusting device also comprises a compression spring automatic adjusting structure. During the use process of the ball chain transmission device, if the ball chain is worn to be stretched, the tension wheel can be automatically outwards pulled through the compression ring, so that the pretightening force of the ball chain can be maintained in a certain range.
Description
Technical field
The present invention relates to the logistics conveying equipment, be specially pull-type sprocket wheel automatic control tegulatingdevice.
Background technique
Use the ball chain transmission device on the logistics conveying equipment widely; Its structure such as Fig. 1; Shown in Figure 2, it comprises frame 1, support 2, and support 2 is installed on the frame 1 in the identical side of ball chain 5 force directions through fixing bolt 11 and set screw nut 12; Chain wheel support 4 is installed on the support 2 through regulating bolt 8, locking nut 10, adjusting nut 3 and tightening nut 9, and tension sprocket 7 is installed on the chain wheel support 4 through sprocket shaft 6.Generally, its tension sprocket 7 is taked to come adjusted position from the interior mode on top outward, makes ball chain 5 keep certain pretightening force.In use, because of wearing and tearing, ball chain can be extended, and so just usually need adjust tension sprocket 7, has increased a lot of plant maintenance workloads, and can shorten life of equipment.
Summary of the invention
To the problems referred to above, the invention provides pull-type sprocket wheel automatic control tegulatingdevice, after assembling and setting finishes first, no longer need adjust the position of sprocket wheel, regulate automatically by self-regulation structure.Pretightening force maintains in certain scope, and is reliable and stable, reduced the maintenance workload to equipment, reduced the wear extent of sprocket wheel and chain, can make equipment that arranged long working life.
Its concrete technological scheme is such: pull-type sprocket wheel automatic control tegulatingdevice; It comprises frame, support, chain wheel support, tension sprocket; Described support is installed on the described frame; Described chain wheel support is installed on the described support through regulating bolt, adjusting nut and locking nut; Described tension sprocket is installed on the described chain wheel support through sprocket shaft, it is characterized in that: it also comprises the stage clip self-regulation structure, described support be installed in said tension sprocket on the opposite side of ball chain force direction.
It is further characterized in that: described stage clip self-regulation structure comprises stage clip, and described compression spring sleeve is loaded on the described adjusting bolt and is positioned in the middle of support and the adjusting nut, and described stage clip two ends are respectively arranged with rounded washers; Described adjusting bolt and described chain wheel support are weldingly connected; Have spacing long lumbar hole on the described support, an end of described sprocket shaft inserts in the described spacing long lumbar hole.
The present invention adopts said structure, after debugging assembles first, in use; Stage clip can be pulled outwardly tension sprocket when ball chain is because of the wearing and tearing elongation automatically; The pretightening force of ball chain is maintained in certain scope, reliable and stable, reduced maintenance workload to equipment; Reduce the wear extent of sprocket wheel and chain, prolonged the working life of mechanism.Sprocket shaft one end inserts in the oval hole on the frame, guarantees that sprocket wheel can not rotate when mobile, prevents that sprocket wheel from " eating the limit " and wrong engagement.

Embodiment
Like Fig. 3; Fig. 4 the present invention includes frame 1, support 2, chain wheel support 4, tension sprocket 7, and support 2 is installed on the frame 1; Chain wheel support 4 is installed on the support 2 through regulating bolt 8, adjusting nut 3 and locking nut 10; Tension sprocket 7 is installed on the chain wheel support 4 through sprocket shaft 6, and it also comprises the stage clip automatic control tegulatingdevice, and support 2 is installed in and the opposite side of ball chain 5 force directions of opening on the sprocket wheel 7.The stage clip automatic control tegulatingdevice comprises stage clip 13, and stage clip 13 is set in to regulate and is positioned on the bolt 8 in the middle of support 2 and the adjusting nut 3, and stage clip 13 two ends are respectively arranged with rounded washers 14 and 15; Regulating bolt 8 is weldingly connected with chain wheel support 4; Have spacing long lumbar hole 16 on the support 2, an end of sprocket shaft 6 inserts in the spacing long lumbar hole 16.Fig. 1 is existing chain gear apparatus plan view, and Fig. 2 is existing chain gear apparatus plan view.11 is fixing bolts among Fig. 1 to Fig. 4, the 12nd, and set screw nut.17 is solder joints among Fig. 4.
In the using process of ball chain transmission device, stage clip 13 can be pulled outwardly tension sprocket 7 when ball chain 5 is because of the wearing and tearing elongation automatically, and the pretightening force of ball chain 5 is maintained in certain scope, and is reliable and stable, reduced the maintenance workload to equipment.
