Adopt the utility model discloses a connection structure can make the transmission shaft with be detachable connection between the reel, the convenience is maintained and is changed, conveniently improves the intensity of transmission shaft, makes things convenient for the machine tooling to make cost and operating time reduce.
Description
Technical field
This utility model relates to sleeve type spool shaft, particularly relates to a kind of sleeve type spool shaft on crane.
Background technology
In existing crane, being connected by decelerator and power transmission shaft between its reel with electromotor, described power transmission shaft is connected with the end face of described reel by welding, and the power transmission shaft that rotates through of electromotor is delivered to reel.Such set-up mode has a following drawback: 1. be welded to connect owing to using between power transmission shaft and reel, be difficult to change after power transmission shaft or reel damage；2., in order to ensure welding effect, the steel that power transmission shaft is used must be for below 35#, and intensity is relatively low；To use the steel of high intensity, then can not reach welding effect；3. use the mode of welding, first power transmission shaft must first be welded with reel, then be machined out, processing inconvenience, must expend more cost of labor and working time.
Utility model content
The purpose of this utility model is to provide the attachment structure of a kind of sleeve type spool shaft using high strength driving shaft.
To achieve these goals, this utility model is achieved in that the attachment structure of a kind of sleeve type spool shaft for crane, including reel and with the power transmission shaft of described reel axial restraint, also include reel flange, described reel flange includes that inwall is provided with the axis hole of spline and is arranged on the ring flange of described axis hole outer wall, described ring flange is connected by screw is fixing with the end face of described reel, and one end of described power transmission shaft is connected with described axis hole spline.Use such structure, in advance transmission can be carried out axle machining, the power transmission shaft processed is connected with described reel flange spline, again reel flange is connected with the end face screw of described reel, so structure of sleeve type enables to can be convenient for changing when damaging at reel or power transmission shaft, it additionally is able to so that described power transmission shaft can use the steel of higher intensity, it is ensured that the transmission of power.
In order to be further ensured that the transmission of power, being provided with the baffle plate of endoporus more than described axis hole in one end of described axis hole, described baffle plate is connected with the end face of described power transmission shaft by screw.Such setting can carry out axial restraint to described power transmission shaft, it is to avoid described power transmission shaft occurs play in the axial direction, it is ensured that the transmission of power.
In order to further such that manufacture simplicity, described baffle plate and described reel flange are split type setting.
In order to increase the intensity of described reel flange further, between the outer wall and described ring flange of described axis hole, it is provided with reinforcement.
Preferably, described reinforcement is polylith and the same side being arranged on described ring flange.
Use the attachment structure of sleeve type spool shaft described in the utility model, have the advantages that 1. convenient disassemblies, by existing reel and power transmission shaft be welded to connect the spline changing using reel flange into and screw connects, make to be connected for dismountable between reel with power transmission shaft, convenient maintenance and replacing；2. intensity is high, and the spline using transmission moment of torsion good between described power transmission shaft with described reel flange is connected, enabling using the steel of high intensity to make power transmission shaft, being additionally provided with reinforcement on described reel flange can increase intensity；Low cost the most easy to process, uses attachment structure of the present utility model can be machined out power transmission shaft in advance to process convenient low cost.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model embodiment.
Label declaration: 1. reel；2. power transmission shaft；3. reel flange；31. axis holes；32. ring flanges；33. reinforcements；4. baffle plate.
Detailed description of the invention
This utility model will be introduced below by the embodiment shown in accompanying drawing; but this utility model is not limited to introduced embodiment; any improvement on the present embodiment essence spirit or replacement, still fall within this utility model claim scope required for protection:
Embodiment: as shown in Figure 1, a kind of attachment structure of the sleeve type spool shaft for crane, including reel 1 and with the power transmission shaft 2 of described reel 1 axial restraint, also include reel flange 3, described reel flange 3 includes that inwall is provided with the axis hole 31 of spline and is arranged on the ring flange 32 of described axis hole 31 outer wall, described ring flange 32 is connected by screw is fixing with the end face of described reel 1, and one end of described power transmission shaft 2 is connected with described axis hole 31 spline.
It addition, be provided with the baffle plate 4 of the endoporus more than described axis hole 31 in one end of described axis hole 31, and described baffle plate 4 is split type setting with described reel flange 3；Described baffle plate 4 is connected with the end face of described power transmission shaft 2 by screw.
It addition, be provided with reinforcement 33 between the outer wall and described ring flange 32 of described axis hole 31；Described reinforcement 33 is polylith and the same side being arranged on described ring flange 32.
In the present embodiment, described reinforcement 33 is the reinforcement of triangle, is total up to 6 pieces, is uniformly arranged between described ring flange 32 and the outer wall of described axis hole 31.
Use the attachment structure of the spool shaft of the present embodiment, first power transmission shaft 2 can be machined out when connecting, process the external splines being connected with described reel flange 3 in one end of described power transmission shaft 2, then described power transmission shaft 2 is connected with the internal spline of the axis hole 31 on described reel flange 3 with one end of spline；Subsequently described baffle plate 4 is placed in the other end of described reel flange 3, and use screw that the end face by described baffle plate 4 with described power transmission shaft 2 is connected, make the end face of described baffle plate 4 and the end contact of described reel flange 3, so described power transmission shaft 2 can be carried out axial limiting, power transmission shaft 2 is avoided to produce axial float in the course of the work, it is ensured that the transmission of power.
Use the attachment structure of the sleeve type spool shaft of the present embodiment, it is possible to make to be detachable connection between described power transmission shaft and described reel, conveniently keep in repair and change, conveniently the intensity of raising power transmission shaft, facilitate machining to make cost and working time reduction.
