Abstract
The invention discloses a conveniently-assembled combined shaft which is characterized in that a transmission shaft and a coupling shaft which are arranged at two ends and an intermediate shaft located between the transmission shaft and the coupling shaft are connected through a shaft end key groove, a subdivision-type shaft sleeve and a bolt respectively to form an whole, and a workpiece is arranged on the intermediate shaft. When a working part on the shaft is disassembled, only the connection bolt of the subdivision-type shaft sleeve needs disassembling, and the middle section of the shaft is taken out from the key groove to conveniently assemble and disassemble the working part on the shaft. The conveniently-assembled combined shaft is simple in structure and convenient and rapid in use when the workpiece on the shaft needs disassembling and assembling frequently, the unnecessary disassembly and assembly of other parts are reduced, the work efficiency is improved, and the service life of a machine is prolonged.
Description
Technical field
The present invention relates to a kind of removable built-up shaft, belong to the manufacturing technology field of mechanical processing industry.
Background technique
In the prior art, the axle in the machinery all is a bearing, and as shown in Figure 1, the installation of bearing A normally is fixed on the two ends of bearing A among the casing F by radial bearing B.In this structural type, when removing the workpiece 06 on the bearing A, need to remove first end driving component D, remove again bearing gland C, bearing A is extracted out from casing together with radial bearing B; In taking out the process of axle, need workpiece 06 is slowly withdrawed from.The shortcoming of doing like this is: the workload of dismounting is large, needs larger space, sometimes interferes with the adjacent zeros parts, also needs to remove the component of mutual interference, just can finish the dismounting of workpiece 06 on the axle.
For some machinery, workpiece is easily damaged parts on the axle, and the disassembly process of its frequent must increase workload, and excessive dismounting, also can increase the damage to equipment.
Summary of the invention
The present invention is for avoiding the existing deficiency of above-mentioned prior art, and a kind of built-up shaft of simple in structure, efficiently convenient dismounting of dismounting is provided, increasing work efficiency, to reduce unnecessary dismounting, and extension device working life.
The present invention is that the technical solution problem adopts following technological scheme:
The built-up shaft of the convenient dismounting of the present invention, its structural feature is: by as a whole by axle head keyway, split type axle sleeve and Bolt Connection respectively at the transmission shaft at two ends and joining shaft and the jack shaft between transmission shaft and joining shaft, workpiece is installed on the described jack shaft.
The built-up shaft of the convenient dismounting of the present invention, its structural feature also is:
The two ends of described jack shaft are processed with the key of projection, and the transmission shaft and the joining shaft that cooperate with described jack shaft are processed with keyway at axle head, with key and the keyway transition fit of projection.
Be provided with described split-type shaft at described jack shaft, transmission shaft and joining shaft and put the corresponding through hole in bolt hole position.
Keyway and the split type axle sleeve of the present invention by axle head eliminated radial displacement in the axle connection process, by putting the brill matching hole at axle and split-type shaft, and is fixed by bolt, eliminates moving axially of axle; The elimination of the radial and axial movement between joining shaft has guaranteed the rigidity requirement in the course of the work of transmission shaft, jack shaft and joining shaft.
Compare with existing technology, the effect that the present invention is useful is embodied in:
1, the present invention is simple in structure, and is convenient to disassembly, increases work efficiency.
2, the present invention reduces the unnecessary dismounting of other parts, improves the working life of machine.
Description of drawings:
Fig. 1 is the mounting type schematic diagram of bearing in the prior art;
Fig. 2 is structural representation of the present invention.
Number in the figure: A bearing, B radial bearing, C bearing gland, D driving component, F casing; 01 transmission shaft, 02 jack shaft, 03 joining shaft, 04 split type axle sleeve, 05 attachment bolt, 06 workpiece.
Embodiment
Referring to Fig. 2, the built-up shaft of convenient dismounting is as a whole by connecting by axle head keyway, split type axle sleeve 04 and bolt 05 respectively at the transmission shaft 01 at two ends and joining shaft 03 and the jack shaft 02 between transmission shaft 01 and joining shaft 03 in the present embodiment, and workpiece 06 is installed on the jack shaft 02.
In the implementation, the two ends of jack shaft 02 are processed with the key of projection, and the transmission shaft 01 that cooperates with jack shaft 02 and joining shaft 03 are processed with keyway at axle head, with key and the keyway transition fit of projection; Be provided with and the corresponding through hole in split type axle sleeve 04 upper bolt hole position at jack shaft 02, transmission shaft 01 and joining shaft 03, namely be drilled with the through hole vertical with keyway at jack shaft 02 with the end that cooperatively interacts of transmission shaft 01 and joining shaft 03, put at split-type shaft accordingly and be drilled with two through holes vertical with cutting plane.
The present embodiment is used for steel-plate washing machine, and workpiece 06 is polishing wheel or cleans the hair roller.
When removing on the jack shaft 02 workpiece 06, unclamp first and remove attachment bolt 05, take off split type axle sleeve 04, just can easily jack shaft 02 be shifted out from the keyway of transmission shaft 01 and joining shaft 03, then dismantle the workpiece 06 on the jack shaft 02.
When workpiece 06 is installed on the jack shaft 02, first workpiece 06 is installed on the jack shaft 02, again jack shaft 01 is assembled in the keyway of transmission shaft 01 and joining shaft 03, split type axle sleeve 04 closes, attachment bolt 05 is passed hole on split type axle sleeve 04, jack shaft 02, transmission shaft 01 and the joining shaft 03, and locking nut is installation.
