Description
Technical Field
The utility model belongs to spandex polymerization equipment field, concretely relates to reactor bearing positioner.
Background
Currently, in the spinning apparatus, the bearing of the second reactor for continuously spinning spandex (the second reactor is used for reacting prepolymer and chain extender) is fixed on a bearing seat, and in order to make the shaft and the bearing on the same axis as much as possible, a positioning hole needs to be drilled on the shaft and fixed inside the bearing through a jackscrew (a modified second reactor bearing 201820252000.4). The positioning of the shaft is mainly dependent on positioning by changing the relative position of the large bearing of the reactor and the main shaft. This has the following disadvantages: firstly, when a new shaft is positioned for the first time, positioning holes are required to be punched (the main shaft and a large bearing are prevented from generating relative displacement to cause abrasion and axial movement), the positioning holes play a role in positioning and connecting the bearings, the requirement on operators is high, and the control precision of the positioning size is low; secondly, after the positioning hole is used for multiple times, the positioning hole is deformed, the positioning size has larger deviation, and the positioning hole needs to be polished again, even the positioning hole needs to be punched again; thirdly, the positioning holes also need to be re-drilled due to errors in assembly and different sizes of the fittings.
Disclosure of Invention
The to-be-solved technical problem of the utility model lies in providing a reactor bearing positioner who changes in location.
The utility model discloses a realize like this:
the utility model provides a reactor bearing positioner, includes the axle, is used for the bearing of back shaft, is used for supporting bearing's bearing frame and gasket, the bearing with the bearing frame is for dismantling the connection, gasket detachably set up in the bearing frame with between the bearing.
Furthermore, a jackscrew hole is formed in the shaft and is connected with the bearing through the jackscrew, so that the connecting position of the bearing and the shaft is fixed.
Further, the bearing is connected with the bearing seat through a bolt.
Further, the gasket is composed of a base gasket and an adjusting gasket, and the base gasket is preset between the bearing seat and the bearing.
Furthermore, the adjusting shim is composed of a plurality of shims with the same or different thickness specifications.
Still further, the gasket is a rubber gasket.
The utility model has the advantages that: through with bearing and main shaft hookup location fixed, add the shim and adjust the location size in the middle of rethread bearing and the bearing base, the operation is simpler and easy during the location, and the location size is changeed in control and regulation.
Drawings
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the reactor bearing positioning device of the present invention includes a shaft 1, a bearing 2 for supporting the shaft 1, a bearing seat 3 for supporting the bearing 2, and a gasket 4, wherein the gasket 4 is detachably disposed between the bearing seat 3 and the bearing 2.
In order to fix the relative position of the shaft 1 and the bearing 2, a jackscrew hole is arranged on the shaft 1, the bearing 2 is connected through a jackscrew 5, and the connecting position of the bearing 2 and the shaft 1 is fixed. The jackscrew hole only plays a connecting role, accurate positioning is not needed, and the requirement on operators is low.
The bearing 2 is connected with the bearing seat 3 through a bolt 6.
The shim 4 is composed of a base shim 41 and an adjusting shim 42, wherein the base shim 41 is preset between the bearing seat 3 and the bearing 2 (opposite surfaces of two sides of the base shim 41 are respectively contacted with the bearing seat 3 and the bearing 2). The adjusting shim 42 is composed of a plurality of shims with the same or different thickness specifications. For example, a 2.50mm (as appropriate depending on the actual situation) spacer is used as the base spacer 41, the base spacer 41 is preset in the bearing housing 3, then the coupling position of the main shaft 1 and the large bearing 2 is determined, and a screw hole is punched to fix the coupling position of the large bearing 2 and the main shaft 1. Finally, the positioning size is measured, the adjusting shim 42 is used for adjusting (realized by the superposition of shims), and the bearing 2 and the bearing seat 3 are fixedly connected through 4 bolts 6 after the adjustment. The gasket can be processed into the following dimensions: 0.30mm, 0.50mm, 1.00mm, 2.50mm (thickness of the shim). Examples of the adjustment are: -0.10mm (0.3+0.3+0.3+1+ 0.5); -0.20mm (0.3+0.5+0.5+ 1); -0.30mm (0.3+0.3+0.3+0.3+ 1); +0.10mm (1+1+0.3+0.3) etc (+, -indicates a different direction, i.e. the bearing 2 forward and backward movement direction). The adjustment range meets the positioning size deviation.
By changing the adjusting shim 42, the positioning size change caused by abrasion deformation and accessory size change can be eliminated on the premise that the relative position of the large bearing 2 and the main shaft 1 is not changed. The trouble that the positioning hole needs to be punched again is avoided, the operation is more convenient, the positioning can be completed only by measuring and then simply calculating. The positioning dimension is also well stabilized within a certain value (controlled by varying the thickness of the spacer).
Although specific embodiments of the present invention have been described, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the claims appended hereto.
