Abstract
The utility model discloses a positioning sleeve of a stirring paddle. The positioning sleeve is characterized by comprising a lubricating sleeve, a fastening sleeve, a pressure releasing hole and a bolt connecting hole, wherein the lubricating sleeve and the fastening sleeve are respectively divided into two pieces from the middle; the fastening sleeve is connected by bolts through the bolt connecting holes; the pressure releasing hole is drilled at the center of the bottom surface of the fastening sleeve. The positioning sleeve disclosed by the utility model has the advantages that when the stirring paddle rotates, the swinging amplitude of the stirring paddle is limited by a gap between the lubricating sleeve and a central shaft of the stirring paddle, and pressure formed by slurry in the gap between the lubricating sleeve and the central shaft of the stirring paddle is released by the pressure releasing hole, so that the balance of internal pressure and external pressure is achieved, the jumping of the shaft is reduced, and the service lives of a groove body, a speed changing box and a bearing are prolonged; the positioning sleeve is wear-resistant, can be quickly disassembled and assembled and is convenient to replace.
Description
Technical field
The utility model relates to a kind of positioning sleeve of paddle.
Background technology
The agitating device being formed by cell body and paddle at present, paddle adopts suspension type, and stirring transmission is by driven by motor gearbox, and gearbox drives paddle to rotate.Gearbox is connected by flange with paddle, and approaching flange end has one to two bearing-transmission location.Due to location, upper end just, the paddle of growing up for the build using in industrial processes, in rotary course, amplitude of fluctuation is large, in groove, slip forms severe impact to cell body, has shortened the service life of cell body, gearbox, bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of paddle positioning sleeve, and the large shortcoming of paddle amplitude of fluctuation while overcoming paddle lower end without positioning sleeve reduces the severe impact of slip to cell body, extends the service life of cell body, gearbox, bearing.
A kind of paddle positioning sleeve, is characterized in that: comprise lubricating sleeve, adapter sleeve, relief hole and bolt connecting hole, it is two that lubricating sleeve and adapter sleeve centering are cutd open, and adapter sleeve is bolted hole bolt and connects, and adapter sleeve bottom center is drilled with relief hole.In the time that paddle rotates, the amplitude of fluctuation of paddle has been limited in the gap of lubricating sleeve and paddle axis, and the pressure that the slip in lubricating sleeve and paddle in shaft clearance forms, by relief hole pressure release, reaches interior pressure and outer pressure balanced, reduces the play of axle.
Preferably, described lubricating sleeve is selected polytetrafluoroethylene (PTFE) or polyamide fiber material, works impulsive force and the rigidity rubbing action of alleviating axle, and corrosion-resistant, adapter sleeve is selected Stainless steel 316 L material, when lubricating sleeve and adapter sleeve assembling, is tight fit, and the relief hole of φ 20 mm bores in adapter sleeve bottom center.
Preferably, lubricating sleeve coordinates with paddle axis for matched in clearance, gap 2-3mm.
Preferably, shaft end and adapter sleeve bottom surface gap 5-10mm in paddle.
The utility model has the advantages that: the one, agitating device is installed after paddle positioning sleeve, in the time that paddle rotates, the amplitude of fluctuation of paddle has been limited in the gap of lubricating sleeve and paddle axis, the pressure that slip in lubricating sleeve and paddle in shaft clearance forms is by relief hole pressure release, reach interior pressure and outer pressure balanced, reduce the play of axle, extend the service life of cell body, gearbox, bearing.The 2nd, polytetrafluoroethylene (PTFE) or polyamide fiber material are selected in paddle positioning sleeve inner side, work impulsive force and the rigidity rubbing action of alleviating axle, and corrosion-resistant.The 3rd, it is two that positioning sleeve centering is cutd open, and adapter sleeve is bolted hole bolt and connects, and when energy fast assembling-disassembling after discovering and location cover parts depreciation or distortion, it is convenient to change.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1. lubricating sleeve 2. adapter sleeves, 3. relief hole, 4. bolt connecting hole.
Detailed description of the invention
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
As shown in Figure 1, a kind of paddle positioning sleeve, is characterized in that: comprise lubricating sleeve 1, adapter sleeve 2, relief hole 3 and bolt connecting hole 4, it is two that lubricating sleeve 1 cuts open with adapter sleeve 2 centerings, adapter sleeve 2 is bolted hole 4 use bolts and connects, and adapter sleeve 2 bottom center are drilled with relief hole 3.In the time that paddle rotates, the amplitude of fluctuation of paddle has been limited in the gap of lubricating sleeve 1 and paddle axis, and the pressure that the slip in lubricating sleeve 1 and paddle in shaft clearance forms, by relief hole 3 pressure releases, reaches interior pressure and outer pressure balanced, reduces the play of axle.
Lubricating sleeve 1 is selected polyamide fiber material, and cuing open with adapter sleeve 2 centerings of 316L material is two, and adapter sleeve 2 is bolted hole 4 use bolts and connects.The relief hole 3 of φ 20 mm bores in adapter sleeve 2 bottom center.Lubricating sleeve 1 is tight fit while assembling with adapter sleeve 2.Shaft clearance 2mm in lubricating sleeve 1 and paddle.Shaft end and adapter sleeve 2 gap, bottom surface 10mm in paddle.
The internal diameter of determining positioning sleeve when making according to the size that stirs axis, both are matched in clearance, and gap is large, and axis amplitude of fluctuation is large; Gap is little, easy stuck axis, general gap 2-3mm.Positioning sleeve divides two-layer, and internal layer (lubricating sleeve 1) contacts with the axis rotating rapidly, requires soft contact, work impulsive force and the rigidity rubbing action of alleviating axle, and corrosion-resistant, play to extend and stir cover and stir the axis effect in service life, material selection polytetrafluoroethylene (PTFE) or polyamide fiber material.Internal layer (lubricating sleeve 1) fits tightly with outer (adapter sleeve 2), is tight fit, for ensureing intensity, hardness and the decay resistance of positioning sleeve, adapter sleeve material selection Stainless steel 316 L.Relief hole 3 bores in adapter sleeve bottom center, and the pressure that the slip in lubricating sleeve and paddle in shaft clearance forms, by relief hole 3 pressure releases, reaches interior pressure and outer pressure balanced, reduces the play of axle.In paddle, gap 5-10mm is left in shaft end and adapter sleeve bottom surface, and gap is large, and slip easily precipitates in bottom surface; Gap is too small, easily blocks the passage that slip flows out from pressure relief opening.It is two that lubricating sleeve and adapter sleeve centering are cutd open, and adapter sleeve is bolted hole bolt and connects, and is convenient to fast assembling-disassembling.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes identical, should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
