Abstract

The present invention relates to a tilting-pad bearing, and belongs to the technical field of mechanical equipment bearing. The bearing comprises a bearing housing, pads, a support assembly and bearing end covers. The support assembly comprises a support block, a support cylinder, a pressure sensor and a gasket. A cylinder-shaped round table arranged in the front end of the support block is matched with the bearing housing, and is processed together with the bearing housing. The end surfaces of the bearing housing are provided with benches matched with the bearing end covers, oil inlet holes are arranged in circumferential directions of the end surfaces of the bearing housing, and the end surface of the bearing housing comprises four small planes, which are provided with four holes matched with the support block. The pad is one section of the thin-walled cylinder, two end surface of the pad are provided with benches and deep holes for installing a temperature sensor, the back surface of the pad is provided with a concave spherical surface matched with a support cylinder. The support cylinder is the cylinder with the spherical surface, and the spherical surface of the support cylinder is matched with the concave spherical surface of the back surface of the pad. The tilting-pad bearing provided by the present invention has the following advantages that: the production cost is low; the service life is long; the bearing running information can be real-timely monitored so as to provide a reliable guarantee for safe operation of the machine set.

Description

A kind of tilting-pad bearing

Technical field

The invention belongs to the machinery technical field of bearings, relate in particular to a kind of tilting-pad bearing.

Background technique

At present, the tilting-pad bearing that is used for the high speed rotating unit generally is made up of some tile fragments, and tile fragment is provided with the segmental tile back of the body eccentric with rotating shaft; Making itself and bearing housing is that line contacts; Therefore tile fragment can be swung at circumferencial direction, changes the angle of wedge that forms with journal surface, adapts to different operating modes.Yet because this structure causes the bearing requirement on machining accuracy high, difficulty is big, so cost of production is higher; And easy to wear, also bigger to the influence in working life; For guaranteeing the oil slick thickness between each tile fragment and rotating shaft axle journal, to its installation, debugging also comparatively inconvenience.

Summary of the invention

The present invention provides a kind of processing simple in order to address the above problem, debugging is convenient, and long service life can be monitored the tilting-pad bearing of runnability in real time.

Scheme of the present invention is achieved in that a kind of tilting-pad bearing is made up of bearing housing, four tile fragments, supporting component and bearing (ball) covers.Tile fragment is arranged in the bearing housing endoporus, and is axially spacing by the both sides end cap, and radially by the supporting component support, it is characterized by: said supporting component comprises support block, support cylinder, pressure transducer and pad; Said support block front end band tubular round platform cooperates with bearing housing, and processes together with one of which; Said bearing housing end face is provided with step and cooperates with bearing (ball) cover, and circumferencial direction has oil inlet hole, and four facets are arranged, and has four holes to cooperate with support block on the facet; Said tile fragment is a section of thin walled cylinder, and both ends of the surface have step, and is provided with deep hole with mounting temperature sensor, and a watt back of the body is provided with concave spherical surface and cooperates with support cylinder; Said support cylinder is a dribbling face cylinder, and sphere matches with tile fragment back side concave spherical surface.

The invention has the beneficial effects as follows: owing to adopt said structure, the bearing difficulty of processing is reduced, precision improves, thereby saves production cost; Adopt spherical support, make antiwhip better; Behind unit debugging or service wear, the adjustment spacer thickness can improve bearing performance, longer service life to suitable oil clearance; Monitoring tile fragment load reaches watt temperature in real time in unit running process, and the bearing operation information is held in support in time, reliable assurance is provided for the safe operation of unit.

Description of drawings

Fig. 1 is a radial structure schematic representation of the present invention.

Fig. 2 is an axial arrangement schematic representation of the present invention.

Among the figure: 1, upper end cap, 2, temperature measuring hole, 3, tile fragment, 4, support block, 5, bolt, 6, pad, 7, pressure transducer, 8, support cylinder, 9, bearing housing, 10, lower end cap.

Embodiment

Below in conjunction with accompanying drawing, technological scheme of the present invention is further described:

The present invention is made up of bearing housing, tile fragment, supporting component and bearing (ball) cover.Like Fig. 1, shown in Figure 2; Earlier with in the tile fragment 3 and the bearing housing 9 of packing into; It is spacing that end cap 1 lower end cap 10 is loaded onto at two ends respectively; Again with pack in the lump support block 4 and by the bolt 5 fastening supporting components of forming of the pad 6 of support cylinder 8, compressive force sensor 7 and suitable thickness, the supporting component bearing housing 9 of packing into, and the temperature transducer of packing at temperature measuring hole 2 places can make up with complete machine.Select suitable pad can guarantee the oil slick thickness of each tile fragment and rotating shaft axle strength during debugging; During operation, tile fragment is supporting the swing of bulb place, adjusts oil clearance automatically and makes the bearing operation more stable, and under the feedback of temperature transducer and pressure transducer, in real time the working condition of monitoring bearing.
