Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of guide shoe machining, and particularly relates to a radial tilting pad sliding bearing guide shoe machining method. BACKGROUND

[0002] Radial tilting pad sliding bearings are mostly applied to high-speed gearboxes, centrifugal compressors, permanent magnet high-speed motors, industrial drive steam turbines, small gas turbines, expanders and turbochargers, among which, the high-speed gearboxes and centrifugal compressors are the most commonly used. Existing compressor manufacturing enterprises have designed a series of centrifugal compressors, and users select the compressors of types close to the production process requirements. As an important supporting component of the high-speed stage of the centrifugal compressor, the radial tilting pad sliding bearing selects the bearing with a standardized width-diameter ratio from the bearing factory, so as to shorten the bearing manufacturing cycle and reduce the bearing procurement cost. The traditional bearing guide shoe is processed by machining an inner hole of a corresponding width, casting a bearing alloy, linear cutting into blocks, and finishing an outer circle and an inner hole of the guide shoe, and the production process is complex. The series of centrifugal compressors are adjusted by frequency conversion motors to meet the requirements of the production process, so that most of the series of centrifugal compressors do not work at the highest efficiency point, which causes a large amount of power loss.

[0003] Now, with the increasing requirements of energy saving and emission reduction, the demand for fine design of special compressors increases. In order to accurately match the design requirements of the special compressors, special radial tilting pad sliding bearings need to be designed for the special compressors, but the traditional production process of the special wide-diameter ratio radial bearing guide shoe causes a great extension of the manufacturing cycle, and improvement is needed. SUMMARY

[0004] The application aims to provide a radial tilting pad sliding bearing guide shoe machining method to improve the production and manufacturing efficiency of the guide shoe and reduce material loss.

[0005] The application provides a radial tilting pad sliding bearing guide shoe machining method, and the specific steps include: S1, preparing a steel pipe, shortening the steel pipe to a preset length, and machining an inner hole of the steel pipe; S2, cutting the steel pipe, cutting the steel pipe into six equal length strip-shaped shoe blanks by linear cutting, and the angle of each part is 60°; S3, forming a bearing alloy layer, placing the strip-shaped shoe blank on an adjusting clamp, forming the babbitt alloy on the inner hole surface of the strip-shaped shoe blank by welding or laser cladding, and annealing the shoe blank with the formed babbitt alloy to release the internal stress formed during the machining; S4, cutting the shoe blank, cutting the guide shoe with the required width on the strip-shaped shoe blank according to the design requirements; S5, finishing, finishing the outer cylindrical surface and the inner hole surface of the guide shoe to obtain the finished guide shoe.

[0006] The finishing process in step S7 adopts fine turning and / or fine milling and / or fine grinding.

[0007] The finishing in step S7 also includes processing of the oil guide groove and / or the oil guide hole.

[0008] The guide shoe processing method in the present application is mainly used for processing of non-standard wide-diameter ratio radial bearing guide shoes, which mainly have different widths from the guide shoes in the standardized wide-diameter ratio bearings. For the non-standard wide-diameter ratio radial bearing guide shoes, if the traditional processing method is used, the casting needs corresponding molds, the production efficiency is low, and the production cost is high. Therefore, the above processing method is proposed. The steel pipe is cut into a long strip-shaped shoe blank, then the babbitt alloy is formed on the inner hole surface of the long strip-shaped shoe blank by welding or laser cladding, and then the guide shoe with the corresponding width is cut according to the needs. The forming of the bearing alloy is not limited by the width of the guide shoe blank, the guide shoes with the same shaft diameter can share the blank, the guide shoe blank can be mass-produced in advance, and then it can be cut according to the required width. The bearing guide shoe manufacturing cycle can be greatly shortened. The thickness of the bearing alloy layer formed by the welding or laser cladding process can be greatly reduced, thereby reducing the bearing manufacturing cost. The design thickness of the bearing alloy of the radial tilting pad bearing guide shoe is generally 1-1.5 mm. When the welding or laser cladding forming process is used, the thickness of the blank bearing alloy only needs to be 1.5-2 mm, while when the centrifugal casting forming process is used, the thickness of the blank bearing alloy needs to be 7-8 mm. Generally, the processing batch of non-standard wide-diameter ratio radial bearing guide shoes is very small, most of which is single set. One tilting pad radial bearing uses five guide shoes with an angle of 60°, and one whole circular blank can be cut into six pieces. When the conventional process is used, the extra piece is basically wasted. However, when the method of the present application is used, the guide shoe width is cut according to the needs, and only the tail end of the long strip-shaped blank will have a little waste.

[0009] Further, the adjusting clamp comprises: a clamping assembly for clamping the long strip-shaped shoe blank, the clamping assembly comprising a clamping seat and a clamping block; a rotation adjusting structure for controlling the rotation of the clamped long strip-shaped shoe blank; a height adjusting structure for adjusting the axis height of the clamped long strip-shaped shoe blank; wherein the axis of the long strip-shaped shoe blank is the same as the rotation axis of the rotation adjusting structure, the height adjusting structure comprises an adjusting seat, the clamping seat is installed in the adjusting seat, the rotation adjusting structure comprises a base and a rotation shaft, the rotation shaft is movably installed on the base, and the rotation shaft is fixedly connected with the adjusting seat.

[0010] The inner hole surface of the long strip-shaped tile body is an arc surface, and welding or laser cladding generally adopts a welding head or a laser head. When the welding head or the laser head moves horizontally, the angle between the axis of the welding head or the laser head and the horizontal plane is unchanged, and a uniform forming layer can be formed on the plane. However, when the welding head or the laser head processes on the arc surface, the angle between the axis of the welding head or the laser head and the arc surface changes when the welding head or the laser head moves, which causes the non-uniformity of the forming layer. The long strip-shaped tile body can be adjusted by adjusting the clamp, so that a uniform bearing alloy layer is formed on the inner hole surface of the long strip-shaped tile body. The long strip-shaped tile body is clamped by the clamping assembly. The clamping block can move on the clamping seat. The long strip-shaped tile body is clamped on the two side planes of the long strip-shaped tile body by the clamping block. The long strip-shaped tile body is rotated by the rotation adjusting structure. During the welding or laser cladding process, the welding head or the laser head moves back and forth along the axis of the long strip-shaped tile body in the horizontal direction. When the welding or laser cladding changes direction, the tile body is rotated by the rotation adjusting structure. The arc surface which has not been formed with the bearing alloy layer corresponds to the processing position of the welding or laser cladding, so that the angle between the axis of the welding or laser cladding and the arc surface remains unchanged during the welding or laser cladding process. The rotation angle of the tile body is controlled by the rotation adjusting structure each time, so that the uniformity of the bearing alloy layer is realized. The position of the long strip-shaped tile body in the radial direction is adjusted by the height adjusting structure. The axis of the long strip-shaped tile body is the same as the rotation axis of the rotation adjusting structure. The rotation axis of the rotation adjusting structure is the axis of the rotation shaft. The bearing alloy layer can be formed on the tile body of different diameters by welding or laser cladding through the height adjusting structure. The adjusting seat and the rotation shaft are connected by fasteners such as bolts. The rotation shaft and the adjusting seat are connected by bearings to ensure the stability of the rotation of the adjusting seat. The clamping seat is installed in the adjusting seat. The relative movement between the clamping seat and the adjusting seat is controlled by the height adjusting structure.

[0011] Further, the clamping assembly further comprises: A rack is installed on each of the two clamping blocks. A gear is engaged with both racks and is installed on the clamping seat. A first worm wheel is coaxially connected with the gear. A first worm is installed on the clamping seat and is engaged with the first worm wheel. A support seat is installed in the clamping seat. A damper, a first spring, and a coil group are arranged between the support seat and the clamping seat. A coil group is installed in the clamping seat. A sliding seat is installed on the clamping block and is adapted to the coil group. The sliding seat has a conductive property. The clamping seat is provided with a sliding groove, the clamping block is provided with a sliding part corresponding to the sliding groove, the clamping block comprises a first abutting surface and a second abutting surface, the first abutting surface is perpendicular to the second abutting surface, the first abutting surface corresponds to and abuts against the two side planes of the long strip-shaped tile blank, and the second abutting surface abuts against the outer circular surface of the long strip-shaped tile blank.

[0012] Further, the height adjusting structure further comprises: The adjusting assembly comprises two hingedly connected adjusting rods, and the adjusting assembly is hingedly connected with the adjusting seat and the clamping seat. The driving assembly is arranged between two adjusting assemblies in the same group and opposite to each other, and the driving assembly comprises a first motor, a threaded rod and a nut seat.

[0013] Further, the rotating adjusting structure comprises: The second worm wheel is mounted on the rotating shaft. The second worm is mounted on the base and is engaged with the second worm wheel. The second motor is mounted on the base and is mounted in connection with the second worm.

[0014] Further, the adjusting seat is provided with a first arc surface, the base is provided with a second arc surface corresponding to the first arc surface, the first arc surface is provided with a limiting part, and the second arc surface is provided with a limiting groove corresponding to the limiting part.

[0015] The application has the following beneficial effects: 1. By forming a bearing alloy layer on the inner control surface of the long strip-shaped tile blank cut from a steel pipe, and then cutting the guide tile with a corresponding width as needed, the formation of the bearing alloy is not limited by the width of the guide tile blank, and the manufacturing period of the bearing guide tile can be greatly shortened.

[0016] 2. By using the welding or laser cladding forming bearing alloy process, the thickness of the formed bearing alloy layer can be greatly reduced, thereby reducing the manufacturing cost of the bearing.

[0017] 3. By using the long strip-shaped tile blank, only a small amount of loss will occur at the tail end of the long strip-shaped blank, thereby reducing the loss of the tile blank.

[0018] 4. During the welding or laser cladding process, the long strip-shaped tile blank is adjusted by the adjusting clamp to form a uniform bearing alloy layer on the inner hole surface of the long strip-shaped tile blank. BRIEF DESCRIPTION OF DRAWINGS
