Description

Description
SHAFT SUPPORT HAVING TWO ROLLERS CONTACTING THE SHAFT
Technical field
The present invention relates to a shaft support, in particular to a shaft support for a gas turbine.
Background art
A gas turbine and a generator are generally connected by an intermediate shaft therebetween. During installation or overhaul of the gas turbine, the two ends of the intermediate shaft must be disconnected from the gas turbine and the generator, and supported from below by a shaft support. The form of contact between an existing shaft support and a rotor shaft is a sliding connection, and the rotor shaft supported on the shaft support is not easily rotated during installation or overhaul of the gas turbine. In order to reduce friction between the rotor shaft and the shaft support to the greatest extent possible, such that rotation of the rotor shaft is easier, people have applied Teflon to the surface of the shaft support that is in contact with the rotor shaft, but the resistance arising from sliding friction is still considerable, causing great inconvenience for maintenance and overhaul of the gas turbine .
Content of the invention
The object of the present invention is to provide a shaft support which may be installed below the rotor shaft of a gas turbine, to facilitate rotation of the rotor shaft. Such a shaft support comprises: a first adjusting element and a second adjusting element, wherein one end of the first adjusting element and one end of the second adjusting element are separately connected to a base; a first connecting element and a second connecting element, wherein one end of the first connecting element and one end of the second connecting element are separately connected to the base, the other end of the first connecting element being connected to the other end of the first adjusting element, and the other end of the second connecting element being connected to the other end of the second adjusting element; and two rollers, wherein the two rollers are rotatably connected to a middle part of the first connecting element and the second connecting element, respectively. By way of rolling friction between the rollers and the rotor shaft, such a shaft support greatly reduces resistance during rotation of the rotor shaft, thereby facilitating rotation of the rotor shaft.
According to one aspect of the present invention, one end of the first connecting element and one end of the second connecting element are each connected to the base by way of connection to one and the same junction block. The junction block makes the connection between the shaft support and the base more reliable and convenient.
According to another aspect of the present invention, the first adjusting element and the second adjusting element both comprise a sleeve nut and two screws. One end of one of the screws has a left-hand thread, one end of the other screw has a right-hand thread, and the two screws are screwed into the two ends of the sleeve nut, respectively. The two ends of the sleeve nut have a left-hand thread and a right-hand thread, respectively, corresponding to the two screws. With such mating between the sleeve nut and the screws, the length of the first adjusting element and/or the second adjusting element can be changed by turning the sleeve nut, in order to adjust the position of the shaft support.
According to another aspect of the present invention, the first connecting element and the second connecting element are each a pair of parallel plates, the rollers being rotatably connected between the parallel plates and located at a middle part of the parallel plates. Using a pair of parallel plates results in the rollers being connected more reliably to the first connecting element and the second connecting element.
According to another aspect of the present invention, the shaft support is connected to the base by way of connection to a junction plate. The junction plate facilitates installation of the shaft support, thereby realizing a modularized design.
According to another aspect of the present invention, the shaft support comprises two junction bases fixed to the junction plate. Those ends of the first adjusting element and the second adjusting element that are connected to the bases are each connected to the junction plate by way of connection to the corresponding junction base. The junction bases make the connection between the shaft support and the junction plate more reliable.
According to another aspect of the present invention, the junction plate comprises two handles arranged symmetrically on the junction plate. The handles make it easier for the operator to hold the junction plate.
Preferred embodiments will be described below in a clear and easily comprehensible way with reference to the accompanying drawings, in order to further explain the above characteristics, technical features and advantages of the shaft support, and forms of implementation thereof.

Throughout the drawings, identical labels indicate identical components, or components which are similar in structure but have the same function; in some drawings, in the case of components which have the same structure or function, only one of these is illustratively depicted or marked. In order to make the appearance of the drawings simple, only those parts relevant to the present invention are illustratively shown in each of the drawings, and these do not represent the actual structure thereof as a product. "Connect", "fix" and "install" as used herein indicate direct "connection", "fixing" and "installation", or "connection", "fixing" and "installation" via a third component .
Fig. 1 and Fig. 2 show a shaft support 3 according to an embodiment of the present invention; the shaft support 3 in Fig. 1 is fixed to a base 30 via a junction plate 36. One end of a first adjusting element 11 is enclosed in a junction base 37, and is rotatably connected to the junction plate 36 by way of, for example, a pin 373 which passes through a hole 1121 (see Fig. 2) in a screw 112 (see Fig. 3(a)); one end of a second adjusting element 21 is enclosed in another junction base 37, and is rotatably connected to the junction plate 36 in the same way as the first adjusting element. The other end of the first adjusting element 11 is rotatably connected to one end of the first connecting element 12 by way of, for example, a bolt, while the other end of the second adjusting element 21 is rotatably connected to one end of the second connecting element 22 in the same way as the first adjusting element. At the same time, the other end of the first connecting element 12 and the other end of the second connecting element 22 are rotatably connected to a junction block 31 separately. The junction block 31 and junction plate 36 are connected by way of bolts or screws passing through four holes 311 (see Fig. 2) . Two rollers 34 are rotatably connected to a middle part of the first connecting element 12 and the second connecting element 22, respectively; the first connecting element 12 and the second connecting element 22 are each a pair of parallel plates 121 and 122, each roller 34 being connected between plate 121 and plate 122 by way of a bolt 35 (see Fig. 3(b), which shows a sectional view along section B-B in fig. 2) . The first connecting element 12 and second connecting element 22 may have exactly the same structure, while the first adjusting element
II and second adjusting element 21 may also have exactly the same structure. The junction plate 36 also comprises a handle 32, the handle 32 making it easier for the operator to hold the junction plate 36 in order to install the shaft support 3 on the base 30.
Fig. 3(a) shows a sectional view along section A-A in Fig. 2, in which the first adjusting element 11 comprises a sleeve nut
III and two screws 112 and 113. One end of the screw 112 has a left-hand thread and is screwed into one end of the sleeve nut 111 which similarly has a left-hand thread, while the other end of the screw 112 is one end of the adjusting element. One end of the screw 113 has a right-hand thread and is screwed into the other end of the sleeve nut 111 which similarly has a right-hand thread, while the other end of the screw 113 is the other end of the adjusting element. Such a design of adjusting element allows the lengths of the first adjusting element 11 and second adjusting element 21 to be changed by turning the sleeve nut (for example with a spanner), so as to change the distance between the two rollers in order to adjust the position of the rotor shaft. Fig. 3(c) shows a sectional view along section C-C in Fig. 2, in which the junction block 31 is connected between plate 121 and plate 122 by means of a bolt, and is able to rotate relative to the second connecting element 22.
Fig. 4(a) shows a partial schematic diagram of a junction plate
36 fitted with a junction base 37, while Fig. 4(b) shows a section view along section D-D in Fig. 4(a) . The junction base
37 comprises a junction base body 371 and a junction base support plate 372, wherein the junction base support plate 372 can be connected to the junction base body 371 by way of two screws 374 (see Fig. 1) . The junction base body 371 is fixed to the junction plate 36 by, for example, welding. One hole 375 passes through the junction base body 371, while another hole 376 passes through the junction base support plate 372, hole 375 and hole 376 being concentric. The shaft support 3 in Fig. 2 is assembled in advance, and subsequently connected to the junction plate 36. The connection process is to first install the junction plate 36 on the base 30, then fix the junction base body 371 to the junction plate 36, then insert the pin 373 (see Fig. 1) into the hole 375 and pass it through the hole 1121 in order to connect one end of the first adjusting element 11 to the junction base body 371, and finally fix the junction base support plate 372 to the junction base body 371 using the screws 374. One end 3732 of the pin 373 is inserted into the hole 375, such that a boss 3733 is blocked by an inner wall of the junction base body 371. Once the junction base support plate 372 is fixed on the junction base body 371, the other end 3731 of the pin 373 is partially inserted into the hole 376. Since part of the other end 3731 has a larger diameter than that of the hole 376 and is thus blocked, the pin 373 is unable to move along the axial direction of hole 375 and hole 376.
According to another embodiment of the present invention which is not shown, the junction block 31 need not be connected to the junction plate 36 or base 30 by having a slot mate with a lug 33, but may be connected in another way, for example by having a round rod mate with a cylinder. According to another embodiment of the present invention which is not shown, one end of the first connecting element 12 and one end of the second connecting element 22 may be connected directly to the junction plate 36 or base 30 by means of, for example, bolts, rather than via the junction block 31, so that the connection between the shaft support 3 and the junction plate 36 or base 30 is simplified.
According to another embodiment of the present invention which is not shown, the first adjusting element 11 and second adjusting element 21 need not employ mating between a sleeve nut and two screws, but instead employ another similar mechanism such as plug-pin mating, or any existing method.
According to another embodiment of the present invention which is not shown, the first connecting element 12 and second connecting element 22 may also be one plate or another rod, as long as the rollers 34 are able to contact the rotor shaft (not shown) during operation, and the strength permits it.
According to another embodiment of the present invention which is not shown, the junction plate 36 need not have a handle 32, but a handle 32 makes it easier for the operator to hold the junction plate 36.
According to another embodiment of the present invention which is not shown, the shaft support 3 need not comprise junction bases 37, but junction bases 37 can increase the reliability of connection between the shaft support 3 and the junction plate 36 or base 30.
According to another embodiment of the present invention which is not shown, the shaft support 3 may be connected to the base 30 directly rather than via a junction plate 36, but a junction plate 36 is helpful in realizing a modularized design for the shaft support 3, thereby facilitating installation. Those skilled in the art will understand that the rotatable connections in the various embodiments above may be accomplished by such means as bolts, screws or other similar mechanisms .
"Illustrative" as used herein indicates "serving as a real example, example or illustration", and no image or embodiment described herein as "illustrative" should be interpreted as being a preferable or more advantageous technical solution.
The series of detailed descriptions set forth above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention; all equivalent embodiments or modifications made without departing from the artistic spirit of the present invention should be included within the scope of protection thereof.
