Technical Field
[0001] The invention relates to the technical field of power generation equipment, and in particular to a sliding bearing and a linear sliding bearing fastening device. Background Art
[0002] In the maintenance of power production, one of the essential tasks of the locomotive profession is the maintenance of sliding bearings of rotating mechanical equipment. During the operation and maintenance of rotating equipment several times, it was found that the traditional sliding bearing fastening device of rotating equipment broke many times. There were always errors between the processed sliding bearing fixture and the sliding bearing, and between the fastening screws and the sliding bearing seat, making it difficult to fix. The fitting surface of the sliding bearing and the fixture is not very tight, which affects the installation quality and installation time of the equipment. For example, many high-output water pumps in the steam turbine profession require sliding bearings for rotation support. There are many maintenance operations for rotating equipment. How to improve the quality of equipment installation, reduce accidents and improve work efficiency has become a problem, so the idea of making a linear sliding bearing fixture for rotating equipment was born. Summary of the invention
[0003] The invention of the linear sliding bearing fixing device is suitable for fastening and fixing the sliding bearings of water pumps and other similar rotating equipment. The traditional sliding bearing fixing device of rotating equipment is easy to break, and the fixing device that is processed and replaced is very likely to produce arc surface fitting errors, which brings difficulties to the installation work. The present invention solves this problem well and is simple and practical.
[0004] In order to achieve the above object, the present invention provides the following technical solutions: A linear sliding bearing fixing device, characterized in that it comprises: a linear sliding bearing fixing strip, two hexagonal bolts, and a positioning pin, wherein the linear sliding bearing fixing strip is a fixing device with an arc that is the same as the outer arc of the sliding bearing, and the three lines of the inner arc of the sliding bearing fixing strip fit the outer arc surface of the sliding bearing and are fixed to the bearing shell seat of the sliding bearing by two bolts, the linear sliding bearing fixing strip has two screw holes, symmetrically on both sides of the linear sliding bearing fixing strip, and a pin hole is provided at the top of the linear sliding bearing fixing strip, and the sliding bearing and the linear sliding bearing fixing device are connected by the pin. The screw is a component used to connect the linear sliding bearing fixing strip and the bearing seat, and the linear sliding bearing fixing strip and the bearing seat are connected by two screws, and the positioning pin is a component that connects the sliding bearing and the sliding bearing fixing strip, and there is a positioning hole at the top center of the linear sliding bearing fixing strip, and the sliding bearing and the sliding bearing fixing strip are connected together by the positioning pin to prevent the sliding bearing from moving left and right and front and back. The sliding bearing, bearing seat, shaft, linear sliding bearing fixing device, and bearing pressure cover are used to support the sliding bearing through the bearing seat to lift the shaft, the linear sliding bearing fixing device fixes the bearing shell, and then the bearing pressure cover is buckled.
[0005] Preferably, the linear sliding bearing fixing device is fitted and pressed against the outer arc surface of the sliding bearing by three inner arc lines and is fixed to the bearing bush seat of the sliding bearing by two bolts.
[0006] By implementing the above technical scheme, the following technical effects are achieved: a linear sliding bearing fixing device changes the surface-to-surface contact into surface-line contact, which effectively solves the problems of broken sliding bearing fixing strips, misaligned screw holes, and loose fitting. It has a simple structure, reliable quality, strong operability, and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 This is a schematic structural diagram of the linear sliding bearing fixing device provided by the present invention. DETAILED DESCRIPTION
[0008] In order to better understand the technical solution of the present invention, the embodiments provided by the present invention are described in detail below with reference to the accompanying drawings.
[0009] The embodiment of the present invention provides a novel linear sliding bearing fixing device, such as Figure 1 As shown, it includes: a fixing device 101, a sliding bearing 102, a pin 103, a fixing hexagon socket bolt 104, a fixing device inner arc surface linear strip 105, a pump shaft 106, and a sliding bearing frame 107. The fixing device 101 has a fixing pin 103 at the upper end, and the hexagon socket bolts 104 are fixed on both sides symmetrically. The fixing device 101 is attached to the outer arc surface of the sliding bearing 102 through the inner arc surface linear strip 105 of the sliding bearing. The sliding bearing 102 has a pin hole at the upper end, and is fixed to the fixing device 101 through the pin 103. The fixing device 101 is fastened to the sliding bearing frame 107 through the fixing hexagon socket bolt 104, and the sliding bearing device lifts the pump shaft 106 through the sliding bearing frame 107. ,.
