Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of low-voltage switch equipment, in particular to an assembly component of a drawer bearing. Background Art
[0002] In the drawer-type design of low-voltage switchgear (such as GCK, GCS, MNS and other models), various electrical components are installed in a drawer cabinet that can be pushed in and out for easy maintenance and replacement. The propulsion mechanism on both sides of the drawer cabinet is equipped with guide rails and ball bearings, which can effectively reduce friction, while ensuring the stability of the drawer cabinet when pushed in and out, and reducing mechanical wear. In the prior art, the drawer bearing is assembled by a bearing-specific part, and the bearing is fixed to the side panel of the drawer cabinet by a riveting process. The bearing-specific part here is a customized riveting fastener, such as Figure 1 As shown. This assembly method has the following technical problems:
[0003] 1. The processing of bearing-specific parts is complicated and the cost is high;
[0004] 2. The installation process requires special pressure machinery;
[0005] 3. There is still a risk of falling off after riveting. The fallen installation parts fall inside the equipment cabinet and are difficult to handle, which may cause safety hazards. Utility Model Content
[0006] The utility model provides an assembly component for a drawer bearing, which has a simple and convenient assembly process, low cost, no need for additional pressure machinery, and reliable fixation without the risk of separation.
[0007] This application provides the following technical solutions:
[0008] A drawer bearing assembly assembly, including a bolt with a washer, a nut, a bearing, a bearing inner sleeve, a gasket and a washer, wherein the bearing inner sleeve is installed on the bearing inner ring, the bolt with a washer passes through the bearing inner sleeve, the mounting hole of the drawer partition, the gasket, the washer in sequence from the outside of the drawer partition and is connected to the nut, the bolt with a washer includes a screw, a nut and a bolt washer, the outer diameter of the bearing inner sleeve is the same as the diameter of the bearing inner ring, the inner diameter of the bearing inner sleeve is the same as the diameter of the screw, the length of the screw is greater than the sum of the bearing width, the drawer partition thickness, the gasket thickness, the gasket thickness and the nut height, and the diameter of the bolt washer is greater than the diameter of the bearing inner ring.
[0009] Technical principle: The outer diameter of the bearing sleeve matches the inner ring of the bearing, the inner diameter of the bearing sleeve matches the diameter of the screw, the screw passes through the sleeve and the drawer partition, and the bearing and the drawer partition are fixed by gaskets, washers and nuts.
[0010] Beneficial effects: The bearing sleeve provides support for the bearing to ensure stable operation of the bearing; at the same time, the bearing sleeve provides a reasonable installation position for the washer bolt. The washer bolt cooperates with the nut and the gasket to provide two-way fastening for the connection structure from the outside and inside of the drawer respectively. Compared with the traditional riveting process, the connection is more reliable and there is no risk of falling off.
[0011] During the installation process, no additional pressure machinery is required, which reduces the installation cost and makes the installation process simple and convenient.
[0012] Furthermore, the washer bolts, nuts, washers and gaskets used are all standard parts.
[0013] Beneficial effect: Assembly can be completed using standard parts, without the need for special customized parts, which greatly reduces costs.
[0014] Furthermore, the bolt with washer is a hexagon socket bolt with washer and a semi-circular head.
[0015] Beneficial effects: Standard parts are used, which are easy to purchase and low in cost, and the connection is stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a schematic diagram of the structure of assembling by means of bearing special parts in the prior art;
[0017] Figure 2 The utility model is a structural schematic diagram of an assembly component of a drawer bearing. DETAILED DESCRIPTION
[0018] The following is further described in detail through specific implementation methods:
[0019] The symbols in the drawings of the specification include: bolt with washer 1, bearing inner sleeve 2, bearing 3, washer 4, washer 5, nut 6.
[0020] Embodiment 1
[0021] like Figure 2 As shown, an assembly assembly of a drawer bearing includes a bolt with a washer 1, a bearing inner sleeve 2, a bearing 3, a gasket 4, a washer 5 and a nut 6, wherein the bearing inner sleeve 2 is installed on the bearing inner ring, the bolt with a washer 1 passes through the bearing inner sleeve 2, the mounting hole of the drawer partition, the gasket 4 and the washer 5 in sequence from the outside of the drawer partition and is connected to the nut 6, the bolt with a washer 1 includes a screw, a nut and a bolt washer, the outer diameter of the bearing inner sleeve 2 is the same as the diameter of the bearing inner ring, the inner diameter of the bearing inner sleeve 2 is the same as the diameter of the screw, the length of the screw is greater than the sum of the width of the bearing 3, the thickness of the drawer partition, the thickness of the gasket 4, the thickness of the washer 5 and the height of the nut 6, and the diameter of the bolt washer is greater than the diameter of the bearing inner ring.
[0022] The washer bolts, nuts, washers and gaskets used in this embodiment are all standard parts, wherein the washer bolts use washer semi-circular head hexagon socket bolts, which are easy to install and low in cost.
