Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ball mills, and in particular relates to a high-efficiency sealing device for the gear cover of an ultrafine ball mill. Background Technology
[0002] The gear cover of an ultrafine ball mill is a critical protective component of the transmission system, primarily used to protect gears and bearings from dust and impurities, while also preventing lubricant leakage and ensuring stable equipment operation. Its core functions include protection, safety isolation, lubrication sealing, and noise and vibration reduction. In terms of material selection, gear covers are typically made of metal (such as carbon steel or stainless steel) to withstand heavy-duty or corrosive environments. Lightweight engineering plastics (such as nylon) can also be used to reduce weight, but they still have the following drawbacks in practical use:
[0003] During the installation of the gear cover of the ultrafine ball mill, the sealing ring needs to be embedded in the installation groove of the gear cover for installation and sealing. However, the operation of inserting the sealing ring into the installation groove is relatively troublesome and the overall installation of the gear cover is not convenient.
[0004] Secondly, during the sealing process, the gear cover is directly pressed against the outside of the ball mill using the installed sealing ring. As the ball mill rotates, the sealing ring will rub against each other. This friction will cause the sealing ring to be damaged quickly and need to be replaced, affecting its durability. Utility Model Content
[0005] The purpose of this utility model is to provide a high-efficiency sealing device for the gear cover of an ultrafine ball mill. By setting up a bottom mounting shell, a top mounting shell, a side mounting shell, and a sealing ring, it solves the problems that the overall installation and operation of the gear cover of the ultrafine ball mill is not convenient, and the sealing ring is prone to wear during operation.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a high-efficiency sealing device for the gear cover of an ultrafine ball mill, comprising a bottom mounting shell, a top mounting shell, a side mounting shell, and a sealing ring. A small gear shell is fixedly connected to one short side of the bottom mounting shell. A side mounting shell is provided on the top of the small gear shell, and a top mounting shell is provided on the top of the side mounting shell. The end of the top mounting shell away from the side mounting shell is in contact with the end of the bottom mounting shell away from the side mounting shell. The bottom mounting shell, top mounting shell, and side mounting shell together form a hollow annular structure. Sealing rings are provided at both ends of the bottom mounting shell, top mounting shell, and side mounting shell. During operation, the bottom mounting shell supports the outer shell of the ball mill. The installation of the top mounting shell and side mounting shell on the bottom mounting shell, through the mutual installation and combination of the bottom mounting shell, covers the meshing teeth of the large gear on the outer shell of the ball mill within the bottom mounting shell, top mounting shell, and side mounting shell, and the sealing ring seals the meshing teeth of the large gear within the bottom mounting shell, top mounting shell, and side mounting shell.
[0008] Furthermore, a sealing groove is fixed at the arc-shaped edge on both sides of the bottom mounting shell near the top opening, and a mounting frame is fixed at the outer edge of the bottom mounting shell near one end of the top mounting shell. A sealing groove is provided at the top arc-shaped edge of the bottom mounting shell to accommodate the sealing ring, and the mounting frame is fixed at the outer edge to be connected to the mounting frame of the top mounting shell by a screw.
[0009] Furthermore, mounting frames two are fixed to the upper part of the outer side of the pinion housing and the lower part of the outer side of the side mounting shell. A movable hole is opened at one short side of the top of the pinion housing, and a movable hole is also opened at the bottom of the side mounting shell at the position corresponding to the movable hole. Both mounting frames two are notched at the position of the mounting hole. Mounting bolts are inserted through the four corners of the two mounting frames two. Mounting frames two with notches are provided on the upper part of the pinion housing and the lower part of the side mounting shell, and are fixed by mounting bolts. Movable holes are opened at corresponding positions of the two to allow the pinion drive shaft to pass through. The notch design facilitates alignment and installation.
[0010] Furthermore, sealing grooves 2 are fixed at the arc-shaped edges near the bottom on both sides of the top mounting shell. One end of sealing groove 1 and one end of sealing groove 2 are in contact with each other. Mounting frames 3 are fixed at the outer edges near both ends of the top mounting shell. Mounting screws are fixed at the two upper corners of the mounting frame 3 on the side near the bottom mounting shell. The mounting screws are set close to the mounting frame 1. The mounting screws on the mounting frame 3 are inserted into the mounting frame 1 and extend out. Sealing grooves 2 are provided at the bottom arc-shaped edge of the top mounting shell and are connected to sealing groove 1. The mounting frames 3 on both sides are inserted into the mounting frame 1 of the bottom mounting shell by screws to achieve fastening and press the sealing ring.
[0011] Furthermore, sealing groove three is fixed at the arc-shaped edges on both sides of the side mounting shell. The two ends of sealing groove three are in contact with and connected to sealing groove one and sealing groove two, respectively. Sealing ring is movably connected in sealing groove one, sealing groove two and sealing groove three on the same side of the bottom mounting shell. Sealing groove three is provided on the arc-shaped edge of the side mounting shell, and the two ends are connected to sealing groove one and sealing groove two, respectively, forming an annular sealing channel. The sealing ring is embedded in the three grooves at the same time, dynamically sealing and preventing dust.
[0012] Furthermore, a mounting frame four is fixed to the outer edge of the side mounting shell near the top. The mounting frame four fits into each other with the mounting frame three on the top mounting shell near the side mounting shell. Mounting screws are also fixed to the two corners near the top on one side of the mounting frame four. The mounting screws on the mounting frame four pass through the mounting frame three near the mounting frame four and extend out. The mounting frame four of the side mounting shell is fitted and fixed to the mounting frame three of the top mounting shell by the screws, ensuring the overall structure is stable. The sealing groove three is aligned with the other sealing grooves to maintain the continuity of the seal.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of inconvenient overall installation of the gear cover of an ultrafine ball mill by setting up a bottom mounting shell, a top mounting shell, a side mounting shell, and a sealing ring. After placing the ultrafine ball mill in the bottom mounting shell, the mounting screw on the mounting frame three on the top mounting shell is inserted into the mounting frame one on the bottom mounting shell. At the same time, the sealing ring is locked in the sealing groove two to ensure that the small gear and the large gear mesh with each other. It is set in the small gear housing and locked in the movable hole. Then, the mounting frame four on the side mounting shell and the mounting frame three on the top mounting shell are aligned. After the mounting screw on the mounting frame four is inserted into the mounting frame three on the top mounting shell and extends out, the nut is screwed on it and pressed with the mounting frame three, so that the side mounting shell and the top mounting shell are installed together. At this time, the two mounting frames two are in close contact with each other. At the same time, the drive shaft on the small gear passes through the movable hole on the small gear housing and the top mounting shell, completing the installation. This makes the overall installation of the gear cover of the ultrafine ball mill more convenient and faster.
[0015] This invention solves the problem of wear on the gear cover sealing ring of an ultrafine ball mill during operation by setting up a bottom mounting shell, a top mounting shell, a side mounting shell, and a sealing ring. After the bottom mounting shell, top mounting shell, and side mounting shell are installed together, the meshing teeth of the large gear on the outside of the ball mill rotate in the cavities inside the bottom mounting shell, top mounting shell, and side mounting shell. At the same time, the sealing ring is movably connected to the sealing groove 1 on the bottom mounting shell, the sealing groove 2 on the top mounting shell, and the sealing groove 3 on the side mounting shell, and is pressed tightly by the bottom mounting shell, top mounting shell, and side mounting shell. During the operation of the ball mill, the rotation of the ball mill shell drives the sealing ring to rotate in the sealing groove 1 on the bottom mounting shell, the sealing groove 2 on the top mounting shell, and the sealing groove 3 on the side mounting shell. The sealing ring prevents dust and other substances from entering the bottom mounting shell, top mounting shell, and side mounting shell, making the gear cover sealing ring of the ultrafine ball mill less prone to wear during operation.
