Description

Technical Field

[0001] This utility model relates to the field of cement grinding roller presses, and more specifically, to a motor roller bearing housing for cement grinding roller presses. Background Technology

[0002] Cement roller presses, as a highly efficient and energy-saving grinding equipment, play a crucial role in the cement industry. This equipment mainly consists of two opposing and synchronously rotating extrusion rollers, one fixed and the other movable. The movable roller bearing housing, as a key component of the roller press, bears the enormous extrusive force exerted on the movable roller; its performance and stability directly affect the overall operating efficiency and lifespan of the roller press.

[0003] The existing cement mill roller press motor roller bearing housing still has the following problems during use:

[0004] (1) In the existing cement mill roller press motor roller bearing housing, the wear-reducing plate is usually made of polyvinyl fluoride. Although polyvinyl fluoride has certain self-lubricating and corrosion-resistant properties, under the long-term huge extrusion force and friction of the cement mill roller press motor roller, its wear resistance gradually decreases, which can easily lead to damage to the wear-reducing plate. Once the wear-reducing plate is damaged, it will not only affect the operation stability of the roller press, but may also cause more serious equipment failures, increase maintenance costs and downtime.

[0005] (2) The installation of grinding reduction plates on the existing cement mill roller press motor roller bearing housing often involves complex operations and long time consumption. Traditional installation methods may require the use of a large number of fasteners and special tools, which not only increases the difficulty of installation but also increases the installation cost.

[0006] Therefore, we have made improvements and proposed a bearing housing for the motor roller of a cement mill roller press. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a bearing housing for the motor roller of a cement mill roller press, which solves the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The cement mill roller press motor roller bearing housing is used to solve the above problems.

[0010] The application is as follows:

[0011] The device includes a base, the upper surface of which is provided with two friction-reducing plates, and an installation mechanism is provided between the friction-reducing plates and the base. A lubrication mechanism is provided between the base and the friction-reducing plates.

[0012] The friction-reducing plate is made of stainless steel.

[0013] The mounting mechanism includes mounting slots, and there are two mounting slots. Both mounting slots are located on the upper surface of the base, and the two friction-reducing plates are respectively engaged with the two mounting slots.

[0014] As a preferred technical solution of this application, the friction reducing plate has slots on both sides, the base has a sliding groove on the upper surface, and a movable plate is slidably connected inside the sliding groove. Two locking plates are fixedly installed on one side surface of the movable plate, and the locking plates are connected to the slots by a snap-fit ​​connection.

[0015] As a preferred technical solution of this application, the lower surface of the card slot is provided with a connection hole, and the lower surface of the card plate is fixedly installed with a card block, and the connection between the card block and the connection hole is a snap-fit ​​connection.

[0016] As a preferred technical solution of this application, a connecting groove is provided on the lower side of the slide groove, and a connecting plate is slidably connected inside the connecting groove. The connecting plate and the moving plate are connected in a fixed manner. A threaded rod is rotatably connected inside the connecting groove, and the connecting plate and the threaded rod are connected by a threaded connection.

[0017] As a preferred technical solution of this application, the upper surface of the base is provided with a mounting hole, and a rotating block is fixedly installed inside the mounting hole. The rotating block is fixedly connected to the top end of the threaded rod.

[0018] As a preferred technical solution of this application, the lubrication mechanism includes oil holes, and there are two oil holes. The two oil holes are respectively opened in the middle of the two friction-reducing plates. A connecting groove is opened inside the base and the connecting groove is connected to the two oil holes. An oil injection pipe is fixedly connected to one side of the base surface located on the side of the connecting groove. An oil groove is opened in the middle of the two friction-reducing plates.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. By using stainless steel friction-reducing plates and lubrication mechanisms, stainless steel, with its excellent hardness and corrosion resistance, can maintain the integrity and stability of the structure in environments that withstand huge extrusion pressure and frequent friction over a long period of time. This effectively reduces equipment failures caused by material wear and extends the service life of the bearing housing. At the same time, in conjunction with the lubrication mechanism, lubricant is injected into the oil injection pipe regularly. The lubricant can flow smoothly through the connecting groove and oil hole, and penetrate into the oil groove on the surface of the friction-reducing plate to form a uniform lubricating film. This further reduces the coefficient of friction, reduces energy loss, and ensures smooth operation between the moving roller and the bearing housing.

[0022] 2. By using the installation mechanism, the groove on the surface of the friction-reducing plate engages with the clamping plate on the moving plate, achieving initial fixation. Subsequently, the rotation of the threaded rod in the connecting groove pushes the connecting plate and the moving plate fixed thereto along the slide groove until the clamping block under the clamping plate engages tightly with the connecting hole, completing the secure installation of the friction-reducing plate. This design not only simplifies the installation steps, reduces the use of fasteners and special tools, and lowers installation costs, but also ensures precise positioning and tight fit between the friction-reducing plate and the base.
