[0002] A bearing is a device used to reduce mechanical friction, usually consisting of an inner ring, an outer ring, rolling elements, and a cage. Its function is to support and guide the rotating or linearly moving shaft so that it can run smoothly in the mechanical system. The bearing has a close relationship with the shaft. The bearing bears the task of supporting the weight of the shaft and resisting the friction and inertia force generated by the movement of the shaft. The bearing effectively reduces friction by rolling or sliding between the inner and outer rings through rolling elements (such as balls, rollers, etc.), thereby reducing the energy loss of the mechanical system and extending the service life of the shaft.
[0003] Bearing lubrication is the key to ensure smooth operation and extended service life of bearings. Proper lubrication can reduce friction and wear, reduce energy loss, and effectively cool and clean the inside of the bearing. Good lubrication can also reduce vibration and noise, improve the operating efficiency and reliability of the mechanical system, and thus ensure the normal operation of the equipment.
[0004] However, in high temperature and high humidity environments, bearings are prone to rust and damage, and lubricants may also clump or fail, which will have a serious impact on bearings. Utility Model Content

[0029] The technical solution provided by the utility model is further explained below in conjunction with embodiments.
[0030] This embodiment takes the bearing in the sterilizer for cultivating black boletus as an example to illustrate the structure of the bearing seat assembly.
[0031] Black Boletus is a kind of edible fungus, and it is the only one among more than 1,000 species of Boletus in the world that can be cultivated artificially and in factories. In the production of black boletus, the raw materials need to be sent to the mixer for mixing, and then bottled, sterilized, inoculated, cultured and other processes. Black Boletus can be sterilized in an autoclave. During the sterilization process, due to high humidity, high temperature and high pressure, the bearings of the drive part in the sterilizer are prone to rust and corrosion, and the high-temperature oil inside the bearing will evaporate in this harsh environment to form black solids, resulting in failure to play a normal lubrication role.
[0032] The inventor of the present application has found that it is troublesome to disassemble the bearing seat, and the work of disassembling the bearing seat, adding high-temperature oil to the inside of the bearing, and reassembling it will bring great labor intensity.
[0033] like Figure 1 As shown, a driving shaft 3, a driving sprocket 4, a driving chain 5, a driven sprocket 6, a driven sprocket shaft 7, a bearing seat 8 and a tray 11 are arranged in the box 1 of the sterilizer. A driving motor 2 is arranged outside the box 1.
[0034] The driving shaft 3 and the driven sprocket shaft 7 are both supported by the bearing seats 8. Two bearing seats 8 form a group, with a sprocket matching the shaft sandwiched between them, and the sprocket and the shaft rotate in conjunction. The bearing seats 8 are equipped with bearings matching the shaft. Figure 1 As shown, the driving shaft 3 is equipped with two driving sprockets 4, and then equipped with two sets of bearing seats 8; each driven sprocket shaft 7 is equipped with a driven sprocket 6, and then equipped with a set of bearing seats 8. The bearings of the bearing seats 8, the shaft supported by the bearing seats 8, and the sprockets clamped by the bearing seats 8 are coaxial. Figure 3 The fixed connection between the bearing seat 8 and the housing 1 is shown, and the bearing of the bearing seat 8 is coaxial with the driven sprocket 6. Figure 1 As shown, the driving shaft 3 is connected by a driving motor 2. The driving sprocket 4 and the driven sprocket 6 are connected by a driving chain 5.
[0035] When used, the driving motor 2 drives the driving shaft 3 to rotate, and the driving sprocket 4 is linked to rotate. The driving sprocket 4 rotates to drive the driving chain 5 to move, and the driving chain 5 moves to drive the driven sprocket 6 to rotate with the axis of the driven sprocket shaft 7 as the rotation center. Figure 2 As shown, the tray 11 is placed on the driving chain 5 and moves along with the driving chain 5 .
[0036] Therefore, the utility model provides a bearing seat assembly of a high-temperature sterilizer bearing which can extend the maintenance interval of the high-temperature sterilizer drive bearing and facilitate oil filling.
[0037] In order to solve the problem that the lubricant inside the bearing evaporates to form solid in the housing 1 and cannot play a lubricating role, and the problem of frequent disassembly of the bearing to inject lubricant into it, which causes a large workload, this embodiment provides a bearing seat assembly that is convenient for injecting lubricant. The bearing seat assembly encapsulates the lubricant and can be applied to the driving bearing of the high-temperature sterilizer to extend the maintenance interval of the high-temperature sterilizer bearing. An oil filling port is also provided so that lubricant can be added without disassembling the bearing. The bearing seat assembly includes: a bearing seat 8, an oil storage barrel 9 and an oil seal 10. In this embodiment, lubricating oil 12 is used for illustration, but in other embodiments, other types of lubricants with lubricating effects can also be used.
[0038] The bearing seat 8 is provided with a space for accommodating the bearing, and has a first side wall and a second side wall in the opposite direction to the first side wall; the first side wall is provided with a first opening communicating with the space; the second side wall is provided with a second opening communicating with the space.
[0039] The oil storage barrel 9 has an oil storage cavity for storing lubricating oil; an oil outlet and a circumferential wall surrounding the oil outlet are provided, the circumferential wall surrounds the first opening and is sealed with the first side wall so that the oil outlet and the first opening are connected; an oil filling port and a sealing cover are provided, and the sealing cover 13 is detachably sealed and connected to the oil filling port.
[0040] The oil seal 10 surrounds the second opening and is sealedly connected to the second side wall, and is provided with an oil seal opening suitable for the shaft to pass through and be sealedly connected to the shaft.
[0041] The oil storage barrel 9, the bearing seat 8, the oil seal 10 and the shaft together form a sealed cavity connected to the bearing, and the lubricating oil continuously lubricates the bearing in the sealed cavity.
[0042] The following description will be made by taking the matching bearing of the passive sprocket shaft 7 as an example. It should be noted that the matching bearing of the active shaft 3 can be installed with the bearing seat assembly using the same principle.
[0043] Figure 4 An exploded view of the passive sprocket shaft 7 is shown. The passive sprocket shaft 7 is sleeved with a passive sprocket 6, with bearings at both ends inserted into bearing seats 8, and the passive sprocket 6 is sandwiched between two bearing seats 8. Figure 4 Two bearings are installed in the bearing seat, but in other embodiments, one or more bearings may be installed. The two sides of the bearing seat 8 are sealed with the oil storage barrel 9 and the oil seal 10 respectively. The oil storage barrel 9, the bearing seat 8, the oil seal 10 and the driven sprocket shaft 7 together form a sealed cavity for storing lubricating oil 12, and the bearing is connected to the sealed cavity. Figure 5 The lubrication assembly after being filled with sealing oil 12 is shown. The oil seal 10 is arranged on the side of the bearing seat 8 close to the passive sprocket 6 and is sealed with the bearing seat 8. The oil seal 10 is provided with a circular opening, is sleeved on the passive sprocket shaft 7, and is sealed with the passive sprocket shaft 7. The oil storage barrel 9 is arranged on the side of the bearing seat 8 away from the passive sprocket 6, has a cavity for storing lubricating oil 12 and an opening that can cover the connection between the passive sprocket shaft 7 and the bearing seat 8, and the opening is sealed with the bearing seat 8. Figure 6 A schematic diagram showing lubricating oil 12 lubricating a bearing in a sealed cavity is shown.
[0044] To facilitate the filling of lubricating oil 12, Figure 7 It is shown that the oil storage barrel 9 is provided with an oil filling port, which is sealed by a sealing cover 13. When the lubricating oil 12 needs to be poured, it is only necessary to open the sealing cover 13 and fill the sealing cavity with oil through the oil filling port to lubricate the bearing.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the embodiments, a person skilled in the art should understand that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
