Abstract
The utility model relates to a connecting device, particularly a connecting shaft device of an underwater pump with a long shaft, and the connecting shaft device is composed of an upper shaft, a lower shaft and a connecting block, wherein the shaft necks of the upper shaft and the lower shaft are mutually connected by the connecting block and are fixed by a connecting sleeve, thereby, the purpose of connecting is achieved. The utility model has the characteristics of compact structure, convenient installation and use, high precision, long service life, etc., and can be widely used for the connecting shaft device of an underwater pump.
Description
Technical field: the utility model relates to a kind of connection set, particularly relates to a kind of coupling shaft device that applies to long shaft submerged pump.
Technical background: long shaft submerged pump is because pump shaft is very long, and is far away from the liquid distance that extracts, so all adopt the major axis ways of connecting that pump shaft is coupled together.The pump shaft ways of connecting of long shaft submerged pump is a lot of now, but all not really desirable, often causes the concentricity of coupling shaft not high, connects instability, influences the working life of pump shaft easily, also can produce a large amount of noises simultaneously, can not meet the needs of production.The purpose of this utility model is exactly that a kind of brand-new connection set will be provided, and makes it not produce any noise in the running, and connection simultaneously is stable, firm, the working life that can improve long shaft submerged pump widely.
Summary of the invention: the purpose of this utility model is to realize like this, a kind of coupling shaft device is made up of last axle and lower shaft, it is characterized in that: described axle journal position of going up axle and lower shaft is respectively arranged with groove and connecting key, and will goes up with contiguous block and spool link to each other with lower shaft; Described contiguous block is made up of left and right two institutes, is respectively arranged with projection in the inboard of contiguous block, and its big I is inserted in the groove at axle journal position; By being divided into left and right two connecting sleeves of being formed, and be provided with groove in the arranged outside of upper and lower axle and contiguous block at the middle part of overlapping.The utility model modern design, easy to connect firm, can guarantee the coaxality between axle and the lower shaft well, thereby guarantee that long shaft submerged pump can not produce bigger noise when operation, can improve the working life of long shaft submerged pump widely.
Description of drawings: Fig. 1 is a structural representation of the present utility model
The utility model is described in further detail below in conjunction with accompanying drawing
In Fig. 1,1, go up axle 2, connecting sleeve 3, contiguous block 4, connecting key 5, lower shaft
Embodiment: in Fig. 1, a kind of coupling shaft device of the utility model is made up of last axle 1 and lower shaft 5, it is characterized in that: the axle journal position at last 1 and lower shaft 5 is respectively arranged with groove, and will go up spool 1 with contiguous block 3 and link to each other with lower shaft 5; Described contiguous block 3 is that left and right two of branch is formed, and is respectively arranged with projection in the inboard of contiguous block 3, and its big I is inserted in the groove at axle journal position; By being divided into left and right two connecting sleeves of being formed 2, and be provided with groove in the arranged outside of last axle 1, lower shaft 5 and contiguous block 3 at the middle part of connecting sleeve 2.During concrete the installation, be that the axle journal that will go up axle 1 and lower shaft 5 aligns mutually, two contiguous block 3 is enclosed within on the axle journal about will being divided into, make it can not move left and right, then will be equally also be that two connecting sleeve 2 is fixing with axle and contiguous block 3 about branchs, contiguous block 3 be fitted in the groove that is installed in connecting sleeve 2 at this moment.In order to prevent the slip of connecting sleeve 2, on last axle 1 and lower shaft 5, also have keyway, utilize connecting key 4 that it is fixed, and it is rotated together with the axis.The utility model is relatively simple for structure, and is easy for installation, and precision is also than higher, and can not produce very big noise during operation, improved its working life greatly.
Claims (2)
1, a kind of coupling shaft device is to have to go up axle (1) and lower shaft (5) is formed, and it is characterized in that: the axle journal position at last (1) and lower shaft (5) is respectively arranged with groove, and will go up spool (1) with contiguous block (3) and link to each other with lower shaft (5); Described contiguous block (3) is that left and right two of branch is formed, and is provided with projection in the inboard of contiguous block (3), and its big I is inserted in the groove at axle journal position.
2, a kind of coupling shaft device according to claim 1 is characterized in that: by being divided into left and right two connecting sleeves of being formed (2), and be provided with groove at the middle part of connecting sleeve (2) in the arranged outside of last axle (1), lower shaft (5) and contiguous block (3).
