Abstract
The utility model discloses a kind of material taking machine rotary reducer shaft coupling with abrasionproof function, comprise speed reducer input shaft (1) and shaft coupling (2), speed reducer input shaft (1) and shaft coupling (2) all offer keyway (3), shaft coupling (2) is positioned on speed reducer input shaft (1) by flat key (4), and the length of flat key (4) is identical with the length of the upper keyway (3) of speed reducer input shaft (1); The axle head central position of speed reducer input shaft (1) offers tapped hole (5), tapped hole (5) is provided with fixing bolt (6), fixing bolt (6) is provided with pad (7).It is simple that the utility model has structure, effectively can prevent flat key from wearing and tearing and lose, improve the working life of material taking machine.
Description
Technical field
The utility model relates to a kind of material taking machine rotary reducer shaft coupling with abrasionproof function, belongs to mechanical field.
Background technique
Material taking machine is conventional machinery, existing material taking machine after long-term use rotary reducer shaft coupling just has slight vibrations and abnormal sound, continue to use the situation that there will be abnormal sound and strengthen, find to have problems between rotary reducer input shaft and shaft coupling after repeatedly checking, then motor and speed reducer are thrown off, take shaft coupling apart, discovery is that the flat key wear and rupture loss be connected between input shaft with shaft coupling causes speed reducer abnormal sound and vibrations, this phenomenon generally occurs in most of material taking machine, therefore the shaft coupling structure design existing defects of existing material taking machine.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of material taking machine rotary reducer shaft coupling with abrasionproof function, and it is simple that it has structure, effectively can prevent flat key from wearing and tearing and lose, improve the working life of material taking machine.
The technical solution of the utility model is as follows: a kind of material taking machine rotary reducer shaft coupling with abrasionproof function, comprise speed reducer input shaft and shaft coupling, speed reducer input shaft and shaft coupling all offer keyway, shaft coupling is positioned on speed reducer input shaft by flat key, it is characterized in that: flat key length is identical with the length of keyway on speed reducer input shaft; The axle head central position of speed reducer input shaft offers tapped hole, tapped hole is provided with fixing bolt, fixing bolt is provided with pad.
Aforesaid have in the material taking machine rotary reducer shaft coupling of abrasionproof function, and described pad is circular gasket, and the diameter of pad is equal with the diameter of axle of speed reducer input shaft.
Aforesaid have in the material taking machine rotary reducer shaft coupling of abrasionproof function, and described pad is resilient pad.
Compared with prior art, the utility model by offering tapped hole on speed reducer input shaft, flat key is located by fixing bolt and pad, do not change the structure of former material taking machine speed reducer input shaft on the one hand, effectively prevent flat key on the other hand in use to wear and tear, rupture, improve the working life of equipment, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-speed reducer input shaft, 2-shaft coupling, 3-keyway, 4-flat key, 5-tapped hole, 6-fixing bolt, 7-pad.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
Embodiment of the present utility model: as shown in Figure 1, a kind of material taking machine rotary reducer shaft coupling with abrasionproof function, comprise speed reducer input shaft 1 and shaft coupling 2, speed reducer input shaft 1 and shaft coupling 2 all offer keyway 3, shaft coupling 2 is positioned on speed reducer input shaft 1 by flat key 4, it is characterized in that: the length of flat key 4 is identical with the length of keyway 3 on speed reducer input shaft 1; The axle head central position of speed reducer input shaft 1 offers tapped hole 5, tapped hole 5 is provided with fixing bolt 6, fixing bolt 6 is provided with pad 7.Described pad 7 is circular gasket, and the diameter of pad 7 is equal with the diameter of axle of speed reducer input shaft 1.Described pad 7 is compression spring.
Using method of the present utility model: first shaft coupling 2 is installed on speed reducer income axle 1, then the keyway 3 on shaft coupling 2 is aimed at the keyway 3 on speed reducer input shaft 1, and flat key 4 is inserted, for fixed coupling 2, after flat key 4 inserts keyway 3 completely, pad 7 is fixed on the axle head of speed reducer income axle 1 with fixing bolt 6, for locating flat key 4, prevent the flat key 4 when speed reducer works from producing axial displacement, extend the working life of flat key 4.
