Abstract
The utility model discloses a kind of sheave block axle, comprise rotating shaft body, the guiding device be connected with rotating shaft body, described rotating shaft body comprises bearing support portion and pulley frame supporting part, and described pulley frame supporting part is the sunk part of the downward symmetry being arranged on rotating shaft body two ends; Described guiding device comprises the guide head of a taper, and described guide head is connected with described rotating shaft body, and be a dismountable structure between the two, the maximum diameter of described guide head is identical with the maximum diameter of rotating shaft body.The sheave block axle that the utility model provides, its structure is simple, easy for installation, both the significantly adjustment of driving had been transferred to when mounted and having adjusted by a small margin, the shock that turn avoid bearing inner circle and pulley spindle outer round surface damages, reduce the labor intensity of installer simultaneously, save the installation time, improve working efficiency.
Description
Technical field
The utility model relates to a kind of mechanical rotating shaft, particularly a kind of sheave block axle.
Background technique
Sheave block is that one is widely used in critical component in all kinds of grab bucket, uses axis, pulley, bearing easily to wear and tear, causes grab bucket normally to run.Therefore, need in daily production often to change parts, and the installation of pulley spindle is a very difficult job.Because, when installing pulley spindle, the concentricity requirement of pulley each bearing interior is quite high and is difficult to adjustment, slightly partially a bit, pulley spindle just cannot pass sheave block, and pulley spindle weight is large, need with driving lifting, the amplitude when adjusting pulley spindle position of driving a vehicle is large, cannot be adjusted to precise alignment, usually cause the shock of bearing inner circle and pulley spindle outer round surface to damage.
Model utility content
The purpose of this utility model is for solving the problem, and provides a kind of sheave block axle.
In order to achieve the above object, the utility model provides following technological scheme: a kind of sheave block axle, comprise rotating shaft body, the guiding device be connected with rotating shaft body, described rotating shaft body comprises bearing support portion and pulley frame supporting part, and described pulley frame supporting part is the sunk part of the downward symmetry being arranged on rotating shaft body two ends; Described guiding device comprises the guide head of a taper, and described guide head is connected with described rotating shaft body, and be a dismountable structure between the two, the maximum diameter of described guide head is identical with the maximum diameter of rotating shaft body.
Supplement as one of the present utility model, described guide head is provided with a connecting rod, the end of described connecting rod is provided with connecting thread, is arranged at one in the end of described rotating shaft body for placing connecting rod groove, and is provided with tapped hole in described groove.
Supplement as one of the present utility model, the tapering of described guide head is 10 °-15 °.
Beneficial effect:
The sheave block axle that the utility model provides, its structure is simple, easy for installation, both the significantly adjustment of driving had been transferred to when mounted and having adjusted by a small margin, the shock that turn avoid bearing inner circle and pulley spindle outer round surface damages, reduce the labor intensity of installer simultaneously, save the installation time, improve working efficiency.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of guiding device of the present utility model.
Fig. 3 is the structural representation that axle of the present utility model installs.
Embodiment
Below with reference to specific embodiment, the technological scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
A kind of sheave block axle as shown in Fig. 1 to Fig. 3, comprise rotating shaft body 5, the guiding device be connected with rotating shaft body 5, described rotating shaft body 5 comprises bearing support portion and pulley frame supporting part, and described pulley frame supporting part is the sunk part of the downward symmetry being arranged on rotating shaft body two ends; Described guiding device comprises the guide head 4 of a taper, and the tapering of guide head is 10 °-15 °.Described guide head 4 is connected with described rotating shaft body 5, and be a dismountable structure between the two, the maximum diameter of described guide head 4 is identical with the maximum diameter of rotating shaft body 5.
Further, described guide head 4 is provided with a connecting rod 7, the end of described connecting rod 7 is provided with connecting thread 8, is arranged at one in the end of described rotating shaft body 5 for placing connecting rod groove, and is provided with tapped hole 6 in described groove.
Before installation pulley spindle, by sheave block and pulley casing horizontal positioned, in the front end of rotating shaft body 5 axle, a taper guide head 4 is installed.The tapering of guide head is generally at 10 ° ~ 15 °.After guide head 4 and rotating shaft body 5 being combined, vertically sling, hole position alignment, adjusts the center of bearing 2 and pulley 1 while guide pulley axle is walked downwards in sheave block.So, both the significantly adjustment of driving transferred to and having adjusted by a small margin, the shock that turn avoid bearing inner circle and pulley spindle outer round surface damages, and reduces the labor intensity of installer simultaneously, saves the installation time, improve working efficiency.When after pulley spindle installation, guide head is pulled down.This guide head is nonexpendable item, repeated multiple timesly can use, one-time investment, uses all the life.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and supplement, these improve and supplement and also should be considered as protection domain of the present utility model.
