Abstract
A slope type axle locking device relates to a locking device used for preventing the axial moving of the axle in process of the railway axle bearing pressing installment, which comprises a cylinder (1), a cross beam (2) articulated with the cylinder (1), an inclined iron (3), a top block (4) and a guide rail (5), wherein, the inclined iron (3) comprises a big end (3-1) and a small end (3-2), an inclined surface (3-3) is formed between the small end (3-2) and the big end (3-1), the big end (3-1) of the inclined iron (3) is connected with the cross beam (2), one end of the top block (4) is provided with an inclined surface (4-1), the inclined surface (4-1) of the top block (4) is in horizontal contact with the inclined surface (3-3) of the inclined iron (3). The utility model prevents the axial moving of the axle and improves the working precision of the pressing installed bearing.
Description
Technical field: the utility model relates to and a kind ofly the railway wheel axle bearing is being press-fited the wheel shaft latching device that uses in the process.
Background technology: press-fit in the process at the railway wheel axle bearing, axial motion often takes place in wheel shaft, influences workmanship and efficient.
The utility model content: the utility model is exactly at the problem that press-fits wheel shaft generation axial motion in the process at wheel bearing, thereby provide a kind of ramp type wheel shaft latching device, it comprises oil cylinder 1, with oil cylinder 1 pivotally attached crossbeam 2, it also comprises wedge 3, jacking block 4 and guide rail 5, described wedge 3 comprises big end 3-1 and small end 3-2, form an inclined-plane 3-3 between big end 3-1 and the small end 3-2, the big end 3-1 of described wedge 3 is connected with crossbeam 2, end at jacking block 4 is provided with inclined-plane 4-1, the parallel contact of inclined-plane 3-3 of the inclined-plane 4-1 of jacking block 4 and wedge 3, described crossbeam 2, wedge 3 and jacking block 4 all are installed on the guide rail 5.The utility model has prevented the axial motion of wheel shaft, has improved the operating accuracy of pressing bearing.
Description of drawings: Fig. 1 is the utility model structural representation.
The specific embodiment one: present embodiment comprises oil cylinder 1, with oil cylinder 1 pivotally attached crossbeam 2, it also comprises wedge 3, jacking block 4 and guide rail 5, described wedge 3 comprises big end 3-1 and small end 3-2, form an inclined-plane 3-3 between big end 3-1 and the small end 3-2, the big end 3-1 of wedge 3 is connected with crossbeam 2, end at jacking block 4 is provided with inclined-plane 4-1, the parallel contact of inclined-plane 3-3 of the inclined-plane 4-1 of jacking block 4 and wedge 3, the gradient of jacking block 4 inclined-plane 4-1 is 1: 10-1: 60, the gradient of the inclined-plane 4-1 of jacking block 4 is identical with the gradient of the inclined-plane 3-3 of wedge 3, described crossbeam 2, wedge 3 and jacking block 4 all are installed on the guide rail 5, crossbeam 2 be installed in the axially vertical guide rail 5-1 of wheel shaft 6 on, wedge 3 is installed on the guide rail 5-2 parallel with guide rail 5-1, jacking block 4 is installed on the guide rail 5-3 vertical with guide rail 5-2, between the big end 3-1 of wedge 3 and small end 3-2, also has a plane 3-4, plane 3-4 is parallel with guide rail 5-2, wedge 3 contacts with guide rail 5-2 by plane 3-4, on jacking block 4, also have two plane 4-2 parallel with guide rail 5-3, jacking block 4 contacts with guide rail 5-3 by plane 4-2, and described oil cylinder 1 is captiveed joint with free bearing 7.
Under the promotion of oil cylinder 1, crossbeam 2 moves along guide rail 5-1, thereby driving wedge 3 moves, wedge 3 moves on guide rail 5-2, because the inclined-plane gradient of wedge 3 is identical with the inclined-plane gradient of jacking block 4, so its inclined-plane extruding jacking block 4 is to flank movement, thereby make jacking block 4 withstand wheel 8, eliminate jacking block 4 and the gap of taking turns the back side, when pressing bearing on wheel shaft 6, external force pass on the wedge 3 by jacking block 4 and and the supporting power of guide rail 5 balance each other, thereby the between centers string that has prevented wheel shaft is moving, has improved the operating accuracy of pressing bearing.
