As shown in figures 1-6, the field disassembling tool for the crawler track chain of the bulldozer comprises a manual wheel 1, a first gear shaft 2, a manual wheel bolt 3, a front bearing 4, a first key 5, a belt wheel 6, a bearing seat 7, a second gear shaft 8, a second key 9, a gear 10, a rear bearing 11, a transmission rod bolt 12, a threaded transmission rod 13, a track chain clamping plate 14 and a push rod 15.
The main body of the manual wheel 1 is circular, three force applying rods are arranged on the outer ring, and an internal spline is arranged in the center. The main body of the first gear shaft 2 is a stepped shaft, an external spline is processed at one end, a key groove is processed in the middle, and a gear is processed on the main body. The center of the belt wheel 6 is provided with a round hole and a key groove, and the appearance is provided with a belt groove. The bearing frame is vertical four in all around, respectively sets up a bearing mounting hole on each bearing frame. The main body of the second gear shaft 8 is a stepped shaft, a key groove is processed in the middle of the main body, and two threaded holes are processed in one end face of the main body. The gear 10 is provided with a circular hole and a key slot in the center, and the shape of the gear is a gear structure. One end of the threaded transmission rod 13 is of a disc structure, two round holes are processed at the disc position of the root of the threaded transmission rod, and the main body of the threaded transmission rod is an external threaded rod. The bottom of the rail chain clamping plate 14 is a flat plate, one end of the rail chain clamping plate is provided with two bosses 14a, the upper part of the rail chain clamping plate is provided with a sliding seat 14c, and the center of the sliding seat 14c is provided with a square hole 14 b. The ejector rod 15 is long-strip-shaped, the cross section of the ejector rod is square, and internal threads matched with the threaded transmission rod 13 are machined inside the ejector rod.
The assembly sequence is as follows: installing a first key 5 and a belt wheel 6 on a first gear shaft 2, installing a front bearing 4 and a rear bearing 11 at two ends, and then installing the first key and the belt wheel on a bearing seat 7; the manual wheel 1 is combined with the internal spline and the external spline of the gear shaft 2 and fixed by a manual wheel bolt 3. A second key 9 and a gear 10 are arranged on a second gear shaft 8, a front bearing 4 and a rear bearing 11 are arranged at two ends of the second gear shaft, and then the second gear shaft and the gear are arranged on a bearing seat 7; two round holes at the root part of the disk of the threaded transmission rod 13 are aligned with two threaded holes at the end surface of the second gear shaft 8 and are fastened by a transmission rod bolt 12.
