Problems solved by technology

Due to the small size of this type of equipment, cast aluminum is usually used to make the track. The track joints made of cast aluminum can meet strict size requirements, but there are also obvious deficiencies: cast aluminum has limited strength and is easy to deform. The vibration and impact of crawler mobile equipment during motion will cause the connecting shaft between the track joints to continuously squeeze and rub against the track joints at the shaft holes, and the shaft holes will gradually become larger due to this
Therefore, when the crawler-type mobile equipment is cornering or in the process of carrying heavy loads, it is easy for the limit end of the connecting shaft to come out of the shaft hole, causing the crawler to fall apart or disconnect, causing the equipment to fail to move normally.
[0003] Since the diameter of the shaft hole has changed, the loose connecting shaft under the conventional maintenance idea can only be scrapped and replaced with a connecting shaft with a larger shaft diameter. The root cause of the wear has not been eliminated. After a period of use, the repaired track will further wear at the shaft hole of the track joint, causing the replaced connecting shaft to loosen.

Embodiment 1

[0029] see Figure 1 to Figure 5 , crawler track anti-loosening maintenance method of the present invention comprises the following steps:

[0030] A. Remove the loose connection shaft 30 on the track to disconnect the two track joints 10 connected to the loose connection shaft 30, and measure the inner distance l and axis of the two inner ear plates 14 connected to the loose connection shaft 30 15 apertures, and use the larger shaft hole 15 aperture value as the outer diameter reference value d1, measure the middle shaft diameter of the loosely connected shaft 30 and use the corresponding shaft diameter value as the inner diameter reference value d2;

[0031] B. Make the limit shaft sleeve 40 with a circular tube with a length l, an inner diameter greater than the inner diameter reference value d2, and an outer diameter greater than the outer diameter reference value d1;

[0032] C. On the loose connection shaft 30, process a connection ring groove 31 with a width of 1 in th...

Embodiment 2

[0037] see figure 1 , 2 , 6, 7, crawler belt anti-loosening maintenance method of the present invention comprises the following steps:

[0038] A. Remove the loose connection shaft 50 on the track and disconnect the two track joints 10 connected with the loose connection shaft 50, measure the inner distance l of the two inner ear plates 14 connected with the loose connection shaft 50 and Aperture diameter of 15 shaft holes, and the larger diameter value of the shaft hole 15 is used as the outer diameter reference value d1, and the middle shaft diameter of the loosely connected shaft 50 is measured and the corresponding shaft diameter value is used as the inner diameter reference value d2;

[0039] B. Take a round tube with a length of 1, an inner diameter greater than the inner diameter reference value d2, and an outer diameter greater than the outer diameter reference value d1, and radially arrange at least one pair of pin holes 61 on the outer wall of the round tube to obta...

Abstract

The invention relates to the field of small mobile intelligent equipment repairing and maintenance, in particular to a track anti-loosening maintenance method. According to the method, a limiting shaft sleeve is additionally installed on a loosening connecting shaft, extrusion and friction between the loosening connecting shaft and a shaft hole can be effectively reduced, the loosening connectingshaft is prevented from falling off again due to the wear of the shaft hole, and as an original connecting shaft is still used, the maintenance cost can be significantly lowered. The method gives twoconcrete implementation forms, the limiting shaft sleeve in the two forms has certain activity space relative to the loosening connecting shaft, and thus the certain adaptability is achieved; and boththe limiting shaft sleeve and a modified structure of the loosening connecting shaft are easy to process and manufacture.

Description

technical field [0001] The invention relates to the field of repair and maintenance of small mobile intelligent equipment, and specifically refers to a maintenance method for preventing loosening of tracks. Background technique [0002] The track is usually a closed link formed by multiple track joints hinged to each other. As a moving mechanism for outdoor off-road equipment, the track can ensure its passability on roadless ground and reduce its driving resistance. In recent years, crawlers have also been gradually applied to small mobile smart devices, such as crawler robots and crawler AGVs. Due to the small size of this type of equipment, cast aluminum is usually used to make the track. The track joints made of cast aluminum can meet strict size requirements, but there are also obvious shortcomings: cast aluminum has limited strength and is easy to deform. The vibration and impact of the crawler mobile equipment in motion will cause the connecting shaft between the trac...
