Abstract
The utility model discloses a heavy type bush roller chain dividing the traditional fixed sleeve into three sections. The utility model is characterized in that a pin shaft is provided with a left rail node, a fixed sleeve, a movable sleeve, a fixed sleeve and a right rail node, wherein the fixed sleeve and the left and right rail nodes are interference fit, and the movable sleeve and the fixed sleeve are clearance fit. Thereby the utility model achieves circumferential abrasion of the movable sleeve and increasing service life. The utility model is applied to all the caterpillar engineering machinery, in particular to the caterpillar engineering machinery with pitch of over two hundred and three millimeters.
Description
The utility model relates to the chain technical field of tracked construction equipment, a kind of specifically heavy bush roller chaiin.
At present, in the construction machinery industry of China, from 80 horsepowers to 320 horsepowers crawler doer, the chain of crawler body is one of consumable accessory, and the chain consumable accessory then is the wearing and tearing of fixed cover.The structure of the crawler body chain of existing engineering mechanism is to connect with fixed cover between the two rails joint, and mode of motion is the surface of stirring fixed cover by the rotation of sprocket, realizes by the axle transmission.The shortcoming of this connection mode is: 1, cause lopsided wear owing to fixed cover can not rotate, service efficiency is low.2, because fixed cover and rail joint adopt interference fit, and dismounting needs compression machine to press-fit, and equipment such as bulldozer all belong to field work, therefore, change very difficulty of fixed cover.3, because the processing of fixed cover needs production machine, second the processing charges height is processed inconvenient first.
The purpose of this utility model provides a kind of heavy bush roller chaiin, fixed cover is become movable sleeve, thereby increase the service life, and reduces fittings cost.
The technical solution of the utility model is as follows: the sleeve of chain is divided into three sections, and promptly the fixed cover at two ends adopts interference fit with left and right sides rail joint respectively, the movable sleeve and the fixed cover free-running fit of middle rapid wear part.Its mounting structure is that right-to-left is with right rail joint, fixed cover, movable sleeve, fixed cover, left rail joint on bearing pin.Fixed cover and movable sleeve gap location have sealing member.Movable sleeve rotates along with the change of sense of motion, and becomes the contact of garden week by single face contact sprocket, has increased rubbed surface.
The utility model has the advantages that 1, improved service efficiency more than 2 times, it is convenient to change, and need not to press-fit, and only needs to change the intermediate active cover and gets final product.2, the handling ease of movable sleeve, general lathe just can be processed.3, save repair time.
Below in conjunction with accompanying drawing the utility model is further explained:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Fig. 3 is the structural representation of the utility model embodiment 3;
Embodiment 1: as can be known from Fig. 1, right-to-left is with right rail joint 1, fixed cover 3, movable sleeve 4, fixed cover 3, left rail joint 2 on bearing pin 5.Adopt interference fit between left and right sides rail joint and the fixed cover, two fixed covers insert the assembling of movable sleeve intermediate gap, and gap location is filled with sealing member 6.
Embodiment 2: as can be seen from Figure 2, right-to-left is with right rail joint 1, fixed cover 3, movable sleeve 4, fixed cover 3, left rail joint 2 on bearing pin 5.Adopt interference fit between left and right sides rail joint and the fixed cover, movable sleeve inserts two fixed cover intermediate gap assemblings, and gap location is filled with sealing member 6.
Embodiment 3: as shown in Figure 3, right-to-left is with right rail joint 1, fixed cover 3, movable sleeve 4, fixed cover 3, left rail joint 2 on bearing pin 5; Adopt interference fit between left and right sides rail joint and the fixed cover, movable sleeve and fixed cover adopt free-running fit, and gap location is filled with sealing member 6; Between fixed cover 3 and bearing pin 5, bearing 7 is housed.
Claims (4)
1, a kind of heavy bush roller chaiin comprises bearing pin, rail joint, fixed cover, it is characterized by: right-to-left is with right rail joint on bearing pin, fixed cover, movable sleeve, fixed cover, left rail joint; Two fixed covers save interference fit with left and right sides rail respectively, movable sleeve and two fixed cover free-running fits, and gap location is filled with sealing member.
2, a kind of heavy bush roller chaiin as claimed in claim 1 is characterized by, and movable sleeve inserts the fixed cover internal clearance and cooperates assembling.
3, a kind of heavy bush roller chaiin as claimed in claim 1 is characterized by fixed cover and inserts movable sleeve internal clearance cooperation assembling.
4, a kind of heavy bush roller chaiin as claimed in claim 1 is characterized by, and between fixed cover and the bearing pin bearing is housed.
