Abstract
The utility model provides a chain mechanism of a conveyor and relates to the technical field of a conveying chain on the conveyor. The chain mechanism comprises a plurality of groups of external chain sections and a plurality of groups of internal chain sections, wherein the external chain sections in each group respectively comprise two external chain plates; the internal chain sections in each group respectively comprise two internal chain plates; the two external chain plates are connected with the two internal chain plates by pin shafts; a shaft sleeve is arranged on the pin shaft between the two external chain plates in a sleeving manner; a ball is arranged on a shaft sleeve between the two internal chain plates in a sleeving manner; grooving nuts are connected to the pin shafts on the external sides of the external chain plates through threads; and the grooving nuts are fixed together with the pin shafts through open pins. According to the utility model, sleeves and the internal chain plates are connected with each other in the form of interference fit so as to form the internal chain sections, the pin shafts with shoulders are used as chain hinge rotating shafts, the external chain plates are connected with the internal chain sections through the pin shafts with the shoulders so as to form a conveying chain, the grooving nuts are mounted at one ends of the pin shafts with the shoulders, and the fastened grooving nuts are inserted into the open pins so as to form a fastening structure. The fastening structure has a good locking function and has the advantage that relative rotation and loosening can be prevented. The chain mechanism of the conveyor, provided by the utility model, is mainly used for various places having high assembling precision and suffering from larger impact or variable load.
Description
Technical field
The utility model relates to the technical field of chain on the conveyer.
Background technology
Be connected into inner link by sleeve and inner plate interference fit, shouldered pin is as the chain axis of revolution, and pin link plate and inner link connect into chain by shouldered pin, wear the end that pin is contained in shouldered pin, forms fastening structure as fastener.This kind fastening structure is mainly used in the various conveyer chains.Traditional wearing locks that fixing structure is simple, the locking undercapacity.Important at some, cause that chain structure is whole to be damaged thereby assembly precision is high and be subjected to the place of greater impact or variable load the pin fracture usually easily to occur wearing.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of conveyor chain mechanism that is fastened securely to be provided.
The purpose of this utility model is achieved in that conveyor chain mechanism, comprise some groups of outer links and some groups of inner links, every group of outer link comprises respectively two pin link plates, every group of inner link comprises respectively two inner plates, two pin link plates with are connected an inner plate and connect by bearing pin, bearing pin between two pin link plates is nested with axle sleeve, axle sleeve between two inner plates is nested with ball, the fluted nut that is threaded on the bearing pin in the described pin link plate outside, fluted nut and bearing pin are fixed by spring cotter.
The utility model is connected into inner link by sleeve and inner plate interference fit, shouldered pin is as the chain axis of revolution, pin link plate and inner link connect into chain by shouldered pin, and fluted nut is contained in an end of shouldered pin, tighten rear insertion spring cotter and form a kind of fastening structure.This kind fastening structure locking function is good, can prevent from relatively rotating and getting loose.Be mainly used in the place that various assembly precisions are high and be subjected to greater impact or variable load.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be conveyor chain mechanism, comprise some groups of outer links and some groups of inner links, every group of outer link comprises respectively two pin link plate 1-1,1-2, every group of inner link comprises respectively two inner plate 2-1,2-2, two pin link plate 1-1,1-2 and two inner plate 2-1,2-2 connects by bearing pin 3, two inner plate 2-1,2-2 is arranged on two pin link plate 1-1, between the 1-2, at two pin link plate 1-1, be nested with axle sleeve 4 on the bearing pin 3 between the 1-2, at two inner plate 2-1, be nested with ball 5 on the axle sleeve 4 between the 2-2, the fluted nut 6 that is threaded on the bearing pin 3 in the pin link plate 1-1 outside, fluted nut 6 is fixing by spring cotter 7 with bearing pin 3.
