Abstract
An outer link of a chain relates to the technical field of various conveyor machinery, in particular to a chain structure. The outer link of the chain comprises a first outer link plate and a second outer link plate, wherein two first pin shaft holes are formed in the first outer link plate, and two second pin shaft holes are formed in the second outer link plate; and the first outer link plate is connected with the second outer link plate through two pin shafts. Each pin shaft comprises a cylindrical shaft body, and a first boss is arranged at one end of each cylindrical shaft body in a conjoined mode. Each cylindrical shaft body is arranged in the corresponding first pin shaft hole, and the other end of each cylindrical shaft body is connected with a fastener. A second boss is arranged at one end, where the first boss is arranged, of each cylindrical shaft body; the diameter of each second boss is smaller than that of each first boss; and each second boss is arranged in the corresponding second pin shaft hole. The outer link of the chain is flexible in mounting and dismounting, and the magnitude of interference of the pin shafts and the outer link plates is increased.
Description
Technical field
The utility model relates to various conveyor field of mechanical technique, relates in particular to the structure of chain.
Background technique
Bearing pin plays important supporting and connection function in chain, conventional conveyor chain upper pin one end band is taken, the other end punching dress fastener, and bearing pin and the connection of two outer plate interference fit form outer link.In assembly process in enormous quantities, because bearing pin and outer plate interference fit, the workman is difficult to a slice outer plate is installed to the root that the bearing pin band is taken by hand assembled, and is not only time-consuming but also require great effort during assembling, usually extends manufacture cycle, and consumes a large amount of manpower and materials.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of flexible mounting or dismounting to be provided, increasing the outer link of the chain of bearing pin and outer plate magnitude of interference.
The purpose of this utility model is achieved in that a kind of outer link of chain, comprises the first outer plate and the second outer plate, and two the first pin shaft holes are set on the first outer plate, and two the second pin shaft holes are set on the second outer plate; The first outer plate be connected outer plate and connect by two bearing pins, every bearing pin comprises respectively cylindrical axis body, one end of every cylindrical axis body respectively disjunctor arranges the first boss, every cylindrical axis body is separately positioned in corresponding the first pin shaft hole, and the other end of every cylindrical axis body connects respectively fastener; The end that every cylindrical axis body arranges the first boss respectively disjunctor arranges the second boss, and less than the diameter of the first boss, each second boss arranges respectively in corresponding the second pin shaft hole the diameter of each the second boss respectively.
Pin shaft structure of the present utility model increases by a step in the structure of traditional bearing pin, makes wherein that a slice outer plate is assembled to the interference shorten length of bearing pin root, thereby is convenient to mounting or dismounting and the maintenance aspect of outer link, has shortened installation time.Can also increase the magnitude of interference of this sheet outer plate and bearing pin.Operating torque when the anti-torque of assurance chain meshes greater than chain guarantees both quality and quantity to finish the production order.The utility model is applicable to the bearing pin in all trades and professions chain.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, be the outer link of chain, comprise arranging on two the first pin shaft hole 2, the second outer plates 5 on the first outer plate 1 and the second outer plate 5, the first outer plates 1 two the second pin shaft holes 6 are set.The first outer plate 1 be connected outer plate 5 and connect by two bearing pins 3, every bearing pin 3 comprises respectively cylindrical axis body 3-1, the end of every cylindrical axis body 3-1 respectively disjunctor arranges the first boss 3-3 and the second boss 3-2, less than the diameter of the first boss 3-3, each second boss 3-2 arranges respectively in corresponding the second pin shaft hole 6 diameter of each the second boss 3-2 respectively.Every cylindrical axis body 3-1 is separately positioned in corresponding the first pin shaft hole 2, and the other end of every cylindrical axis body 3-1 connects respectively fastener 4.
