Abstract

The utility model relates to an energy-saving durable chain. Each chain link comprises an outer chain plate, an inner chain plate, a middle guide shaft and outer guide barrel. The utility model is characterized in that the inner part of an inner hole of the middle guide shaft is provided with an inner core shaft which passes through the inner chain plate and the outer chain plate; both ends of the inner core shaft are provided with threads, and locking nuts are sheathed on the threads; a thread through hole is arranged on a radical position of the locking nuts and the threads of the inner core shaft, and the inner part of the thread through hole is provided with positioning screws; positions of both ends of the inner core shaft, which are sheathed with the outer chain plate are provided with axisymmetric flat tetracenes. The utility model has the advantages of energy saving, high durability, difficult abrasion, firm connection and difficult chain disjunction; in addition, the desquamation phenomena of the inner chain plate and the outer chain plate are difficut to happen when the energy-saving durable chain is used.

Description

The energy-saving durable chain

The utility model relates to a kind of chain, particularly a kind of energy-saving durable chain.

At present, various chain conveyors, plate chain type lift, scraper conveyor, plate bucket conveyor all adopt chain to transmit, promote operation, and the inside and outside carrier bar of each chain link of the chain that is adopted all uses coupling shaft to fix connection.What have is inserted in coupling shaft in the inside and outside carrier bar attachment hole, is riveted tightly in the coupling shaft two ends, has plenty of to adopt at the coupling shaft two ends that the pintle hook lock steel wire carries out internally, the outer plate pintle hook lock is fixed.They all exist exert oneself excessive or because of external force distortion or serious wear cause die damaged, polish or the wearing and tearing of steel wire pintle hook lock come off, to inside and outside carrier bar being come off and disconnecting, chain damages can not long-term security work.

The purpose of this utility model is to design a kind of energy-conservation, durable in use, inside and outside carrier bar difficult drop-off, and chain is difficult for the energy-saving durable chain of disconnection.

The purpose of this utility model is to realize like this, the every chain link of energy-saving durable chain comprises outer plate, inner plate, middle guide shaft, outer guide, there is inner axis of heart to pass inside and outside carrier bar in the guide shaft endoporus in the middle of it is characterized in that, there is screw thread at the two ends of inner axis of heart, be with locking nut on the screw thread, footpath at locking nut and inner axis of heart screw thread upwards is provided with a tapped through hole, and positioning screwn is arranged in the hole.Its cover outer plate place, two ends of inner axis of heart is provided with axisymmetric flat province.

By the energy-saving durable chain that the utility model provides, not only energy-conservation, and also durable in use, be difficult for abrasion, be connected firmly, inside and outside carrier bar difficult drop-off, chain are difficult for disconnecting.

The utility model has following accompanying drawing:

Fig. 1 is the structural representation of every chain link in the utility model.

Fig. 2 is the structure cut-away view that inner axis of heart of the present utility model, locking nut and positioning screwn are connected.

The utility model is described in further detail with reference to the accompanying drawings.Energy-saving durable chain, every chain link comprise outer plate 4, inner plate 5, middle guide shaft 6, outer guide 7, inner axis of heart 1, locking nut 2 and positioning screwn 3, as shown in Figure 1.There is screw thread at the two ends of inner axis of heart 1, and screw thread is through upwards there being tapped through hole, and cover outer plate place, two ends is provided with axisymmetric flat province, as shown in Figure 2.Middle guide shaft 6 outer guide 7 endoporus of packing into, flat province place, the two ends of sleeve 6 in the middle of inner plate 5 is contained in, the endoporus of guide shaft 6 in the middle of inner axis of heart 1 is packed into, outer plate 4 is enclosed within the flat province place of inner axis of heart 1, inner axis of heart 1 two ends thread bush upper locking nut 2, the tapped hole with on the nut 2 radial screw bore alignment inner axis of heart screws in positioning screwn 3, form chain link, this more piece is connected to form chain.This chain is durable in use, and is energy-conservation, not easy to wear, be connected firmly, and inside and outside difficult drop-off is difficult for making chain to disconnect.

Claims

1. energy-saving durable chain, every chain link comprises outer plate, inner plate, middle guide shaft, outer guide, there is inner axis of heart to pass inside and outside carrier bar in the guide shaft endoporus in the middle of it is characterized in that, there is screw thread at the two ends of inner axis of heart, be with locking nut on the screw thread, footpath at locking nut and inner axis of heart screw thread upwards is provided with a tapped through hole, and positioning screwn is arranged in the hole.

2. by the described energy-saving durable chain of claim 1, it is characterized in that its cover outer plate place, two ends of said inner axis of heart is provided with axisymmetric flat province.
