Description
Technical field
The utility model relates to a kind of chain stretching devices, and in particular to a kind of new-type chain stretching device.
Background technique
Chaindriven application is more and more in mechanical device, and the chain stretching device on existing market uses limitation
Larger, the degree of tensioning adjusts more difficult, and service life is shorter, without good tensioning apparatus, chain used long it
After can generate loosening, and the loosening of chain is to machine operation, and processing can generate very big negative effect.
Summary of the invention
In order to overcome the shortage of prior art, a kind of new-type chain stretching device, the chain stretching device structure are proposed
Simply, powerful, it is simple and effective to be tensioned mode for the better tension chain of energy.The utility model is practical, high-efficient, body
Product is small, meets user demand.
The technical solution of the utility model are as follows: a kind of new-type chain stretching device, including pedestal, sprocket wheel, sprocket wheel pedestal, branch
Frame, tensioning adjusting rod and tensioning spring, the tensioning adjusting rod are mounted on the base, and the tensioning spring is mounted on described
It is tensioned on adjusting rod, the bracket is mounted on the base by a long axis, and the tensioning adjusting rod passes through a short axle
It is connected with the bracket, the sprocket wheel is mounted on the sprocket wheel pedestal, and the sprocket wheel pedestal is mounted on by a main shaft
On the bracket.
The utility model has the following beneficial effects:
The utility model structure is simple, powerful, the better tension chain of energy, and tensioning mode is simple and effective.This is practical
Bady is strong, high-efficient, small in size, meets user demand.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is that the utility model side connects structure schematic diagram.
In figure, 1- short axle；2- main shaft；3- bearing；4- long axis；5- bracket；6- sprocket wheel pedestal；7- pedestal；8- tensioning spring；
9- is tensioned adjusting rod；10- tensioning nut；11- sprocket wheel；12- chain；
Specific embodiment:
Referring to shown in Fig. 1 to Fig. 2, the utility model includes pedestal 7, sprocket wheel 11, sprocket wheel pedestal 6, main shaft 2, bracket 5, opens
Tight adjusting rod 9, tensioning spring 8, the tensioning adjusting rod 9 are mounted on the pedestal 7, and the tensioning spring 8 is mounted on described
It is tensioned on adjusting rod 9, the tensioning adjusting rod 9 is connected by a short axle 1 with the bracket 5, and the bracket 5 passes through one
Long axis 4 is mounted on the pedestal 7, and the sprocket wheel 11 is mounted on the sprocket wheel pedestal 6, and sprocket wheel pedestal 6 passes through two bearings 3
It is mounted on main shaft 2, the sprocket wheel pedestal 6 is mounted on the bracket 5 by a main shaft 2.Working principle are as follows:
By the tensioning nut 10 on rotation tensioning adjusting rod 9, tensioning spring 8 is compressed, tensioning adjusting rod 9 is driven to move,
The variation that angle occurs is rotated around long axis 4 by the bracket 5 that short axle 1 is connected with tensioning adjusting rod 9, and sprocket wheel 11 passes through master
Axis 2, sprocket wheel pedestal 6, bearing 3 are mounted on bracket 5, and the position of 5 rotating sprocket 11 of bracket also changes, to be achieved that
Tensioning to chain 12.
