Abstract
The utility model belongs to the chain drive technology field, especially relates to a driving chain tensioning mechanism which is mounted between a lower reduction box and an upper reduction box. The mechanism is composed of a swing rod, a pin shaft, a pin, a baffle plate, a nut, an adjusting bolt and a bolt; wherein the bolt is disposed on the baffle plate; a locking nut is mounted on the adjusting bolt; the baffle plate is mounted on the lower reduction box body by the bolt; and the swing rod is disposed on the upper reduction box body by the pin shaft and the pin. Advantages: by adopting the above technical scheme of mounting a driving chain tensioning mechanism between the upper reduction box and the upper reduction box, the utility model achieves the purpose of changing sprocket wheel center distance by defining the positioning pin between the upper and the lower reduction box as an axis, and rotating the upper reduction box around the axis by using the driving chain tensioning mechanism; thereby realizes the adjustment to the chain tension degree.
Description
Technical field
The utility model belongs to the chain transmission technical field, relates in particular to a kind of drive chain tensioning mechanism.
Background technique:
Chain-driven is a kind of mechanical transmission commonly used, and chain elongates the generation skidding in use for some time, so need be to apply a pre-tensioning to chain, in existing mechanical, chaindriven tensioning mode has three kinds: with the method tensioning of adjusting the centre of sprocket distance, with the method tensioning of shortening chain length, use the stretcher tensioning.Said method is adjusted all loaded down with trivial details operation, has awkward problem.
Summary of the invention:
In order to address the above problem, the purpose of this utility model provides on a kind of tensioning method of original adjustment centre of sprocket distance and installs simple, easily manufactured drive chain tensioning mechanism additional.
The technical solution of the utility model is: a kind of moving chain tensioning mechanism, and this mechanism is installed in down between speed reducer and the last speed reducer, and described speed reducer down and described going up between the speed reducer are provided with locating stud; It is characterized in that, this mechanism is made up of fork, bearing pin, pin, baffle plate, nut, adjusting bolt and bolt, wherein, described adjusting bolt is set on the described baffle plate, the described locking nut of socket on the described adjusting bolt, described baffle plate is installed on the described deceleration box down by described bolt, described fork is placed in described going up on the deceleration box by described bearing pin and described pin, regulate described adjusting bolt and drive described fork to drive the described deceleration box of going up be that the center produces rotation with the locating stud, change the centre of sprocket distance.
The advantage that the utlity model has is: owing to adopt technique scheme, the drive chain tensioning mechanism is being installed between speed reducer and the last speed reducer down, thereby reach following purpose: the locating stud in the utilization between speed reducer and the following speed reducer and as axle, utilizing drive chain tensioning mechanism structure to make the deceleration punch-out equipment is that the center produces rotation with the locating stud, changes the centre of sprocket distance.Thereby reach the purpose of adjusting the chain tension degree.
Description of drawings
Fig. 1 is the structural drawing of the utility model mechanism.
Among the figure: 1. fork 2. bearing pins 3. pin 4, baffle plate 5, nut 6, bolt 7, bolt
Embodiment
Fig. 1 is the structural drawing of the utility model mechanism.As shown in Figure 1, the utility model drive chain tensioning mechanism, this mechanism is installed in down between speed reducer and the last speed reducer, and described speed reducer down and described going up between the speed reducer are provided with locating stud; This mechanism is made up of fork 1, bearing pin 2, pin 3, baffle plate 4, nut 5, adjusting bolt 6 and bolt 7, wherein, described adjusting bolt 6 is set on the described baffle plate 4, the described locking nut 5 of socket on the described adjusting bolt 6, described baffle plate 4 is installed on the described deceleration box down by described bolt 7, described fork (1) is placed in described going up on the deceleration box by described bearing pin 2 and described pin 3, regulating the described deceleration box of going up of described fork 1 drive of described adjusting bolt 6 drivings is that the center produces rotation with the locating stud, changes the centre of sprocket distance.
Principle of the present utility model is:
When adjusting the chain tension degree, regulate the angle that bolt 6 changes fork 1 by rotation, adjust the position of deceleration box, making the deceleration punch-out equipment is that the center produces rotation with the locating stud, to reach the purpose of adjusting centre distance.When the tightness of chain is reasonable, lock with nut 5.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
