Abstract
The utility model discloses an agricultural machinery camshaft power transmission device which comprises a fixed rod, a bearing piece and a shell, wherein the bearing piece comprises two ball bearings and a cylindrical roller bearing, clamping grooves formed in the inner ring of the shell are respectively sleeved outside the bearing piece, the fixed rod is positioned inside the bearing piece, a gasket is arranged between the inner ring of the shell and the bearing piece, and the gasket is positioned inside a limit groove formed in the inner ring of the shell; by arranging the limit groove on the outer shell and limiting the gasket arranged in the shell, the effect that the gasket cannot be separated from the shell along with the swing operation under the action of certain buffering and wear resistance can be realized, and the service life of the gasket is prolonged; meanwhile, compared with the traditional arc-shaped steel clamping plate, the bearing is additionally arranged in the arc-shaped steel clamping plate, so that the inner fixing rod can be better and smoother when rotating, friction force is reduced, and a good protection effect is achieved.
Description
Technical Field
The utility model belongs to the technical field of agricultural vibrating screens, and particularly relates to a cam shaft power transmission device of an agricultural machine.
Background
Vibrating screens are often used in the screening of foodstuffs. Compared with a linear vibrating screen, the eccentric shaft (wheel) vibrating screen adopts two groups of eccentric vibration exciters as vibration sources, so that the single exciting force of the eccentric mass of the vibration exciter is increased, the invalid vibration-taking weight is reduced to a certain extent, the exciting force can be randomly regulated and controlled, the large-scale and modularized design is facilitated, and the reciprocating motion is realized through the eccentric shaft, so that the screening work is performed.
At the junction of traditional shale shaker, used transmission shaft is connected with the dead lever (the dead lever is connected with the sieve, and the transmission shaft is connected with the bottom eccentric wheel) for provide power, in order to reduce friction and the collision that hard contact produced between the two during the swing, often use the cover to establish nylon cover or gum cover and locate the outside of dead lever, be connected with the transmission shaft after using arc steel splint to gum cover is fixed, but this kind of mode can produce heat when using inside dead lever motion and lead to its deformation, and arc steel splint department lacks the spacing to the gum cover, causes the phenomenon of falling easily when the swing, play good buffering and protection effect, influence its life.
Disclosure of Invention
The utility model provides an agricultural machinery camshaft power transmission device which comprises a fixed rod, a bearing piece and a shell, wherein the bearing piece comprises two ball bearings and cylindrical roller bearings, clamping grooves formed in the inner ring of the shell are respectively sleeved outside the bearing piece, the fixed rod is located inside the bearing piece, a gasket is placed between the inner ring of the shell and the bearing piece, and the gasket is located inside a limiting groove formed in the inner ring of the shell.
Further, the thickness value of the gasket is larger than that of the limiting groove, and the gasket extends to the outside of the limiting groove and is in contact with the bearing piece.
Further, the gasket is made of rubber.
Compared with the prior art, the utility model has the following beneficial effects:
according to the agricultural machinery camshaft power transmission device, the limiting groove is formed in the outer shell, and the gasket placed in the outer shell is limited, so that the inner part of the shell cannot be separated along with the swing operation under the action of certain buffering and wear resistance, and the service life of the device is prolonged; meanwhile, compared with the traditional arc-shaped steel clamping plate, the bearing is additionally arranged in the arc-shaped steel clamping plate, so that the inner fixing rod can be better and smoother when rotating, friction force is reduced, and a good protection effect is achieved.

Fig. 2 is a cross-sectional view of a fixing rod according to the present utility model.
Fig. 3 is a cross-sectional view of a housing in accordance with the present utility model.
In the figure: 1 fixed rod, 2 shell, 3 ball bearings, 4 cylindrical roller bearings, 5 washers.
Detailed Description
In order to facilitate an understanding of the utility model, the device of the utility model will be described more fully below with reference to the accompanying drawings. Examples of the apparatus are given in the accompanying drawings. However, the apparatus may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Examples
As shown in fig. 1-3, the embodiment provides an agricultural machinery camshaft power transmission device, which comprises a fixed rod 1, a bearing part and a shell 2, wherein the bearing part comprises two ball bearings 3 and a cylindrical roller bearing 4, clamping grooves formed in the inner ring of the shell 2 are respectively sleeved outside the bearing part, the fixed rod 1 is positioned inside the bearing part, a gasket 5 is placed between the inner ring of the shell 2 and the bearing part, and the gasket 5 is made of rubber. The packing ring 5 is located the spacing inslot portion that casing 2 inner circle was seted up, the thickness value of packing ring 5 is greater than the thickness value of spacing groove (i.e. the thickness value of packing ring 5 that is located the spacing inslot portion is greater than the thickness value of packing ring 5 that is located the outside of spacing groove), extend to the outside of spacing groove and contact with the bearing member, accomplish the spacing to inside packing ring 5 promptly through the spacing groove, along with the power drive of bottom, fluency when increasing dead lever 1 through the bearing member and rotate can reduce friction and the collision between dead lever 1 and the traditional arc steel splint, accomplish the protection to dead lever 1, and the packing ring 5 of inside rubber material can play good cushioning effect, accomplish the protection to the bearing member.
It should be noted that the structure of the present utility model may be implemented in many different forms, and is not limited to the embodiments, and any equivalent transformation made by those skilled in the art using the present specification and the accompanying drawings, or direct or indirect application in other related technical fields, such as loading and unloading of other articles, are included in the protection scope of the present utility model.
