Description
Technical Field
The utility model relates to a grid machine link joint technical field especially involves a low wearing and tearing guide pulley structure of grid machine link joint.
Background
At present, a plate type inner inflow grating chain plate structure in a sewage plant generally comprises chain plates, pins and guide wheels, wherein the guide wheels are connected to the left side and the right side of the chain plates through the pins. Because the guide pulley is directly connected with the pin and rubs, and the stress is applied to the pin, thereby causing the pin to wear greatly, need frequent change, bring certain influence for production.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned technical problem, provide a low wearing and tearing guide pulley structure of grid machine link joint, this structure can reduce the wearing and tearing between guide pulley and the pin, improves the life of guide pulley and pin.
The utility model discloses a realize above-mentioned purpose, the technical scheme who adopts is: the utility model provides a low wearing and tearing guide pulley structure of grid machine link joint, includes the link joint, the link joint has the guide pulley through the pin connection, be provided with the dead eye and the pinhole that are linked together in the guide pulley, be provided with the bearing of big or small adaptation on the dead eye, the pin passes bearing and pinhole in proper order and connects on the link joint, leave the clearance between pin and the pinhole.
As a further improvement of the utility model, be provided with two bearings that set up side by side in the dead eye.
As a further improvement, the outer end of the pin is provided with a limit hole, and a limit screw is installed on the limit hole.
As a further improvement of the utility model, the clearance between pin and the pinhole is 0.2mm at least.
As a further improvement of the utility model, the guide wheel is a nylon wheel.
As a further improvement, the bearing hole is arranged at the outer side, and the pin hole is arranged at the inner side.
The utility model has the advantages that: the utility model discloses in, the guide pulley passes through bearing and pin junction, makes between guide pulley and the pin direct contact not, avoids directly taking place the friction between the two, and utilizes the bearing to reduce the wearing and tearing of guide pulley and pin effectively, can improve the life of guide pulley and pin to need not to change guide pulley and pin frequently, guarantee the normal clear of production. In addition, the pin hole of the guide wheel has certain bearing capacity, and the gap is reserved between the pin hole and the pin, so that the pin hole is not contacted with the pin under normal conditions, but when the bearing is seriously abraded due to long-term use, the guide wheel and the pin can be connected through the pin hole, and a time transition is provided for replacement of the bearing.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The present invention will be further described with reference to the following embodiments and accompanying drawings.
As shown in fig. 1 and 2, a low-wear guide wheel structure of a link plate of a grating machine comprises a link plate 1, wherein the link plate 1 is connected with a guide wheel 3 through a pin 2, and the guide wheel 3 is a nylon wheel. The guide wheel 3 is provided with a bearing hole 31 and a pin hole 32 which are communicated with each other, the bearing hole 31 is positioned on the outer side, and the pin hole 32 is positioned on the inner side. The bearing hole 31 is provided with a bearing 4 with a size matched with the bearing hole, the two bearings 4 are horizontally arranged side by side, the pin 2 sequentially penetrates through the bearing 4 and the pin hole 32 and then is connected to the chain plate 1, a gap of 0.2mm is reserved between the pin 2 and the pin hole 32, the outer end part of the pin 2 is provided with a limiting hole, and the limiting hole is provided with a limiting screw 5.
The guide wheel 3 is connected with the pin 2 through the two bearings 4, so that abrasion of the guide wheel 3 and the pin 2 can be effectively reduced, and the service life is prolonged. A gap is reserved between the pin hole 32 and the pin 2, so that the pin hole 32 and the pin 2 are not in contact, when the bearing 4 is worn, the pin hole 32 is in contact with the pin 2, the guide wheel 3 is connected with the pin 2 through the bearing 4 and is switched to be connected with the pin hole 32, the phenomenon that the guide wheel 3 normally works due to the fact that the bearing 4 is worn is avoided within a certain time, and time transition is provided for replacement of the bearing 4. Through the setting of spacing hole and spacing screw 5, can avoid parts such as guide pulley 3, bearing 4 skew to cause the grid machine to damage even dropping to the grid machine.
The above embodiments are only used to conveniently illustrate the present invention, and are not intended to limit the present invention in any form, and any person who knows the knowledge generally in any field can use the present invention to make local changes or modifications in the equivalent embodiments without departing from the technical features of the present invention.
