Description

Swing arm bearing seat type anti-torsion roller tank lug

technical field

The utility model relates to a roller jar ear for a vertical well hoisting container, in particular to a swing arm bearing seat type anti-torsion roller jar ear.

Background technique

At present, the articulation of the swing arm of the known roller pot and the base is to install the rotating shaft in the bearing seat of the base, drill a hole at the lower end of the swing arm and fit it on the rotating shaft, and then limit it with cotter pins and washers. Because the contact surface between the swing arm and the rotating shaft is very narrow, the swing arm will be slightly deflected after being stressed, and the swing arm has a high frequency of activities, coupled with the harsh environment, so this active part is easy to wear and tear after a period of use. Looseness occurs, especially at the end of the rotating shaft, so the service life of the existing roller lugs is very limited.

Utility model content

The purpose of the utility model is to provide a swing arm bearing seat type anti-torsion roller can ear, which can solve the deficiencies in the prior art.

In order to achieve the above object, the utility model realizes through the following technical solutions: it includes a swing arm, a roller assembly is installed at one end of the swing arm, a rotating shaft is arranged at the other end of the swing arm, the middle part of the rotating shaft is fixedly connected with the base, and a first bearing seat is respectively installed on the periphery of the rotating shaft. and the second bearing seat, the first bearing seat and the second bearing seat are fixedly connected with the swing arm, the first bearing is installed between the rotating shaft and the first bearing seat, and the second bearing is installed between the rotating shaft and the second bearing seat. Both the first bearing and the second bearing are joint bearings. Both the first bearing and the second bearing are deep groove ball bearings. Both the first bearing and the second bearing are sliding bearings. The first bearing seat and the second bearing seat are respectively in contact with two sides of the base.

The utility model has the advantages that: both ends of the rotating shaft realize rotation cooperation with the swing arm through bearings and bearing seats, and effectively increase the matching area between the swing arm and the rotating shaft, which can effectively solve the problem of easy wear and tear existing in the existing roller can ears, and greatly improve the The service life of the roller lugs.

detailed description

The swing arm bearing seat type anti-torsion roller tank ear of the utility model includes a swing arm 1, and a roller assembly 2 is installed at one end of the swing arm 1, and the feature is that: the other end of the swing arm 1 is provided with a rotating shaft 3, and the middle part of the rotating shaft 3 is connected to the base 4 Fixedly connected, the first bearing seat 5 and the second bearing seat 6 are respectively installed on the outer circumference of the two ends of the rotating shaft 3, and the first bearing seat 5 and the second bearing seat 6 are fixedly connected with the swing arm 1, and the connection between the rotating shaft 3 and the first bearing seat 5 The first bearing 7 is installed between them, and the second bearing 8 is installed between the rotating shaft 3 and the second bearing seat 6 . The two ends of the rotating shaft 3 of the utility model realize the rotation cooperation with the swing arm 1 through the bearing and the bearing seat, which eliminates the friction loss on the rotating shaft 3 during the movement of the swing arm of the roller tank ear, and at the same time, the bearing seat can also increase the swing arm 1 and the rotating shaft 3 The matching area is large, the stability between the swing arm 1 and the rotating shaft 3 is enhanced, and the swing arm 1 is prevented from shifting. Therefore, it can effectively solve the problem of easy wear of the existing roller lugs, and greatly improve the service life of the roller lugs. The service life can reach more than ten times that of the existing roller can lug products.

The first bearing 7 and the second bearing 8 described in the utility model can adopt a variety of bearing structures, such as joint bearings, deep groove ball bearings, and sliding bearings made of metal or polymer materials, etc., wherein the preferred bearing structure is The joint bearing, this structure can prevent the rotating shaft 3 from receiving radial torsion when the swing arm 1 moves, and prevent the rotating shaft 3 from bending after receiving force.

In order to prevent the swing arm 1 from moving axially along the rotating shaft 3, the utility model can adopt the following structure: the first bearing seat 5 and the second bearing seat 6 are in contact with both sides of the base 4 respectively. This structure can act as a stable limit between the swing arm 1 and the base 4 . Of course, the utility model can also realize the axial limit between the swing arm 1 and the base 4 through the bearing, but the requirement for the matching precision of the bearing is high, and it is difficult to ensure that there will be no looseness between the swing arm 1 and the base 4 .
