Description

Technical Field

[0001] This utility model relates to the field of oil pumping unit reduction drum technology, and in particular to a lubrication structure for a reinforced bearing of a tower-type oil pumping unit reduction drum. Background Technology

[0002] As one of the core pieces of equipment in the oil extraction field, the operational reliability of tower-type pumping units directly affects the efficiency of oilfield production. The reduction drum, as a key transmission component of the pumping unit, plays a crucial role in power transmission, speed reduction, and torque amplification. The reinforced bearing is the core component supporting the high-speed rotation of the reduction drum, and it must withstand alternating loads, impact loads, and frictional wear over long periods. Therefore, its lubrication effect is critical to the service life and operational stability of the equipment. The existing lubrication structure of the geared drum reinforced bearing of the tower-type oil pump has problems such as poor sealing and oil leakage during use, inability to adapt to repeated forward and reverse rotation, short lifespan, inability to adapt to low temperature environment and drum jamming, excessive grease consumption, and poor bearing lubrication. Utility Model Content

[0003] The purpose of this utility model is to provide a lubrication structure for the reinforcing bearing of the deceleration drum of a tower-type pumping unit, in order to solve the defects of the existing lubrication structure of the reinforcing bearing of the deceleration drum of the tower-type pumping unit, which has poor sealing performance and oil leakage, and cannot adapt to repeated forward and reverse rotation and has a short service life.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lubrication structure for a reinforced bearing of a deceleration drum in a tower-type oil pumping unit, comprising a drum body; A left support shaft is installed inside the main body of the roller, a left support seat is installed on the outer wall of the main body of the roller, and a flat key is installed on the outer wall of the main body of the roller; The drum body is equipped with a skeleton oil seal inside, and an input shaft is movably connected inside the drum body. A bearing body is installed on the outer wall of the input shaft.

[0005] Preferably, the roller body is engaged with the left support shaft via a flat key, and the roller body is engaged with the left support seat via a flat key.

[0006] Preferably, the left support seat has an open design, and the skeleton oil seal is placed between the left support shaft and the input shaft.

[0007] Preferably, the input shaft has a slotted design, and the bearing body is sleeved and installed on the outer wall of the input shaft.

[0008] Preferably, a self-aligning roller bearing is installed inside the roller body, and a sealing end cover is installed on the outer wall of the roller body, with a positioning bolt movably connected inside the sealing end cover.

[0009] Preferably, the sealing end cap has an open design, and the sealing end cap and the positioning bolt form a rotating structure.

[0010] Preferably, the inside of the roller body is provided with a threaded groove, and the roller body is threadedly connected to the positioning bolt.

[0011] The lubrication structure for the reinforced bearing of the reduction drum in a tower-type oil pumping unit provided by this utility model has the following advantages: The system consists of a drum body, left support shaft, left support seat, flat key, input shaft, and bearing body. Starting the motor inside the drum body drives the input shaft to rotate. Through the planetary gear mechanism within the cavity, the torque is ultimately output through the rotation of the drum body. During operation, the lubricating oil inside the drum body cavity is thrown upwards by the rotation of the drum body, and then flows into the bearing body through three small holes (10mm diameter) above the left support seat, thus providing lubrication. Furthermore, with the help of the flat key, the left support shaft and the left support seat can be installed on the drum body; Furthermore, since two oil-slinging grooves have been added to the input shaft, when the lubricating oil flows down, the oil-slinging grooves will throw the oil up and splash it onto the bearing body, so that both the inner and outer rings of the bearing body can be lubricated, further improving the lubrication effect on the bearing body. By setting up a drum body, a left support shaft, a self-aligning roller bearing, a sealing end cap, and positioning bolts, the self-aligning roller bearing is sleeved on the outer wall of the left support shaft, and the sealing end cap is moved to install it on one side of the drum body. The positioning bolts are passed through the sealing end cap and rotated, so that the sealing end cap can be limited to one side of the drum body, which facilitates the installation of the self-aligning roller bearing. Furthermore, the self-aligning roller bearings can further improve the sealing performance of the drum body and prevent oil leakage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 The present invention provides a lubrication structure for a reinforced bearing of a deceleration drum in a tower-type oil pumping unit, comprising a drum body 1.

[0016] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a left support shaft 2 is installed inside the drum body 1, a left support seat 3 is installed on the outer wall of the drum body 1, and a flat key 4 is installed on the outer wall of the drum body 1. There are two flat keys 4. A skeleton oil seal 5 is installed inside the drum body 1. An input shaft 6 is movably connected inside the drum body 1. A bearing body 7 is installed on the outer wall of the input shaft 6. The drum body 1 is engaged with the left support shaft 2 via the flat key 4 and the left support seat 3 via the flat key 4. The left support seat 3 has an open hole design. The skeleton oil seal 5 is placed between the left support shaft 2 and the input shaft 6. The input shaft 6 is connected to the output end of the motor inside the drum body 1. The input shaft 6 has a slotted design. The bearing body 7 is sleeved and installed on the outer wall of the input shaft 6.

[0017] By placing the left support shaft 2 on the outer wall of the drum body 1, both the left support shaft 2 and the left support seat 3 are positioned by the flat key 4 and remain stationary during operation. When stationary, the oil level is approximately at the center of the roller below the self-aligning roller bearing 8. During operation, the motor inside the drum body 1 drives the input shaft 6 to rotate, and through the planetary gear mechanism inside the cavity, the torque is ultimately output through the rotation of the drum body 1. During operation, the lubricating oil in the cavity of the drum body 1 is thrown to the upper part of the drum body 1 cavity by the rotation of the drum body 1, and then flows into the bearing body 7 inside through three small holes with a diameter of 10 mm above the left support seat 3. Because two oil-throwing grooves are added to the input shaft 6, when the lubricating oil flows down, the oil-throwing grooves throw the oil up and splash it onto the bearing body 7, so that both the inner and outer rings of the bearing body 7 can be lubricated.

[0018] Reference Figure 1 As shown, a self-aligning roller bearing 8 is installed inside the roller body 1, and a sealing end cover 9 is installed on the outer wall of the roller body 1. A positioning bolt 10 is movably connected inside the sealing end cover 9. The sealing end cover 9 has an open hole design. The sealing end cover 9 and the positioning bolt 10 form a rotating structure. A threaded groove is opened inside the roller body 1, and the roller body 1 is threadedly connected to the positioning bolt 10.

[0019] By fitting the self-aligning roller bearing 8 onto the outer wall of the left support shaft 2 and placing it inside the drum body 1, and then moving the sealing end cover 9 to install it on one side of the drum body 1, the positioning bolt 10 is passed through the sealing end cover 9 and rotated. Since the positioning bolt 10 is threadedly connected to the drum body 1, the sealing end cover 9 can be limited and installed on one side of the drum body 1, so that the self-aligning roller bearing 8 is stably installed inside the drum body 1.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
