Description

Apparatus for applying grease to bearing member

The present invention relates to a grease applying device for smooth operation of a large bearing member such as a tapered roller bearing mounted between a choke and a roll for smooth rotation operation of a hot roll used in cold rolling. Since the grease is automatically applied after the bearing member is positioned inside the connected block, the grease is uniformly applied to the entire surface of the bearing member. In particular, the bearing member enables easy grease application without manual labor. It relates to a grease applicator of.

In general, all driving bodies, that is, rolling rolls, are combined with bearings. For example, rolling rolls used for rolling heated slabs in cold rolling lamps are four-row tapered roller bearings mounted on chokes. The bearing, which facilitates the rotational operation of such a rolling roll, in particular a large bearing (hereinafter referred to as a 'bearing member') is coupled to the rotational operation, and is damaged due to friction during rotational operation and high heat generated by high-speed rotation. Grease should be applied for smoother rotational operation while preventing rolls. In case of rolling rolls, bearings and bearings are periodically inspected and disassembled. If there is no problem, grease is applied and then reassembled. It is usually difficult to reapply grease, so the application of grease is important when disassembling.

In the conventional grease application of the bearing member related to this technique, as shown in FIG. 1, the bearing member disassembled in the rotary table 120 which is driven while being driven with the air motor 110 on the work table 100. When the 130 is seated on the rotary table 120 by an operator or a small crane (not shown), the air motor 110 is driven to rotate the bearing member 130 at a constant speed and on one side of the work table 100. The grease G in the grease container is applied to the bearing member 130 by a worker by hand.

At this time, depending on the use condition and characteristics of the bearing member 130, a certain amount of grease (G) should be applied to the bearing member 130, for example, four-row tapered roller bearing for rolling rolls used in cold rolling process In the case of (130), grease should be applied accurately about 990g. If excessively applied grease (G) may cause a fire due to high heat generated during high-speed rotation, and if the amount of grease applied is small, friction Part breakage is caused by

However, in the grease application of the conventional bearing member as described above, as shown in FIG. 1, the worker manually works in a state in which the bearing member 130 is placed on the rotary table 120 driven on the work table 100. Due to the grease application, the more uniform grease application of the bearing member is not possible, that is, the grease is excessively applied or partially applied during the operator's misoperation. There is a problem that breakage occurs.

In addition, since the operator manually applies grease to the bearing member, a separate operator is required, and at the same time, the application of the driers is delayed, and thus, a smoother grease application is difficult, resulting in extremely poor workability. There was.

The present invention has been made in order to improve the various problems as described above, and its purpose is to cover the entire surface of the bearing member as an application block, and then, as a grease supply unit supplying grease at a predetermined time and a predetermined amount, Appropriate amount of grease can be uniformly applied to the whole bearing member according to the use environment and characteristics of the bearing member, which improves the operability of the bearing member, as well as the grease coating workability and the device using the bearing, that is, the operation of rolling roll An object of the present invention is to provide a grease applying apparatus for a bearing member that improves properties.

Referring to the operation and effects of the present invention made of the above configuration as follows.

As shown in Figs. 2 to 4, grease G is applied to a bearing member 20, such as a four-row tapered roll bearing or the like, used for driving a rolling roll for rolling a slab or the like in a cold rolling process. The grease applicator 1 of the bearing member, which can be applied automatically and uniformly and simply, is as follows.

First, as shown in FIG. 2, a hole is formed in the center portion of the work table 10 installed in a flat shape, and a bearing 12 is coupled therein, and a rotating shaft 42 is formed inside the bearing 12. Is inserted and fixed so as to rotate, a circular rotary table 40 is fixedly coupled to the upper end of the rotary shaft 42, the fixed bracket 14 installed on the work table 10 at the lower end of the rotary table 40 It is connected via a coupling to the drive shaft (44a) of the drive motor 44 mounted in the vertical direction as.

Therefore, when the drive motor 44 is driven, the rotary table 40 is integrally rotated, and in particular, the drive motor 44 uses a speed control motor to easily control the rotational speed as compared to the conventional air motor. In addition, the rotary table 40 is usually formed in a circular shape, and at the same time, the size thereof is mainly adapted to the size of the bearing member 20 to which grease (G) is applied.

On the other hand, as shown in Figures 2 and 3, the guide groove 46 is concave integrally in the radial direction of the central portion of the rotary table 40 is formed, the guide groove 46, two ball screws ( 48a and 48b are installed to rotate through the bearing block 48c. The one side ball screw 48a slightly protrudes from the outer circumferential surface of the rotary table 40 so that the operation handle 49 is spoken.

At this time, the two ball screws 48a and 48b are different screws, that is, if one is a left hand thread, the other is a right hand thread, and the two other screws are formed with ball screws 48a and 48b which are fixed blocks. Moving blocks 32a and 32b integrally coupled to the bottom of the 30 are respectively coupled.

Therefore, as shown in Figure 2, when the two fixing blocks (30a, 30b) is rotated the operation handle 49, two by two ball screws (48a, 48b) with different screws formed. The moving blocks 32a and 32b move in opposite directions, that is, in opposite directions that are separated or narrowed from each other, and thus the two fixed blocks 30a and 30b also move integrally.

That is, the operator seats the bearing member 20 on the rotary table 40, and then rotates the operation handle 49 to fix the inner ring portion 20a of the bearing member 20 to the fixed block 30a having an arc shape. (30b) to fix it firmly.

In addition, as shown in FIGS. 3 and 4, after seating and fixing the bearing member 20 to the rotary table 40, the application blocks 50a and 50b on both upper sides of the rotary table 40. When moving, the bearing member 20 is wrapped in the seating grooves 52a and 52b formed to face each other inwardly of the application block 50.
