Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod processing and transmission, in particular to a roller device for reducing anchor rod wear. Background Art

[0002] It is well known that during the rolling process of the anchor rod, due to its large aspect ratio, different numbers of rollers need to be set as support according to the length of the material to prevent the anchor rod from bending due to lack of support. At the same time, it can also eliminate the destructive force of the anchor rod on the thread rolling wheel. In order to ensure that after the rolling of the anchor rod is completed and the rolling mill no longer provides axial thrust, the rollers can actively roll and drive the anchor rod to continue to convey the material. Generally, the rollers are driven by an external drive device to keep rotating rapidly to drive the anchor rod to discharge. However, during the rolling process of the rolling mill, the feed speed of the rolling mill and the feed rotation speed of the rollers are affected by various factors and are difficult to keep consistent. Due to the speed difference, sliding friction will inevitably occur between the anchor rod and the rollers during this process, thereby causing wear on the surface of the anchor rod and affecting the surface quality of the anchor rod. Utility Model Content

[0003] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a roller device for reducing the wear of the anchor rod, which can reduce the wear of the anchor rod while ensuring the support and transmission of the anchor rod.

[0004] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0005] A roller device for reducing anchor rod wear comprises a roller shaft and a cylinder body rollingly sleeved on the roller shaft via a rolling bearing; a sleeve is coaxially fixed to one end of the cylinder body, a one-way bearing is sleeved on the outer wall of the sleeve, a transmission wheel that can be driven to rotate by an external driving device is sleeved on the outer wall of the outer ring of the one-way bearing, and the driving rotation direction of the transmission wheel is the same as the locking direction of the one-way bearing.

[0006] Furthermore, bearing seats are fixed to the inner walls at both ends of the cylinder, and a rolling bearing is installed in each bearing seat.

[0007] Furthermore, the shaft sleeve is integrally connected with the corresponding bearing seat, and the corresponding end of the roller shaft is extended and inserted into the shaft sleeve through the gap.

[0008] Furthermore, the middle shaft of the roller shaft is expanded to form two step surfaces that respectively abut against the inner end faces of the inner rings of the two rolling bearings. The bearing seat connected to the shaft sleeve is provided with mounting grooves corresponding to the outer ends of the corresponding rolling bearings. The inner wall of the other bearing seat is provided with a retaining ring that abuts against the outer rings of the outer ends of the corresponding rolling bearings.

[0009] Furthermore, the shaft sleeve is connected to the inner ring of the one-way bearing via a first key.

[0010] Furthermore, the outer ring of the one-way bearing is connected to the transmission wheel via a second key.

[0011] Furthermore, the transmission wheel is configured to form a driven sprocket in a sprocket chain transmission pair.

[0012] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0013] The utility model discloses a roller device for reducing anchor rod wear. During the rolling process, when the power for the axial movement of the anchor rod is provided by the rolling mill, the driving wheel does not provide power, and the inner ring of the one-way bearing, the sleeve and the cylinder body rotate along with the anchor rod supported by the cylinder body. Due to the effect of static friction, the linear speed of the cylinder body is consistent with the travel speed of the anchor rod, and no relative sliding occurs. When the rolling is completed, the driving wheel is driven to rotate, and the inner ring and the outer ring of the one-way bearing are locked, so the driving wheel can drive the cylinder body to actively rotate and continue to convey the anchor rod forward to discharge the material, so that the anchor rod rarely has sliding friction with the cylinder body during the entire rolling and discharging process, which greatly reduces the wear of the anchor rod, improves the service life of the cylinder body, and also ensures the processing surface quality of the anchor rod.

[0020] The outer wall of the sleeve 2 is provided with a one-way bearing 8, which is an existing part that can rotate freely in one direction and be locked in the other direction; as needed, the sleeve 2 is connected to the inner ring of the one-way bearing 8 by a first key 5 to ensure that the sleeve 2 and the inner ring of the one-way bearing 8 can be circumferentially fixed, and the end of the first key 5 can also be axially fixed by installing a retaining ring; the outer wall of the outer ring of the one-way bearing 8 is provided with a transmission wheel 7 that can be driven to rotate by an external driving device, and the transmission wheel 7 is configured to form a driven sprocket in a sprocket chain transmission pair, and is driven by a motor; as needed, the outer ring of the one-way bearing 8 is connected to the transmission wheel 7 by a second key 6 to ensure that the outer ring of the one-way bearing 8 and the transmission wheel 7 are circumferentially fixed, and the end of the second key 6 can also be axially fixed by installing a retaining ring; the driving rotation direction of the transmission wheel 7 is the same as the locking direction of the one-way bearing 8, so that once the transmission wheel 7 is actively rotated, it can drive the sleeve 2 and the cylinder 3 to rotate together.
