In view of the above-mentioned shortcomings in practice, the creators researched and improved on the aforementioned shortcomings, and finally created this creation.

The main purpose of this creation is to provide an improved structure of a buffer shaft seal anti-seepage bearing seat that will not be subject to radial tangential stress between the buffer and the shaft rod, so that oil leakage is less likely to occur.

In order to achieve the above purpose and effect, this creation is preset on the support frame of the cloth winding machine. The support frame has a plurality of cantilevers. Each cantilever is correspondingly provided with two hydraulic buffers, and the bottom of the cantilever has a rotatable connecting part , The two sides of the connecting portion respectively have a concave portion, and each concave portion corresponds to a hydraulic buffer, the hydraulic buffer is provided with a shaft, and one end of the shaft is provided with a pushing portion between the pushing portion and the hydraulic buffer A spring wrapped around the shaft is provided; the technical means adopted in this creation include: a cushion bearing, which has a horizontal bottom, and two sides of the horizontal bottom respectively extend symmetrically with an arc, and one side of the arc extends vertically A buffer hole arm is provided, and a set of holes is provided on the upper section of the two buffer hole arms, and the two buffer hole arms are inclined sideways along the bending angle of the arc to form a corresponding intersection line; the horizontal bottom is provided on the support frame of the aforementioned cloth winding machine, The two hydraulic buffers are respectively arranged in the sleeve holes on the upper section of the buffer hole arm. The pushing part at the front end of the hydraulic buffer respectively clamps the connecting part at the bottom of the cantilever, and the end of the pushing part is sleeved into the concave parts on both sides of the connecting part. In this way, when the cloth winding machine rotates or stops momentarily, the hydraulic shock absorber is along the corresponding intersection line of the side of the two buffer hole arms, which can appropriately offset the tangential stress of the support seat, so that the hydraulic shock absorber and the shaft There is no oil leakage between the rods due to tangential stress.

According to the above structure, the horizontal bottom of the buffer bearing is provided with a plurality of fixing holes, and a plurality of fixing pieces are passed through the fixing holes to fix the buffer bearing on the support frame.

Please refer to Figures 2 to 4, we can see that this creation is combined on a support frame 2 of a preset cloth winding machine 1, the support frame 2 has a plurality of cantilever arms 3, each cantilever arm 3 corresponds to two hydraulic buffers 4 and 4`, the bottom of the cantilever 3 has a rotatable connecting portion 31, each side of the connecting portion 31 has a concave portion 32, and each concave portion 32 corresponds to the hydraulic buffer 4, 4`, each hydraulic buffer The device 4 is provided with a shaft 41, 41', and one end of the shaft 41, 41' is provided with a pushing portion 42, 42', so that a covering shaft 41, 41 is provided between the hydraulic buffer 4, 4' `Spring 43, 43`, it should be noted that in this embodiment, the support frame 2 is a hexagonal structure, here It is just to simplify the drawing and reduce the complexity of reading. It does not limit the support frame connected in this case to only a hexagonal structure.

The structure of the present invention mainly has a buffer bearing 5, which has a horizontal bottom 51, and the horizontal bottom 51 is provided with a plurality of fixing holes 55, and correspondingly provided with fixing members 56 that can be combined and separated, and both sides of the horizontal bottom 51 An arc portion 52 is symmetrically extended, and a buffer hole arm 53 extends vertically on one side of the arc portion 52. The upper section of the two buffer hole arms 53 is provided with a set of holes 54 whose width of the outer diameter is at least equal to or greater than With respect to the width of the aforementioned buffer hole arm 53, the two buffer hole arms 53 obliquely form a corresponding intersection line along the bending angle of the arc portion 52.

When this creation is combined with the support frame 2 of the aforementioned winding machine 1, a plurality of fixing pieces 56 pass through the fixing holes 55 to fix the buffer bearing 5 on the support frame 2, and the hydraulic buffer 4 passes through the buffer hole arm 53 The sleeve hole 54 is fixed on the buffer hole arm 53 with a plurality of fitting pieces 44. The pushing parts 42 at the front end of the hydraulic buffer 4 respectively clamp the connection parts 31 at the bottom of the cantilever 3. In the concave portions 32 on both sides of the part, when the cloth winding machine 1 rotates or stops momentarily, the hydraulic shock absorber 4 follows the corresponding oblique line of the two buffer hole arms 53 side, which can appropriately cancel the buffer seat The tangential stress of 5 prevents oil leakage between the hydraulic shock absorber 4 and the shaft 41 due to the tangential stress.

Please refer to Figures 5 and 6 together. The first thing to explain is that in this creative embodiment, the circular rotation of the cloth winding machine 1 is described in a clockwise direction. However, the clockwise and counterclockwise directions are The subsequent technical description of this case is that the tangential stress F is in the opposite direction and does not affect the structure and technical characteristics of this case; when the cloth winding machine 1 starts, rotates, or stops momentarily, the hydraulic buffer 4 will follow the support frame The circular rotation motion of 2, there is a tangential stress F at any time, this tangential stress F reaches the maximum at the moment when the cloth winding machine 1 starts and stops Large, from the perspective of the hydraulic shock absorber 4, the hydraulic shock absorber 4 and the shaft 41 are forward tangential stress F, because the buffer hole arm 53 of the buffer seat 5 is arranged in a sideways manner, so, The hydraulic shock absorber 4 and the shaft 41 also exhibit a diagonal direction, and the shafts 41, 41' just form a centrifugal force angle θ with the tangential stress F, and the lateral diagonal direction is exactly the same as the forward tangential stress F direction Therefore, the hydraulic shock absorber 4 and the shaft 41 jointly receive the tangential force F in the same direction, and at the same time, extend along the horizontal bottom 51 and the arc portion 52 toward the tangential direction, forming an angle θ, the angle θ The angle difference just offsets the tangential stress between the hydraulic shock absorber 4 and the buffer seat 5, so the hydraulic shock absorber 4 and the shaft 41 will not be affected by the non-axial tangential stress F There is a problem of easy oil leakage; conversely, from the perspective of the hydraulic buffer 4', the shaft 41' and the hydraulic buffer 4'are reverse tangential stress F, because the buffer hole arm 53 of the buffer seat 5 It is arranged in a diagonal manner, so the hydraulic shaft 41` and the hydraulic shock absorber 4` also exhibit a diagonal direction, and the diagonal direction is exactly the same as the reverse tangential stress F direction, so the shaft 41` and the oil The pressure buffers 4′ jointly bear the tangential stress F in the same direction, and at the same time, extend along the horizontal bottom 51 and the arc-shaped portion 52 toward the tangential direction, forming an angle θ, the angle difference of the angle θ can offset the oil The tangential stress between the pressure buffer 4 and the buffer seat 5, therefore, there is no problem of oil leakage between the hydraulic buffer 4 and the shaft 41 due to the non-axial tangential stress F .

Based on the above, the improved structure of the buffer shaft seal anti-seepage bearing seat of this creation is actually a novel and progressive creation, and the application for a new type of patent is filed according to law; but the above description is only better for this creation The embodiment shows that any changes, modifications, changes or equivalent replacements based on the technical means and scope of the creation should also fall within the scope of the patent application for the creation.
