Problems solved by technology

In the traditional gallbladder structure, the spindle bearing with the outer ring and the upper and lower bearing plates is pressed into the inner hole of the bearing seat. Since the installation inner holes of the spindle bearing and the bearing seat are not concentric, it is easy to cause the rod disc to be radially single. side force, resulting in unilateral wear of the parts, and the diameter of the spindle disk is determined by the outer diameter of the bearing seat, thus limiting the running speed of the spindle

Embodiment Construction

[0008] The present invention will now be described in detail with reference to the embodiments shown in the drawings.

[0009] Such as figure 2 As shown, the integral bearing ingot includes the bearing seat 4, the elastic tube 3, the oil cap 1, the ingot bottom sheet 6, the ingot bottom pad 7, the bushing 5, the ingot bottom pad 7, the ingot bottom sheet 6, and the bushing 5 are installed in sequence In the inner hole at the bottom of the elastic tube 3, the outer circle of the upper end of the elastic tube 3 matches the taper of the inner wall of the bearing seat 4. The inner hole of the bearing seat 4 between the upper end of the elastic tube 3 and the lower end of the oil cap 1 is fitted with a roller with a cage 2.

Abstract

The invention discloses an integral type bearing inner tube in a spinning ring spinning frame. The integral type bearing inner tube comprises a bearing block, an elastic tube, an oil preventing cap, a spindle bottom sheet, a spindle bottom mat and a lining, and is characterized in that a pin roller with a holder is clamped in the position, between the upper end of the elastic tube and the lower end of the oil preventing cap, of an inner hole of the bearing block. The inner wall of the bearing block, the upper end face of the elastic tube and the lower end of the oil preventing cap serve as an outer ring, a lower bearing plate and an upper bearing plate of the pin roller respectively to form an integral type bearing structure in a combined mode, the outer ring, the upper bearing plate and the lower bearing plate of a spindle bearing are eliminated, the requirement for the matching accuracy among parts is lowered, the concentricity of the bearing hole is guaranteed, the hole radial stress is even, and the service life of a spindle is prolonged; meanwhile, due to the fact that the outer diameter of the bearing block is reduced, the diameter of a wharve of the spindle is prompted to be reduced, high-speed operating of a smaller wharve can be adapted, and the operating speed is as high as 25000 r / min to 30000 r / min.

Description

Technical field [0001] The invention relates to a component of a textile ring spinning machine, in particular to an integral bearing spindle. Background technique [0002] The spindle is the key component of the spinning frame that plays the role of twisting and winding, and it is composed of a rod disc, a spindle and so on. In the traditional spindle structure, the spindle bearing with the outer ring and the upper and lower bearing plates is pressed into the inner hole of the bearing housing. Because the inner holes of the spindle bearing and the bearing housing are not concentric, it is easy to cause the rod disk to be radially single. When the force is applied, it causes unilateral wear of the parts. At the same time, the diameter of the spindle disk is determined by the outer diameter of the bearing seat, which limits the running speed of the spindle. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the ...
