Description

Deep groove ball bearing for textile machinery

Technical Field

The utility model belongs to the technical field of the bearing and specifically relates to a deep groove ball bearing for spinning machine.

Background

The original single-row radial ball bearing of the deep groove ball bearing is a rolling bearing which is most widely applied. It features small friction resistance and high rotation speed, and can be used for bearing radial load or combined load acted simultaneously in radial and axial directions, and also can be used for bearing axial load, such as small-power motor, automobile and tractor gear box, machine tool gear box, general machine and tool, etc.

In the field of spinning, due to the fact that a spinning machine generally runs for twenty-four hours without stopping, lubricating oil needs to be filled frequently, but the existing deep groove ball bearing needs to firstly detach the bearing from the machine during oil filling, then a sealing ring on the bearing is detached, the process is very complicated, and the efficiency is very low. Meanwhile, more dust and impurities exist in the textile field, so that the existing common dustproof effect cannot meet the requirements of the textile field.

In order to overcome the above-mentioned not enough of prior art, the utility model provides a deep groove ball bearing for spinning machine.

The technical proposal of the utility model for solving the technical problem is that: the utility model provides a deep groove ball bearing for spinning machine, includes bearing inner race, bearing outer race, is located the holder between bearing inner race and the bearing outer race, sets up the steel ball and the sealed sealing washer that sets up between bearing inner race and bearing outer race in the holder, its characterized in that: the sealing ring is provided with an inner ring, and the inner ring is detachably connected with the sealing ring.

Preferably, the sealing ring is provided with an annular connecting groove, and the annular connecting groove is matched with the inner ring.

Preferably, the outer side of the annular connecting groove is provided with an internal thread, the outer side of the inner ring is provided with an external thread, and the outer side of the annular connecting groove is in threaded connection with the outer side of the inner ring.

Preferably, a first contact surface is provided on an inner side of the annular connecting groove, a second contact surface is provided on an inner side of the inner ring, and the first contact surface and the second contact surface are in contact with each other.

Preferably, the first contact surface and the second contact surface are both inclined surfaces.

Preferably, the first abutting surface and the second abutting surface are in interference fit.

Preferably, the bearing outer ring and the bearing inner ring are both provided with annular clamping grooves, the sealing ring is provided with annular clamping protrusions, and the annular clamping protrusions are clamped into the annular clamping grooves.

Preferably, the outer side of the annular connecting groove is connected with the outer side of the inner ring through a fine thread.

Preferably, the inner ring and the upper end face of the sealing ring are arranged in a flush manner.

Preferably, the inner ring and the sealing ring are both made of rubber materials.

The beneficial effects of the utility model reside in that: through the bearing, when lubricating oil needs to be filled, only the inner ring needs to be screwed out, the replacement process is very simple, and the efficiency is greatly improved; when the bearing operates, the inner ring is screwed into the sealing ring and is integrated, so that the sealing performance of the bearing can be ensured.

Drawings

Fig. 1 is an overall sectional view of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a deep groove ball bearing for textile machinery comprises a bearing outer ring 1, a bearing inner ring 2, a retainer 3 positioned between the bearing outer ring 1 and the bearing inner ring 2, a steel ball 4 arranged in the retainer 3, and a sealing ring 5 arranged between the bearing outer ring 1 and the bearing inner ring 2 in a sealing manner, wherein an inner ring 6 is arranged on the sealing ring 5, and the inner ring 6 is detachably connected with the sealing ring 5. Through the detachable structure, the inner ring 6 can be detached when lubricating oil needs to be filled.

In this embodiment, the sealing ring 5 is provided with an annular connecting groove 7, and the annular connecting groove 7 is matched with the inner ring 6. Through the structure, the inner ring 6 and the sealing ring 5 are matched to form a whole, so that the sealing function of the sealing ring 5 can be realized when the bearing rotates to work.

Specifically, the outside of annular connecting groove 7 is equipped with internal thread 8, the outside of inner ring 6 is equipped with external screw thread 9, the outside of annular connecting groove 7 passes through threaded connection with the outside of inner ring 6. Through the structure, when the inner ring 6 needs to be filled with lubricating oil, a special tool is clamped in the screwing hole 14 of the inner ring 6, and then the inner ring is screwed in clockwise or screwed out anticlockwise through threads. And as preferred, this screw thread chooses for use fine screw thread, and is better inseparable during fine threaded connection, and the cooperation degree is better to can reach better sealed effect.

In the present embodiment, a first contact surface 10 is provided inside the annular connecting groove 7, a second contact surface 11 is provided inside the inner ring 6, and the first contact surface 10 and the second contact surface 11 are in contact with each other. The inner side of the inner ring 6 is abutted against the first abutting surface 10 on the inner side of the annular connecting groove 7 to form a seal through the second abutting surface 11, and the outer side is fastened through threads to realize complete sealing between the inner ring 6 and the sealing ring 5.

Preferably, the first contact surface 10 and the second contact surface 11 are both inclined surfaces. And the two adopt interference fit. The cooperation on inclined plane has guaranteed the cooperation inseparabler to make two butt faces extrude each other and form better sealed effect through interference fit. Therefore, it is preferable that both the inner ring 6 and the seal ring 5 are made of rubber. The composite material not only has good ductility, but also is a common sealing material and has high performance-to-cost ratio.

In this embodiment, bearing inner race 1 and bearing inner race 2 on all be equipped with ring groove 12, sealing washer 5 on be equipped with annular card protruding 13, annular card protruding 13 card go into ring groove 12 in. Through the structure, the sealing ring 5 is completely clamped between the bearing outer ring 1 and the bearing inner ring 2 to form better tight fit, so that a better sealing effect is achieved.

In the present embodiment, the inner ring 6 is flush with the upper end surface of the seal ring 5. By means of the above arrangement, better consistency is ensured, and the inner ring 6 is not obtrusive and affects the assembly with other parts.

The utility model has the advantages that: the bearing can be very simply filled with lubricating oil, and meanwhile, the sealing performance of the bearing can be ensured.

This embodiment is only one of the preferable embodiments of this patent, and any changes made without departing from the scope of this patent are within the scope of this patent.
