FIG. 2 is a schematic view of an opening in an apparatus for bearing removal of the present invention;

fig. 3 is a schematic view of a tightening member of an apparatus for bearing removal according to the present invention.

In the figure, 1, a bottom plate, 2, a screw rod, 3 screw rod threads, 4 trapezoidal bearing clamping grooves, 5 screw rod fixing cylinders, 6 screwing nuts, 7, a first side plate, 8, a second side plate, 9U-shaped bearing clamping grooves and 10 knobs are arranged.

Detailed Description

The following describes a device for bearing removal according to the present invention in further detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 3, a device for bearing disassembly includes a bearing clamping groove, the bearing clamping groove includes a bottom plate 1, and a first side plate 7 and a second side plate 8 connected to one opposite side of the bottom plate, a lead screw nut 3 is fixedly connected to the first side plate 7 along a thickness direction thereof, the lead screw nut 3 is configured with a lead screw 2, a diameter and a length of the lead screw 2 can be set according to a bearing required by a job shop, and the lead screw 2 is used as a special disassembling device for the bearing, and penetrates through the lead screw nut 3 along a groove width direction of the bearing clamping groove; a stabilizing member is further arranged between the screw rod 2 and the first side plate, the purpose is to improve the stability of the screw rod in the screwing process and the disassembling efficiency, an opening is formed in the second side plate 8 corresponding to the bearing, one side of a bearing clamping groove is arranged on the outer side of the bearing shaft in operation, one side of the bearing clamping groove is sleeved on the bearing shaft through the opening, and a screwing piece is integrally formed at one end, far away from the second side plate 8, of the screw rod 2; the tightening member can be arranged as a screw-in nut 6 or a knob 10 according to the actual need.

As shown in fig. 2, the opening may be a trapezoid bearing slot 4 or a U-shaped bearing slot 9, and the bearing shaft is clamped through the opening, so that the bearing can be disassembled, and the flexibility of the disassembling operation is improved.

During operation, under the condition that the bearing clamping groove is sleeved on the bearing through the opening, the screw rod 2 is abutted to the bearing shaft, the screw component drives the screw rod 2 to increase the pressure between the screw rod and the bearing shaft, so that the force for separating the bearing shaft from the bearing is generated, the bearing clamping groove drives the bearing to separate from the bearing shaft, and the bearing is separated from the bearing shaft through the bearing clamping groove.

Further, the stabilizing member is a screw fixing cylinder 5, the screw fixing cylinder 5 is fixedly connected to the first side plate 7, and the screw 2 movably penetrates through the screw fixing cylinder 5. The diameter of the screw fixing cylinder 5 is slightly larger than that of the screw 2, so that the movement of the screw is not influenced on the premise of ensuring the stability of the screw.

Further, the other end of the lead screw 2 is provided with a frustum, and the bottom surface of the frustum is close to the first side plate 7. The arrangement of the frustum can improve the abutting positions of different shafts and improve the applicability.

Further, the radial dimension of the screw 2 and the shape and size of the opening are determined by the bearing. The matched size is set according to the fixed bearing at the fixed position in the workshop.

Further, the first side plate 7 and the second side plate 8 are perpendicular to the bottom plate 1. Therefore, the stability of the bearing clamping groove for clamping the bearing is improved.
