When the stop ring is installed, the stop ring inevitably contacts the outer diameter of the bearing outer ring, the outer diameter of the bearing is often scratched, on one hand, the appearance quality of the bearing is influenced, on the other hand, the outer diameter of the bearing is uneven, and when the stop ring is installed, a bearing seat of a customer is scratched, and the installation of other parts is influenced.
SUMMERY OF THE UTILITY MODEL
In order to fish tail bearing external diameter when the snap ring is installed, the utility model provides a new snap ring installation device.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a stop ring mounting device for a single-row cylindrical roller bearing for preventing the outer diameter from being scratched is characterized in that a fixed block of the stop ring mounting device is a cone with a small upper part and a large lower part; the inner hole of the fixed block and the fixed block are eccentrically arranged, so that a structure that the maximum diameter of the left conical surface of the fixed block is larger than the outer diameter of the bearing, and the maximum outer diameter of the right conical surface of the fixed block is smaller than the outer diameter of the bearing is formed; the lower end of the fixed block is provided with a positioning shaft in clearance fit with the bearing inner ring; an elastic pressing sheet is arranged on the right conical surface of the fixed block; the elastic pressing sheet is obliquely arranged, and the lower end of the elastic pressing sheet is positioned outside the end face of the bearing outer ring; the stop ring mounting device is also provided with a press mounting ring which is convexly and concavely buckled with the fixed block; the press-fitting ring is provided with a press-fitting plate positioned above the fixing ring; the lower part of the press-fitting plate has a ring-shaped structure for press-fitting onto the snap ring.
The stop ring is in a ring shape with a fracture and has certain elastic deformation capacity.
The press mounting ring is provided with a wedge-shaped block protruding downwards on the press mounting plate, and a wedge-shaped groove buckled with the wedge-shaped block is formed in the fixing block.
The utility model provides a prevent single-row cylindrical roller bearing of external diameter fish tail and use retaining ring installation device, when installing, block one side of retaining ring in the bearing outer lane retaining ring breach, the other end is put on the elastic pressure piece of locating piece; after the stop ring is placed, the press-mounting ring is held by a hand to be pressed downwards, and when the conical positioning pin on the press-mounting ring is completely matched with the conical hole on the fixing block, the stop ring is installed; because the large outer diameter of the left conical surface of the fixed block and the outer diameter of the right elastic pressing sheet are both larger than the outer diameter of the bearing, the inner diameter of the stop ring can be ensured to be larger than the outer diameter of the bearing during installation, and the outer diameter surface of the bearing is prevented from being scratched.

Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in FIG. 3, a snap ring mounting device for a single-row cylindrical roller bearing for preventing the outer diameter from being scratched, wherein a fixed block 1 of the snap ring mounting device is a cone with a small upper part and a large lower part; the whole fixed block is an irregular cone, the top view of the fixed block is shown in figure 4, and the upper end surface of the fixed block is provided with three uniformly distributed positioning holes 10; the inner hole of the fixed block 1 and the fixed block are eccentrically arranged, so that a structure that the maximum diameter of the left conical surface of the fixed block is larger than the outer diameter of the bearing, and the maximum outer diameter of the right conical surface of the fixed block is smaller than the outer diameter of the bearing is formed; two bolt holes 11 are formed in the right conical surface and can be used for adjusting the angle of the elastic pressing sheet so as to facilitate installation; the lower end of the fixed block is provided with a positioning shaft in clearance fit with the bearing inner ring; an elastic pressing sheet 9 is arranged on the right conical surface of the fixed block; the elastic pressing sheet 9 is obliquely arranged, and the lower end of the elastic pressing sheet is positioned outside the end face of the bearing outer ring; the stop ring mounting device is also provided with a press mounting ring which is convexly and concavely buckled with the fixed block; the press-fitting ring is provided with a press-fitting plate positioned above the fixing ring; the lower part of the press-fitting plate has a ring-shaped structure for press-fitting onto the snap ring.
Referring to fig. 2, the stop ring 3 is in the shape of a ring with a break, and has a certain elastic deformability.
The press mounting ring is provided with a wedge-shaped block protruding downwards on the press mounting plate, and a wedge-shaped groove buckled with the wedge-shaped block is formed in the fixed block.
When the bearing outer ring locking device is installed, as shown in fig. 5, one side of the locking ring is clamped at the notch of the bearing outer ring locking ring, and the other end of the locking ring is placed on the elastic pressing sheet of the positioning block. After the stop ring is placed, the press-fitting ring is held by a hand to be pressed downwards, and when the conical positioning pin on the press-fitting ring is completely matched with the conical hole on the fixing block, the stop ring is installed. Because the large outer diameter of the left conical surface of the fixed block and the outer diameter of the right elastic pressing sheet are both larger than the outer diameter of the bearing, the inner diameter of the stop ring can be ensured to be larger than the outer diameter of the bearing during installation, and the outer diameter surface of the bearing is prevented from being scratched.
