Abstract
A mandrel for supporting a roller bearing by a cylindrical roller relates to a mandrel for a bearing, wherein a protruding ring (5) is arranged on the outer edge surface of one end of an axis (3), an annular groove (6) is arranged on the outer edge surface of the protruding ring (5), an annular half groove (4) is arranged at the end part of the outer edge surface of the protruding ring (5) close to the other end of the axis (3), connecting rods (1) are respectively arranged at two ends of the axis (3), half grooves (2) are respectively arranged at the end parts of the two connecting rods (1), and a clamp spring (8) is sleeved in the annular groove (6); the utility model discloses a set up the axle center into one end and cup jointed outstanding ring, set up the annular groove on outstanding ring to set up the jump ring in the annular groove, stretch into the outer lane with the axle center, played the outer lane and stabilized the rotation on the axle center and increased the bearing capacity and avoided cylindrical roller to advance the purpose of dust.
Description
Technical Field
The utility model relates to a dabber for the bearing especially relates to a dabber that supplies cylindrical roller supporting roller bearing to use.
Background
The bearing is an important part in the modern mechanical equipment, and has the main functions of supporting the mechanical rotating body, reducing the friction coefficient in the movement process of the mechanical rotating body and ensuring the rotation precision of the mechanical rotating body; when a common cylindrical roller bearing is used on a plate bending machine, the common cylindrical roller bearing can only bear a small axial load, in practical application, due to misalignment error between a shaft and a bearing seat, the bearing can bear an axial force generated by unbalance loading and an impact shock load borne during working, when the axial and impact loads borne by the bearing are overlarge relative to those of the cylindrical roller bearing, the flange of the bearing can be damaged, so that the bearing is damaged and failed early, inestimable economic loss can be caused to a host factory due to increase of downtime and plate bending quality problems, and in order to avoid the defect, a supporting roller bearing is required to be used, wherein a mandrel for the supporting roller bearing needs to play a large bearing role, and the service life and the bearing capacity of the supporting roller bearing can be effectively prolonged by improving the mandrel.
Disclosure of Invention
In order to overcome not enough among the background art, the utility model discloses a supply dabber that cylindrical roller supporting roller bearing used sets up the axle center into one end and has cup jointed outstanding ring through having set up the axle center, sets up the annular groove on outstanding ring to set up the jump ring in the annular groove, stretch into the axle center in the outer lane, played the outer lane and stably rotated the purpose that increases the bearing capacity and avoid cylindrical roller to advance the dust on the axle center.
In order to realize the purpose, the utility model adopts the following technical scheme:
the utility model provides a supply dabber that cylindrical roller supporting roller bearing used, includes axle center and jump ring, is equipped with outstanding ring at the outer fringe face of axle center one end, is equipped with the annular groove at the outer fringe face of outstanding ring, is equipped with annular half groove at the outer fringe face tip of the outstanding ring that is close to the axle center other end, is equipped with the connecting rod respectively at the both ends in axle center, is equipped with half groove respectively at the tip of two connecting rods, and the jump ring cup joints in the annular groove.
The mandrel for supporting the roller bearing by the cylindrical roller is provided with a joint on the clamp spring.
The edge of the end parts of the two connecting rods of the mandrel for supporting the roller bearing by the cylindrical roller is respectively provided with chamfer transition.
Since the technical scheme is used, the utility model discloses following beneficial effect has:
the mandrel for the cylindrical roller supporting roller bearing, provided by the utility model, has the advantages that the shaft center is set to one end, the protruding ring is sleeved, the annular groove is arranged on the protruding ring, the snap spring is arranged in the annular groove, and the shaft center is stretched into the outer ring, so that the purposes that the bearing capacity is increased by stably rotating the outer ring on the shaft center and the cylindrical roller is prevented from entering dust are achieved; the utility model relates to a novel unique, bearing capacity is strong, the operation is stable, has very big market spreading value.

fig. 2 is a schematic structural view of the axle center of the present invention.
In the figure: 1. a connecting rod; 2. a half groove; 3. an axis; 4. an annular half groove; 5. a projecting ring; 6. an annular groove; 7. a joint; 8. and a clamp spring.
Detailed Description
The present invention will be explained in more detail by the following examples, which are not intended to limit the invention, and the purpose of disclosing the invention is to protect all the changes and improvements that come within the scope of the invention;
combine attached figure 1 or 2 supply dabber that cylindrical roller supporting roller bearing used, including axle center 3 and jump ring 8, be equipped with outstanding ring 5 at the outer fringe face of 3 one ends in axle center, be equipped with annular groove 6 at the outer fringe face of outstanding ring 5, be equipped with annular half groove 4 at the outer fringe face tip of the outstanding ring 5 that is close to the 3 other ends in axle center, both ends in axle center 3 are equipped with connecting rod 1 respectively, tip at two connecting rod 1 is equipped with half groove 2 respectively, the border department of 1 tip of two connecting rods sets up the chamfer transition respectively, jump ring 8 cup joints in annular groove 6, be equipped with on jump ring 8 and connect 7.
Implement supply dabber that cylindrical roller supporting roller bearing used, during the use, stretch into supporting roller bearing's outer lane with axle center 3, set up cylindrical roller between axle center 3 and outer lane, cup joint jump ring 8 in annular groove 6, cup joint the fender ring at the other end in axle center 3, utilize two half grooves 2 respectively with the tip of two connecting rods 1 and even on the veneer reeling machine, the outer lane outer wall contact of utilization outer lane needs the board of book, can realize the purpose of the stable board of rolling up of cylindrical roller supporting roller bearing.
The part of the utility model not detailed is prior art.
