Abstract
The utility model discloses a kind of speed limit bearing, comprise bearing inner race, bearing outer ring, centrifugal film, spring, friction plate, described friction plate is fixed on centrifugal film, centrifugal film is connected with bearing inner race by connecting bolt, and spring connects centrifugal film and bearing inner race and centrifugal film and bearing inner race strained.Speed limit bearing of the present utility model carries out speed limit by bearing speed limiting device to bearing, and available protecting bearing can not damage because rotating speed is excessive; By bearing speed limiting device, speed limit is carried out to axle, when driving mechanism rotating speed is abnormal, the equipment of each gear stage is protected, equipment can not be damaged because of the rotating speed of uprushing.
Description
Technical field
The utility model belongs to mechanical field, specifically a kind of speed limit bearing.
Background technique
The bearing generally used at present does not limit rotating speed functions, and the defect that the bearing of this structure exists is: (1) does not have restricting means to rotating speed, and bearing easily damages; (2) time for Multi-stage transmission, when the superior and the subordinate's rotating speed is excessive, can not protect the driving mechanism of other grades.
Model utility content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of speed limit bearing, comprise bearing inner race, bearing outer ring, centrifugal film, spring, friction plate, described friction plate is fixed on centrifugal film, centrifugal film is connected with bearing inner race by connecting bolt, and spring connects centrifugal film and bearing inner race and centrifugal film and bearing inner race strained.
Further, described bearing inner race and bearing outer ring are respectively equipped with inner ring keyway and outer ring keyway.
Speed limit bearing of the present utility model carries out speed limit by bearing speed limiting device to bearing, and available protecting bearing can not damage because rotating speed is excessive; By bearing speed limiting device, speed limit is carried out to axle, when driving mechanism rotating speed is abnormal, the equipment of each gear stage is protected, equipment can not be damaged because of the rotating speed of uprushing.
Accompanying drawing explanation
Fig. 1 is the structural representation of speed limit bearing of the present utility model;
Fig. 2 is the side view of this speed limit bearing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, speed limit bearing of the present utility model, comprise bearing inner race 1, bearing outer ring 2, centrifugal film 3, spring 4, friction plate 5, friction plate 5 is fixed on centrifugal film 3, centrifugal film 3 is connected with bearing inner race 1 by connecting bolt 6, and spring 4 connects centrifugal film 3 with bearing inner race 1 and centrifugal film 3 and bearing inner race 1 to be strained.Bearing inner race 1 and bearing outer ring 2 are respectively equipped with inner ring keyway 7 and outer ring keyway 8.
When bearing inner race 1 rotating speed reaches limit value, centrifugal force is greater than spring tension, and centrifugal film 3 throws away, and the friction plate 5 be fixed on centrifugal film 3 contacts with bearing outer ring 2 and produces frictional force and reduce bearing inner race 1 rotating speed.Inner ring keyway 7 and outer ring keyway 8, for by this speed limit bearing axial limiting, increase the steadiness that bearing is fixing.
Claims (2)
1. a speed limit bearing, comprise bearing inner race (1), bearing outer ring (2), centrifugal film (3), spring (4), friction plate (5), it is characterized in that: described friction plate (5) is fixed on centrifugal film (3), centrifugal film (3) is connected with bearing inner race (1) by connecting bolt (6), and spring (4) connects centrifugal film (3) with bearing inner race (1) and centrifugal film (3) and bearing inner race (1) to be strained.
2. speed limit bearing as claimed in claim 1, is characterized in that: described bearing inner race (1) and bearing outer ring (2) are respectively equipped with inner ring keyway (7) and outer ring keyway (8).
