Abstract

The utility model discloses a radial runout detector for an inner race of a bearing and relates to an inspection tool. The radial runout detector comprises a bearing support part and a detecting part and is characterized in that the bearing support part comprises a central spindle (3), tips (2) and a support rod (9); the central spindle (3) is matched with the inner race of the measured bearing (4); the tips (2) are arranged at the two ends of the central spindle (3) and used for fixing the central spindle (3); the support rod (9) is used for supporting the tips and arranged in a sliding groove of a base (7); the detecting part comprises a dial indicator (5) provided with an indicator frame (6); the indicator frame (6) is arranged on the base (7); a pointer of the dial indicator (5) is pressed on an outer race of the measured bearing (4); and the detector is suitable for a batch production line of the bearing and can improve the inspection efficiency under the premise that the inspection accuracy is guaranteed.

Description

A kind of bearing inner race diameter run-out detector

Technical field

The utility model relates to a kind of instruments of inspection, is specifically related to a kind of bearing inner race diameter run-out detector.

Background technology

In the Production of bearing enterprise, the link that is absolutely necessary of the check after bearing assembling is finished.The diameter run-out, inner ring datum end face that the main Interventions Requested of bearing comprise end-play, end-play, complete bearing enclose to the beating of internal diameter, external diameter surface bus to the degree of tilt variation of datum end face, complete bearing enclose end face beating and vibration etc. to raceway.Wherein, the diameter run-out of complete bearing inner race is too big, influences the running accuracy of bearing and causes noise.

Mostly in the Production of bearing enterprise, very simple and easy to the detection of the diameter run-out of complete bearing inner race, as bearing is placed on the platform, with the equidistant retaining of three contour pads in bottom, outer ring, fixedly outer ring; Indicating gauge is beaten at the inner ring bore area, and near the inner ring raceway middle part, inner ring rotates a circle, and the maximum difference with least count of indicating gauge promptly is recorded as the diameter run-out of inner ring.This traditional check system will rely on workman's experience, and checkability is not high, and testing accuracy is limited.

Summary of the invention

For overcoming the deficiency in the background technology, the invention technical matters to be solved provides a kind of bearing inner race diameter run-out detector, and this detector is applicable to the bearing production line of batch and improves checkability under the prerequisite that guarantees testing accuracy.

For achieving the above object, following technical scheme is adopted in the invention:

A kind of bearing inner race diameter run-out detector comprises the bearings parts, detection part; Described bearings parts comprise the mandrel that cooperates with bearing inner race, are arranged on the top of mandrel two ends fixed central spindle and support top support bar, and described support bar is arranged in the chute of pedestal; Described detection part comprises the clock gauge that is provided with dial framework, and described dial framework is arranged on the pedestal; The pointer of described clock gauge is pressed on the described bearing outer ring.

Be better implement the invention, described bearing inner race and mandrel form transition fit.

Be better implement the invention, described top by being arranged on the rotation hand wheel adjustment on the support bar.

Be better implement the invention, described bearing outer ring is supported by the adjustable clamp that is arranged on the pedestal.

Owing to adopted technique scheme, the invention to have following beneficial effect:

1, this detector makes it to be adapted to different bearings by adjusting the position of support bar in the pedestal chute and the position of adjusting clock gauge adjuster bar.

2, during check bearing, only need bearing is placed on the mandrel,, avoided that need be provided with the loaded down with trivial details of testing conditions separately to each bearing in the prior art, guaranteed accuracy of detection in the time of efficient detection by the structural orientation of detector itself.

Description of drawings

Fig. 1 is the structural representation of the invention;

Among the figure: 1, rotation hand wheel; 2, top; 3, mandrel; 4, measured bearing; 5, clock gauge; 6, dial framework; 7, pedestal; 8, set screw; 9, support bar; 10, set screw; 11, adjustable clamp; 12, set screw.

Embodiment

In conjunction with Fig. 1, the bearing inner race diameter run-out detector of the invention is that bearings parts, detection part are set on pedestal 7; Described bearings parts are that measured bearing 4 inner rings are cooperated with mandrel 3, and the mandrel two ends are fixing by top 2, and top 2 are arranged on the support bar 9, and support bar 9 is arranged in the chute of pedestal 7.Described detection part is the clock gauge 5 that is provided with dial framework, and clock gauge dial framework 6 is arranged on the pedestal 7; The pointer of clock gauge is pressed on measured bearing 4 outer rings.The location is supported by the adjustable clamp 11 that is arranged on the pedestal 7 in measured bearing 4 outer rings, and adjustable clamp 11 is fixed on the pedestal 7 by set screw 12.

During detection, measured bearing 4 is contained on the mandrel 3, and mandrel 3 is contained between two top 2, make top 2 fixed central spindles 3 in the position of chute by regulating support bar 9, fastening adjustment screws 10 afterwards; Adjust the movable adjuster bar of clock gauge the clock gauge pointer is beaten at the middle part of measured bearing outer ring raceway, press table 0.5mm, fastening adjustment screws 8.The location is supported by adjustable clamp 11 in the outer ring, keeps static, is rotatably provided in rotary handle 1 on the support bar 9, and mandrel 3 is rotated a circle, and the difference of the minimum and maximum reading of clock gauge 5 is the diameter run-out of bearing inner race.
