Description

Bearing angle backlash detector

Technical field:

The present invention relates to technical field of bearings, more specifically to a kind of equipment detected the angle play of bearing.

Background technology:

When angle play refers to that bearing inner race is subject to shearing force, the inner ring of bearing is relative to the angle of inclination between outer ring, general bearing manufacturer is not detected this index now, but some bearing is before dispatching from the factory, the angle play amount of client to bearing has specific requirement, this just requires that we measure the angle play of bearing, so just need to design a kind of bearing angle backlash detector.

Summary of the invention:

Object of the present invention is exactly the deficiency for prior art, and a kind of bearing angle backlash detector is provided, it can test bearing inner ring relative to the angle play amount of bearing outer ring under certain shearing force, clean out inappropriate angle play bearing products, guarantee the quality and prestige of Production of bearing producer.

Technology solution of the present invention is as follows:

Bearing angle backlash detector, comprise clock gauge, be placed with detection dish on the table, detection dish has the detection center hole of circular hole, detecting center hole is the hole with detection dish step, detecting pallet is placed on detection dish step, the detection tray center hole of detection pallet has and detects pallet step, and bearing to be detected is placed in and detects on pallet step;

Platen is fixed by screws in and detects on pallet, and the outer ring of bearing to be detected is clamped in platen and detects between pallet step;

Test rod sleeve, in the inner ring of bearing to be detected and the center pit of platen, test rod forms annular groove, and the lower end of test rod is placed on worktable;

The collar to be enclosed within test rod and to be placed in annular groove, and bracing wire one end is fixed on the collar, the other end is fixed on balancing weight, and pulley is arranged on pole, and pulley is walked around in bracing wire, and the lower end of pole is fixing on the rotating pan, and the base of rotating disc is fixed on detection dish;

The detection contact of clock gauge contacts with test rod, and clock gauge is fixed on Bracket for Inspection, and Bracket for Inspection is fixed on detection dish.

The bottom of described Bracket for Inspection is fixed on carrier base, and carrier base is fixed or is placed on detection dish.

Described platen forms " 8 " font screw rod through hole.

Beneficial effect of the present invention is:

It can test bearing inner ring relative to the angle play amount of bearing outer ring under certain shearing force, clean out inappropriate angle play bearing products, guarantee the quality and prestige of Production of bearing producer.

In figure: 1, clock gauge; 2, worktable; 3, detection dish; 4, pallet is detected; 5, platen; 6, test rod; 7, the collar; 8, bracing wire; 9, balancing weight; 10, pulley; 11, pole; 12, Bracket for Inspection; 13, carrier base; 14, rotating disc.

Embodiment:

Embodiment: see shown in Fig. 1 to 5, bearing angle backlash detector, comprise clock gauge 1, worktable 2 is placed with detection dish 3, detection dish 3 has the detection center hole 31 of circular hole, detects center hole 31 for having the hole of detection dish step 32, detects pallet 4 and is placed on detection dish step 32, the detection tray center hole 41 of detection pallet 4 having detection pallet step 42, bearing A to be detected is placed on detection pallet step 42;

Platen 5 is fixed by screws in and detects on pallet 4, and the outer ring of bearing A to be detected is clamped in platen 5 and detects between pallet step 42;

Test rod 6 sleeve, in the inner ring of bearing A to be detected and the center pit of platen 5, test rod 6 forms annular groove 61, and the lower end of test rod 6 is placed on worktable 2;

The collar 7 to be enclosed within test rod 6 and to be placed in annular groove 61, bracing wire 8 one end is fixed on the collar 7, the other end is fixed on balancing weight 9, and pulley 10 is arranged on pole 11, and pulley 10 is walked around in bracing wire 8, the lower end of pole 11 is fixed on rotating disc 14, and the base of rotating disc 14 is fixed on detection dish 3;

The detection contact 1a of clock gauge 1 contacts with test rod 6, and clock gauge 1 is fixed on Bracket for Inspection 12, and Bracket for Inspection 12 is fixed on detection dish 3.

The bottom of described Bracket for Inspection 12 is fixed on carrier base 13, and carrier base 13 is fixing or be placed on detection dish 3.

Described platen 5 forms " 8 " font screw rod through hole 51.

Principle of work: see shown in Fig. 1,2, test rod 6 is subject to the pulling force to the right of the weight of balancing weight 9, this pulling force is applied on the inner ring of bearing A to be detected by test rod 6, so the inner ring of bearing A to be detected just creates an angle play amount relative to the outer ring of bearing A to be detected, this amount can be learnt according to the data variation on clock gauge 1.

When clock gauge 1 does not add balancing weight 9 in bracing wire 8, just contact with test rod 6 and produce a reading, after bracing wire 8 adds balancing weight 9, clock gauge 1 can produce second reading, the difference of these two readings just can be converted into the angle play amount of bearing.

Test rod 6 chooses the test rod 6 close with the inner ring internal diameter of bearing A to be detected as far as possible.

" 8 " font screw rod finds when being convenient to gib screw through hole 51 and detects bolt apertures corresponding on pallet 4.

The lower end of pole 11 is fixed on rotating disc 14, and the base of rotating disc 14 is fixed on detection dish 3; Pole 11 can be rotated like this and detect angle play in bearing A all directions to be detected.
