SU513235A1 - Device for determining the effect of mounting errors on kinematic precision and smoothness of gears - Google Patents

Description

The drawing shows a schematic diagram of the proposed device comprising a frame 1, a driving shaft 2, a friction disk 3 mounted thereon and a measuring wheel mandrel 4, a measuring wheel 5, a driven shaft composed of three parts. The first part contains a fixed mandrel 6, a friction disk 7, a spherical support 8. The second part contains a spherical hinge 9, op-. equal to 10, controlled wheel 11, conical sleeve 12. The third part contains a mandrel 13, in the lower part of which a strainer 14 and a current collector 15 are fixed, a spherical sleeve 16,

The device works as follows. zom.

The drive shaft 2 receives a rotational movement from the electric drive (not shown). Disks 3 and 7 are frictionally interconnected. Wheels 5 and C are in single-profile gearing.

In the absence of face beats, the geometrical axes of all three parts constitute one common vertical axis.

Making the face beats of a given value due to the tilting of the axis of the second part relative to the center of the hinge 9 using the micrometer head 17 changes the relative position of the geometrical axes of the second and third parts of the driven shaft and causes a misalignment of the rotational movement of the friction disk 7 relative to the same movement of the wheel C (with parallel axes of disks 3 and 7). Fixing the position of the axis of the second part of the shaft is carried out by interacting the conical and spherical mating surfaces of the sleeves 12 and 16, as well as by clamping the spherical hinge 9 by pressing the threaded connection between the sleeve 12 and the mandrel 10.

 The inclination of the axis of the second part relative to the axis of the first and third parts of the shaft is reproduced by displacing the auxiliary spherical hinge 18 using a micrometric reading head 17, which is directly involved

in measurements of kinematic fit in the presence of face beats, it does not lritgy, but serves only to introduce and count the errors of a given magnitude, after which it is removed from the interaction with the second part of the shaft.

Further, the kinematic accuracy and smoothness of the engagement of a pair of wheels 5 and 11 is measured in the same way as in known devices.
