Problems solved by technology

[0004] In fact, since in the above-mentioned type of encoder the support part is made of metal and the control part is made of magnetic rubber, deformations due to assembly and operation related to the support part often affect the control part to some extent , which in extreme cases will cause the control part to break

Embodiment Construction

[0010] refer to figure 1 and 2 , reference numeral 1 designates as a whole an encoder for a rolling contact bearing 2 .

[0011] The bearing 2 has an axis of rotation A and comprises an outer rotating race 3 provided with an end outlet 4 obtained corresponding to the outer axial edge 5 of the race 3 itself.

[0012] The encoder 1 includes a support housing 10 mounted on the outlet 4 and a control race 20 integrated with the support housing 10 to read the angular velocity of the race 3 .

[0013] The supporting shell 10 assumes the form of a ring coaxial to the axis A and is made of a plastic / rubber material or an elastomeric material, such as thermoplastic rubber, with a stiffness of 1 . The casing 10 includes a basic cylindrical body 11 and two annular edges 12, which are arranged on the sides of the body 11 and integrated with the body 11, and which are oriented toward the outer side of the body 11. Extending radially, the body 11 itself defines an annular support 13 for ...

Abstract

Encoder for rolling contact bearings provided with a support portion which is interference-mounted onto a rotating race of the rolling contact bearing, and with a control portion which is integral with the support portion in order to emit a signal in relation to the angular speed of the rotating race; the support portion presenting a rigidity which is less than that of the control portion in order to absorb any eventual deformation which might be due to assembly or functioning.

Description

technical field [0001] The invention relates to an encoder for a rolling contact bearing. Background technique [0002] In the field of rolling contact bearings, it is known to mount an encoder on the rotating race of the rolling contact bearing to read the angular velocity of the rotating race itself, the encoder generally comprising a support part and a control part, the support part interfering with Mounted on the rotating race and made of metal material, the control part is integrated with the support part and made of magnetic rubber. [0003] The reduction in the space available for mounting the encoder also necessitates a reduction in the thickness associated with the support part and the control part, with attendant disadvantages due to the difference in rigidity of these two parts. [0004] In fact, since in the above-mentioned type of encoder the support part is made of metal and the control part is made of magnetic rubber, deformations due to assembly and operatio...
