Abstract
A testing apparatus includes a crosshead and a head assembly. The head assembly includes a head cover having an interior volume. An electric actuator, controls and other electric components are located within the interior volume, wherein the motor, controls and other electric components generates heat when energized. A divider within the interior volume separates a first volume from a second volume. The first volume includes the heat generating electric motor, controls and electric components and the second volume contains substantially no heat generating components. The head assembly includes at least one fan within the second volume that draws cool air from outside the head cover and forces the cool air through the second volume and into the first volume to remove heat.
Claims19
A head assembly for a testing apparatus having a crosshead, the head assembly comprising:
- a head cover having an interior volume;
- an electric actuator within the interior volume, wherein the electric motor generates heat when energized;
- control and electric components within the interior volume wherein the control and electric components generate heat when energized;
- a divider within the interior volume that separates a first volume from a second volume, wherein the first volume includes the heat generating electric actuator and the heat generating control and electric components and the second volume contains substantially no heat generating components;
- at least one fan within the second volume wherein the at least one fan draws cool air from outside the head cover and forces the cool air through the second volume and into the first volume wherein the cool air removes heat generated by the electric actuator and the control and electric components.
A testing apparatus comprising:
- a base;
- spaced apart left and right support post coupled to the base;
- a crosshead slidably attached to the spaced apart left and right support posts wherein the crosshead is securable in a selected location;
- a head cover attached to the crosshead and having an interior volume;
- an electric actuator within the interior volume, wherein the electric motor generates heat when energized;
- control and electric components within the interior volume wherein the control and electric components generate heat when energized;
- a divider within the interior volume that separates a first volume from a second volume, wherein the first volume includes the heat generating electric actuator and the heat generating control and electric components and the second volume contains substantially no heat generating components;
- at least one fan within the second volume wherein the at least one fan draws cool air from outside the head cover and forces the cool air through the second volume and into the first volume wherein the cool air removes heat generated by the electric actuator and the control and electric components.
A head assembly for a testing apparatus having a crosshead, the head assembly comprising:
- a head cover having an interior volume;
- an electric actuator comprising an armature assembly having a first end and a second end wherein the armature moves within the head cover;
- and
- an end cap attached to a distal end of the armature and movable with the armature wherein the end cap comprises vents that allow air to flow therethrough as the armature moves within the head cover and crosshead and prevents an air cushion that could adversely affect the performance of the testing apparatus.
