| 发明名称 | Elevator machine frame with noise reducing configuration | ||
| 摘要 | An exemplary elevator machine frame includes a plurality of support surfaces configured to support at least one of a motor or a brake. A plurality of arms between the support surfaces maintain a desired alignment of support surfaces. At least one of the arms has a first cross section taken transverse to a longitudinal direction along a length of the arm at a first longitudinal location on the arm. That same arm has a second, different cross section at a second, different longitudinal location on the arm. | ||

| 主权项 | 1. An elevator machine frame, comprising: a plurality of support surfaces configured to support at least one of a motor or a brake; a plurality of arms between the support surfaces and maintaining a desired alignment of the support surfaces, at least one of the arms having a first cross section taken transverse to a longitudinal direction along a length of the at least one arm at a first longitudinal location on the at least one arm anda second, different cross section at a second, different longitudinal location on the at least one arm;wherein the first and second cross sections are taken at the same angle relative to the longitudinal direction; andwherein the cross section of the at least one arm progressively varies between the first second locations. | ||
