Push-pull chain drive door operator system |
摘要 |
A push-pull chain garage door operator system includes a drive module and an elongated guide rail for a push-pull chain connected to a carriage assembly mounted on the guide rail. The chain is engaged with a sprocket mounted on a generally rectangular plate-like molded plastic support member which includes a serpentine idle chain storage slot formed therein. The support member is releasably connected to a stamped metal frame plate for covering the storage slot and supporting the drive module. The bottomwall of the support member supports a right angle speed reduction drive unit connected to a drive motor retained in a cradle formed by an integral boss on the support member. The motor and a starting capacitor therefor are retained in respective cradle portions of the boss by a removable retaining strap. A control circuit board is mounted on the underside of the support member and a two-part shroud for the operator mechanism is releasably secured to the frame plate.
