The present invention relates generally to a massaging machine, and more particularly to a steering mechanism of the massaging machine.
The conventional steering mechanism of the massaging machine comprises a gear, confining slot, insertion pin, fly wheel, arresting gear, etc. The conventional steering mechanism is complicated in construction and is therefore not cost-effective, thereby resulting in high production cost of the massaging machine.
The primary objective of the present invention is to provide a massaging machine with a cost-effective steering mechanism comprising a shaft, a drive gear, a driven seat, an auxiliary gear, and a unidirectional bearing. The drive gear is mounted on the shaft and is engaged with a worm driven by a motor. The auxiliary gear is fastened with the driven seat which is mounted on the shaft in conjunction with the unidirectional bearing. The drive gear is provided with a master gear which is linked with a slave gear of the massaging device of the massaging machine by a chain. The auxiliary gear is engaged with a transmission gear, so as to enable the massaging device to move in a reciprocating manner. The shaft of the steering mechanism of the present invention is formed of a core and a wear-resistant sleeve fitted over the core. The drive gear and the unidirectional bearing of the driven seat are mounted on the wear-resistant sleeve of the shaft.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
As shown in
The driven gear 40 is provided with a center hole 401 and a master gear 41. The center hole 401 is used to mount the drive gear 40 on the shaft 30 such that the drive gear 40 is engaged with a worm 51 driven by a motor 50, and that the master gear 41 is linked with a slave gear 42 by a chain 43 which is engaged with a gear 44 of two massaging members 21 of the massaging device 20.
The driven seat 60 is provided with an auxiliary gear 61, and a fitting hole 601 by which the driven seat 60 is mounted on the shaft 30 such that the auxiliary gear 61 is engaged with a transmission gear 62 which actuates a bidirectional threaded rod 65 via two sector gears 63 and 64. As the bidirectional threaded rod 65 is actuated, a mounting seat 22 of the massaging device 20 is driven to move in a reciprocating manner.
The steering mechanism of the present invention is characterized by the shaft 30 and the driven seat 60. The shaft 30 is formed of a core 31 and a wear-resistant sleeve 32 fitted over the core 31. The driven seat 60 is provided in the fitting hole 601 thereof with a unidirectional bearing 70. The drive gear 40 is mounted on the wear-resistant sleeve 32 of the shaft 30, whereas the driven seat 60 is mounted on the wear-resistant sleeve 32 of the shaft 30 in conjunction with the unidirectional bearing 70.
