20090013502 | Adjustable Handlebar Assembly for a Stand - An adjustable handlebar assembly for a stand comprises a handlebar and a positioning assembly. The handlebar is rotatably mounted on the stand, and the positioning assembly serves to position the handlebar. The handlebar can be rotated to adjust its operation angle and can be positioned by the positioning assembly after rotating to a desired angle, so that the user can adjust the operation angle of the handlebar according to his own stature and habit, thus enhancing the convenience of use. | 01-15-2009 |
20090016814 | Connecting Device for an Actuator - A connecting device for an actuator comprises two actuators, a connecting assembly and a motor. Mandrels of the actuators are located correspondingly to each other, and lower ends of the actuators are connected to each other. A connecting assembly is provided for connecting the mandrels of the actuators, such that the actuators are combined with each other. A motor serves to drive the mandrel of one of the actuators, enabling the actuators to extend or retract simultaneously. Thereby, one motor can drive two actuators simultaneously, thus obtaining a double travel length by using only a single actuator, so the structure is simple and the cost is low, and the connecting device for an actuator is easy to assemble. | 01-15-2009 |
20090032335 | Bearing-Lubricating Structure for a Direct Drive Torque Motor - A bearing-lubricating structure for a direct drive torque motor comprises a body, a direct drive torque motor, a main shaft, a bearing assembly, an adjustment nut and an oil-filling assembly. The bearing assembly includes an assistant roller bearing which is positioned against the rear cover, the main shaft and the adjustment nut. The rear cover is defined with a lubrication oil piping, which is communicated to the assistant roller bearing and communicated to an annular lubrication space located between the rear cover and the adjustment nut. The oil-filing assembly is mounted on an open end of the lubrication oil piping. Thereby, with the abovementioned simplified structure, the main shaft can be lubricated, and the maintenance cost can be reduced. | 02-05-2009 |
20090032336 | Main Shaft-Lubricating Structure for a Direct Drive Torque Motor - A main shaft-lubricating structure for a direct drive torque motor comprises a body, a direct drive torque motor, a main shaft, a bearing assembly, an adjustment nut and a brake assembly. The main shaft cooperates with the adjustment nut to fix the torque motor, the bearing assembly and the body. The bearing assembly utilizes the main bearing and the brake assembly to be supported between the body and the main shaft. The brake assembly and the body are defined with a first lubrication oil piping and a second lubrication oil piping, respectively. The first lubrication oil piping is communicated with the main bearing, and the second lubrication oil piping is communicated between the brake assembly and the main shaft. Thereby, with the abovementioned simplified structure, the main shaft can be lubricated, and the maintenance cost can be reduced. | 02-05-2009 |
20090032363 | Brake Structure for a Main Shaft of a Direct Drive Torque Motor - A brake structure for a main shaft of a direct drive torque motor comprises a body, a direct drive torque motor, a main shaft and a brake assembly. The main shaft is provided for fixing the torque motor and the body, and the brake assembly is mounted between the body and the main shaft. An annular brake oil room of the brake assembly is positioned against the main shaft, and the brake seat subassembly has a thinner brake deformation wall formed between the annular brake oil room and the main shaft. The annular brake oil room utilizes its high pressure caused deformation to the brake deformation wall, thus achieving a braking effect by pressing the main shaft. Thereby, the present invention is easy to assemble, and not only can stop the main shaft quickly, but also has a greater locking force. | 02-05-2009 |
20090033273 | Direct Drive Torque Motor - A direct drive torque motor comprises: a body, a direct drive torque motor, a main shaft, a bearing assembly, a brake assembly, a cooling assembly, and a position-sensing assembly. The bearing assembly is used to position the main shaft in the direct drive torque motor and the body. The brake assembly is disposed between the body and the main shaft. The cooling assembly is located in the body to cool the torque motor. The position-sensing assembly is mounted on the body for sensing the rotation of the main shaft and then controls the drive of the direct drive torque motor. With above arrangements, the direct drive torque motor can be used on various machines that need to rotate to perform various angle control, rotation control and accuracy control, it can improve the life and the modular application of the product. | 02-05-2009 |
20100116073 | Actuator with an anti-loose structure - An actuator with an anti-loose structure comprises an actuator and an anti-loose structure. The actuator includes a first tube, a second tube and a drive assembly. The first tube is movably mounted on the second tube, and the drive assembly is drivingly connected to the first and the second tubes and provided with a drive gear connected to a power source. The drive assembly obtains the power through the drive gear to drive the second tube to life and descend with respect to the first tube. The anti-loose structure includes a first limit member and a second limit member that are both disposed on the drive screw of the drive assembly. The first limit member and the second limit member are respectively located at two ends of the drive gear to for avoiding the uncontrollable movement of the drive gear, which is likely to affect extending/retracting movement of the actuator. | 05-13-2010 |
20100122594 | Actuator with self-locking assist device - An actuator with self-locking assist device comprises an actuator and a self-locking assist device, wherein the self-locking assist device is disposed at one end of the actuator, and the friction force between the self-locking assist device and the actuator is used to improve the self-locking capability of the actuator, thus preventing the uncontrollable movement of the actuator caused by the influence of the load carried. | 05-20-2010 |
