Problems solved by technology

When using the grease coating method, if the grease is not kept attached to the tooth surface of the worm and the worm gear, the grease will be squeezed out of the tooth surface due to the meshing of the worm and the worm gear. When the pair rotates at high speed, the grease will fly out from the tooth surface, which may cause the burning of the worm pair and cause failure

Embodiment Construction

[0053] refer to Figure 1~3 Examples of the present invention will be described. However, the present invention is not limited to this embodiment.

[0054] figure 1 The gear unit 10 shown has a motor M and a housing 12 to which the motor M is coupled. A worm gear 20 and a parallel gear 30 are accommodated inside the housing 12 . The present invention can also be applied to a gear device consisting only of a worm gear pair, but for convenience, a gear device 10 having a worm gear pair 20 and a parallel gear 30 will be described.

[0055]Since the input shaft 14 of the motor M is connected to the worm 22 of the worm gear pair 20 , the torque from the motor M is transmitted to the worm 22 and then to the worm gear 24 meshing with the worm 22 through the meshing portion 26 . Furthermore, the torque transmitted to the turbine wheel 24 is transmitted to the input parallel gear 32 provided on the same axis as the intermediate shaft 18 through the intermediate shaft 18 rotatably p...

Abstract

The invention provides a gear device which, by virtue of a simple structure, can maintain lubricant even in high-speed rotation of a turbine worm pair and can prevent oil leakage. The gear device (10)is configured to fill lubricating grease continuously among an engagement part (26) of the turbine worm pair (20), a tooth surface of the turbine (24) and a face (25) opposite to the turbine tooth surface and between one side face of the turbine (24) and a face (27) opposite to the side face of the turbine, thus by virtue of the simple structure, even in high-speed rotation of the turbine worm pair (20), scattering of lubricating grease can be suppressed, lubrication can be maintained, and since the lubricating grease does not need to be filled in a whole shell (12), oil leakage can be prevented.

Description

technical field [0001] The present invention relates to a technique for improving the lubricity of a worm gear and preventing oil leakage in a gear device having a worm gear. Background technique [0002] In a gear unit having a worm gear, it is necessary to lubricate the meshing between the worm of the worm gear and the worm gear for smooth operation. In order to lubricate a worm gear pair, there are an oil bath method and a grease bath method in which a worm or a turbine is immersed in lubricating oil or grease. However, these methods are not suitable as gear units in fields where oil leakage is likely, for example, gear units used in conveying devices related to food and clothing, because of the possibility of oil leakage. [0003] On the other hand, in order to prevent oil leakage, there is a grease application method in which hard grease with high viscosity and no fluidity, that is, grease with low consistency, is applied to tooth surfaces of worms and turbines. When ...
