Problems solved by technology

Its shortcoming is: because the helical gear itself does not have lubricating parts, the helical gear set in the air works for a long time and is easily damaged by high temperature and fatigue, thereby affecting the normal operation of the entire machine

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiment:

[0030] Such as Figure 1-2 As mentioned above, it is a helical gear, which includes a columnar base 1. The center of the base 1 is provided with a through groove 101 along the axis direction of the base 1. The through groove 101 is used to pass through the shaft. There are several key grooves 104 along the axial direction, and the key grooves 104 are arranged radially along the outer circumference of the inner wall of the through groove 101. The outer surface of the base body 1 is provided with helical teeth 2, and the helix angle of the teeth 2 is 25.1°~30.1° °, a groove 102 for storing lubricant is provided on the base 1 that runs through the inner wall of the groove 101, and a pinhole channel 103 connected with the groove 102 is opened at the root of each tooth 2 of the tooth 2, and the groove 102 is provided with multiple Each pinhole channel 103 corresponds to the groo...

Abstract

The invention relates to a spiral gear. The spiral gear comprises a columnar base body, wherein a penetrating groove in the axial direction of the base body is formed in the center of the base body and allows a shaft to be inserted therein in a penetrating manner; spiral teeth are formed in the outer side surface of the base body; grooves for storing a lubricant are formed in the base body and in the inner wall of the penetrating groove; and pin hole channels communicated with the grooves are formed in tooth roots of the teeth. As the pin hole channels are matched with the grooves in which the lubricant is stored, the pin hole channels can effectively lubricate the meshing face of the gear in the working state, accordingly, the temperature of the meshing face is reduced, and the fatigue strength reaching time of the meshing face is delayed.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a helical gear and a preparation method thereof. Background technique [0002] The existing Chinese patent database discloses a patent named as a helical gear of a wide-angle fabric fabricating unit. The patent application number is: 201010597502.9, the application date is: 2010.12.21, the application publication number is: CN102537278A, and the application publication date is: 2012.07.04, the device includes a gear rod and a sleeve integrally formed on the gear rod. The outer surface of the gear rod has helical teeth. The sleeve is cylindrical, and the helix angle of the teeth is 20°~25°. Its shortcoming is: because this helical gear itself does not have lubricating part, this helical gear that is arranged in the air works for a long time, is easy to be damaged by high temperature and fatigue, thereby affects the normal operation of the whole machine.
