Double speed sprocket drawings
Double-speed sprocket drawings are widely used in heavy industry, quality machinery, food production, style props, oil and other old mechanical transmissions, etc.
Build in the double-speed sprocket drawing
. The tooth profile of the double-speed sprocket drawing The tooth profile of the double-speed sprocket drawing is the only way for the guard chain to successfully undulate and mesh with investment. Carefully increase and reduce the sprint and confrontation contact stress of the chain link during meshing, and it should be easy to cause.
Generally speaking, the tooth profile of the end face of the double-speed sprocket drawing.It is composed of three arcs aa, ab, cd and three influencing bc, using three arcs-influencing tooth profile.The tooth profile is made by the standard. There is no need for the quick end tooth profile on the drawings of the double-speed sprocket. You need to bookmark the "tooth profile specially made according to the 3RGB1244-85 index" on the drawing, but it should be the axis of the double-speed sprocket drawing. For face tooth shape, please refer to the manual of implicated establishment for its size.
. In the double-speed sprocket drawing
Small-diameter double-speed sprocket drawings are generally integrated, and ordinary-diameter double-speed sprocket drawings are mostly spoke-type. In order to facilitate handling, installation and reduction, the effect on the spokes, large-diameter double-speed sprocket drawings can be combined At this time, the gear ring and the wheel core should be made of suitable application, suitable application, suitable application, suitable application, and application can be specially made of different materials!
. Double-speed sprocket drawing materials
The drawing materials of the double-speed sprocket should protect the teeth of some people and damage. Therefore, the tooth surface of the double-speed sprocket drawing is generally positioned and heated so that it can be cleaned.
Double speed sprocket drawing repair circuit
, The tightness of the double-speed sprocket drawing should be applied. If it is too tight, the injection will complete and exit. If the bearing is inattentive, there will be four reducers; if the double-speed sprocket drawing is too loose, it will leap over and be environmentally friendly.The elastic width of the double-speed sprocket drawing is: from the double-speed sprocket drawing sprocket forging or pressing down, it is almost 2%-3% of the key distance of the double-speed sprocket drawing.
, The double-speed sprocket drawing should be installed on the shaft with metal and complete vertical.In the same transmission medical equipment, the end faces of the two double-speed sprocket drawings should only be in the same working plane. When the key distance of the double-speed sprocket drawing is below 0.5 meters, the pipe can be environmentally friendly; the key distance of the double-speed sprocket drawing is above .5 meters In the time, the pipe can be environmentally friendly.However, it is not allowed to use the left and right of the drawing teeth of the overlapping double-speed sprocket. If the two-wheel offset sprocket forging is inadvertently exposed, the four major reducers for environmental protection and promotion are revealed.When repairing double-speed sprocket drawings, only pay attention to patrol and analyze the offset double-speed sprocket drawings.
