Abstract
The utility model discloses a gear-shifting transmission gear of a power transmission device, comprising a gear main body. A plurality of outer teeth are arranged at the outer side of the gear main body, and a center hole is arranged in the center of the gear main body. The gear-shifting transmission gear is characterized in that a plurality of oil tanks are arranged on one or two surfaces of the gear main body and the opening end of each oil tank is communicated with the center hole. As the plurality of centripetal oil tanks are arranged on the surface of the gear, more lubricating oil can be carried in rotation to flow into a transmission shaft and a bearing through the oil tanks; therefore, the lubricating oil at the positions of the transmission shaft and the bearing can be greatly increased, and the lubricating effect of such components as the transmission shaft, the bearing and the like can be obviously improved; moreover, the gear is convenient and rapid to machine, so that the machining efficiency can be greatly increased, the machining cost can be reduced and the requirements of medium/small-sized machining enterprises can be met.
Description
Technical field
The utility model relates to a kind of driving gear of actuating unit, especially the gear shift driving gear of actuating unit.
Background technique
In machine power is transmitted, speed reducer as automobile, motorcycle, farm machinery, motor etc., in speed reducer generally driving shaft (input shaft), countershaft, all be provided with above the output shaft many groups can match the engagement driving gear pairs, reach the rotational velocity of change axle to obtain the purpose of multiple transmission speed by the pitch wheel pair, export to obtain different moments of torsion by the rotational velocity that changes axle simultaneously, satisfy the needs of different gear transmissions.The driving gear of prior art is owing in high speed rotating, just need good lubricating, otherwise just broken easily, or at high temperature produced bigger wearing and tearing, reduced working life, or at high temperature produce very big thermal distortion, cause killing between the pitch wheel pair and can't transfer motion power etc.; In the driving gear that generally adopts splash lubrication, roll oil lubrication self and lubricated transmission shaft (input shaft in the transmission case during driving gear rotation, countershaft, output shaft etc.) and the bearing on the transmission shaft, but the lubricant oil of rolling during the rotation of the driving gear of prior art is few, substantially can satisfy lubricating to gear self, but the lubricant oil of the bearing on inflow transmission shaft and the transmission shaft seldom, cause the lubrication effect of the parts such as bearing on transmission shaft and the transmission shaft relatively poor, the heat that transmission shaft and bearing produce when high speed rotating can not in time dispel the heat by lubricant oil, certainly will increase its thermal expansion amount, quicken its wearing and tearing, reduce its working life etc., can not satisfy the needs of transmission.
Summary of the invention
The lubricant oil of rolling when the utility model rotates at prior art gear shift driving gear is few, the lubricant oil of the bearing on inflow transmission shaft and the transmission shaft seldom, cause the lubrication effect of parts such as transmission shaft and bearing relatively poor, its heat that produces when high speed rotating can not in time dispel the heat by lubricant oil, increase its thermal expansion amount, quicken its wearing and tearing, reduce deficiencies such as its working life, provide a kind of lubricant oil of rolling when rotated more, the lubricant oil that flows into transmission shaft and bearing significantly increases, the lubrication effect of parts such as transmission shaft and bearing is the gear shift driving gear of actuating unit preferably.
The technical solution of the utility model: the gear shift driving gear of actuating unit, comprise the gear body, be manufactured with some external tooths in the outside of gear body, the center of gear body is a center hole; It is characterized in that: one or two surface at the gear body, several oil grooves are set, the opening end of each oil groove all is communicated with center hole.
Further feature is: each oil groove all is arranged on the tangent direction of center hole, and is vertical with the outer side wall of center hole.
Described oil groove is four, equidistant each other even layout, and the angle of the axis of each oil groove and center hole all is 45 degree.
The gear shift driving gear of the utility model actuating unit with respect to prior art, has following characteristics:
1, at gear surface several oil grooves entad is set, the lubricant oil of rolling when rotated is more, lubricant oil flows into transmission shaft and bearing by oil groove, increases considerably the lubricant oil at transmission shaft and bearing place, and the lubrication effect of parts such as transmission shaft and bearing significantly strengthens.
2, Gear Processing is convenient, fast, can increase substantially work efficiency, reduces the time cost of processing,
Satisfy the needs of middle-size and small-size machining enterprise.
Description of drawings
Fig. 1 is the utility model driving gear structure sectional view;
Fig. 2 is the left view (part) of Fig. 1.
Embodiment
In figure, the gear shift driving gear of the utility model actuating unit comprises gear body 1, is manufactured with some external tooths 2 in the outside of gear body 1 according to designing requirement, and the center of gear body 1 is a center hole 3; Improvement of the present utility model is one or two surface at gear body 1, and several oil grooves 4 are set, and the opening end of each oil groove 4 all is communicated with (outer side wall of center hole 3 is communicated with) with center hole 3; Optimum design is the tangent direction that each oil groove 4 all is arranged on center hole 3, and is vertical with the outer side wall of center hole 3; Described oil groove 4 is four, equidistant each other even layout, and each oil groove 4 all is 45 degree with the angle of the axis of center hole 3.Described oil groove 4 can be three of equidistant even layout, and the angle between adjacent two each and every one oil grooves 4 is 120 degree.The degree of depth and the width of oil groove 4 design according to technological requirement, and the degree of depth and width are generally all at several millimeters.
Be arranged on the rotatingshaft at driving gear of the present utility model, during the driving gear rotation, it is in the floodlubrication oil that oil groove 4 wherein turns to low level, be full of lubricant oil in the oil groove 4 wherein, the lubricant oil of rolling during rotation is more, and the oil groove 4 of the lubricant oil of rolling when rotated by entad flows into center holes 3, promptly flows to parts such as the rotatingshaft that cooperates with center hole 3, bearing, increase considerably the lubricant oil at transmission shaft and bearing place, the lubrication effect of parts such as transmission shaft and bearing significantly strengthens.
