Abstract
A mechanical transmission vacuum lubrication device comprise a circulating oil channel under the function of vacuum and a friction surface of a lubricated object, which is characterized in that circulating oil are supplied at the center hole of a centrifugal force rotating object and the position of friction by a vacuum lubrication circulating oil channel. The mechanical transmission vacuum lubrication device exceeds the efficiency of mutual splash lubricating of conventional gears and is widely suitable for the mechanical field.
Description
Affiliated technical field
The utility model relates to mechanical transmission, gear, axle etc., especially is the worm and gear transmission.
Background technique
At present, known worm and gear transmission, gear, axle etc., lubricated or by oil sump with the past friction place oil spout of oil pump, be lubricated.Have that worm gear transmission ratio brings greatly that friction is big, attrition surface is big, the oil in the attrition surface is very little only depends on moistening of attrition surface outside, therefore produce the shortcomings and deficiencies that heat is big, abrasion is big, greatly limit application area, it mainly is the lubricated not due lubrication in attrition surface of not performance, it is big directly to have influenced worm gear transmission ratio, moment of torsion is big, compact structure, the extensive and long-term application of the efficient powerful gearing performance of the little grade of noise.
Summary of the invention
The purpose of this utility model is to change its shortcomings and deficiencies to provide a kind of and have that wearing and tearing are little, heat is little, lubricant oil is injected into worm gear and worm screw attrition surface internal lubrication.Efficient worm and gear driving gear, axle etc., the mechanical transmission lubrication of technology extensive use, innovation scheme.
The purpose of this utility model is achieved in that the transmission in fuel tank of a kind of mechanical transmission vacuum lubricating device, it is characterized in that: make lubricant oil be transported to oil outlet by the power of self rotating, with its composition transmission attrition surface internal lubrication through the oil duct of filler opening.Power drives object and rotates in oil sump, oil duct as worm gear and the inner oiling of worm screw attrition surface, object has the through hole oil duct of inlet/outlet, the attrition surface of the back outlet in hole, and the preceding import in hole is that filler opening is at non-attrition surface, non-attrition surface does not mesh the face of friction with tooth, for example: wheel (rim) wide face, the size in hole and quantity can be decided according to the actual requirements, and worm screw is rotated in oil sump, produce centrifugal force and form vacuum in the middle of tooth and tooth, the oil in the oil duct through hole constantly flows.Supply attrition surface internal lubrication, have the original rotation, self form oil well pump.The oil outlet place has screw thread to stop fuel-displaced refluence and the storage effect is arranged, and oil outlet is an ellipse, and the oil outlet below has the trigonometric form sulculus to be beneficial to oil extraction.Oil in the oil duct injects attrition surface inside, is admitted by the oil groove on the worm gear flank of tooth, and oil can constantly be stored and overflow, and the big smallest number of oil groove is decided as required.On the one circle tooth a plurality of oil ducts can be arranged.
Owing to adopt such scheme, object rotates and produces the centrifugal force oil extraction to lubricating unfavorable factor: become favorable factor and improve revolution, heavy duty and life-span.The unprecedented worm and gear of giving full play to powerfully best embodies the structural advantage of mechanical lever transmission principle, enters various industries of mechanical field and department effectively significantly, replace multi-stage gear, sprocket wheel etc. and can obtain big driving torque, energy-conservation, change the low speed rotation of worm and gear, the intermittent present situation of rotating and being difficult for heavy duty, be the important breakthrough in the mechanical field, have far reaching significance.Purposes will be popularized more extensively and profoundly.Effectively promote the development of mechanical transmission fields.
Description of drawings
Further specify below in conjunction with drawings and Examples.
Fig. 1 is that worm and gear is in conjunction with figure.
Among the figure: 1 worm screw, the 2nd, worm screw oil duct filler opening, the 3rd, worm tooth attrition surface lubricating oil duct oil outlet, the 4th, elongated oil groove on the worm-gear tooth attrition surface, the 5th, the wide face of worm tooth rim, the 6th, worm screw is rotated the region of no pressure that produces.
Embodiment
Power makes worm screw rotate region of no pressure (6) the rotary worm lubricating oil duct filler opening (2) that produces through worm screw (1) among Fig. 1 and pours into lubricant oil, through oil channel, make oil inject elongated oil groove (4) on the attrition surface inside of worm gear and worm screw and the worm-gear tooth attrition surface in worm tooth attrition surface lubricating oil duct outlet (3).
