Abstract
The utility model relates to the mechanical transmission of a worm gear and a worm rod, which comprises a lubrication oil passage arranged in the transmission friction surface of the worm gear and the worm rod, wherein the lubrication oil is directly filled in and lubricates the friction surface of the worm gear and the worm rod through the lubrication oil passage. The utility model changes the large defects of large friction, large loss and large heat for the worm gear and the worm rod.
Description
Affiliated technical field
Model utility relates to mechanical transmission, especially is the worm and gear transmission.
Background technique
At present, known worm and gear transmission, lubricated or with the past friction place oil spout of oil pump by oil sump is lubricated.Have that worm gear transmission ratio brings greatly that frictional force is big, rubbing surface is big, the oil in the rubbing surface is very little only depends on being stained with of face of gear outside to soak, therefore produce the shortcomings and deficiencies that heat is big, abrasion is big, greatly limit application area, major defect is not bring into play lubricant oil due lubrication in rubbing surface, 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 abrasion is little, heat is little, lubricant oil is injected into worm gear and worm screw rubbing surface internal lubrication.The mechanical transmission innovation scheme of efficient worm and gear drive technology extensive use.
The purpose of model utility is achieved in that power drives worm and worm gear, rotates in oil sump, and the oil duct that acts on worm gear and worm drive rubbing surface internal lubrication oil is arranged.The two sides of worm tooth has oil duct to advance, the through hole oil duct of outlet, the back outlet in hole is at rubbing surface, the preceding import in hole is at non-rubbing surface, the size in hole and quantity can be decided according to the actual requirements, worm screw is rotated in oil sump, produce potential energy, oil on the worm tooth in the oil duct through hole constantly flows, when revolving in the contact of worm and wheel rubbing surface, worm tooth non-rubbing surface oil duct via openings upwards pours into lubricant oil worm tooth rubbing surface oil duct through hole oil outlet following, and the oil outlet place has screw thread to stop fuel-displaced refluence and the storage effect is arranged, 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 rubbing 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, the technical program also adapts to the counter-rotating of worm and worm gear.
Owing to adopt such scheme, 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, changing the low speed rotation of worm and gear, the intermittent present situation of rotating and being difficult for heavy duty, is the important breakthrough in the mechanical field.
Description of drawings
Further specify below in conjunction with drawings and Examples.
Fig. 1 is that worm and gear is in conjunction with figure.
Fig. 2 is the local figure of worm screw.
Fig. 3 is the worm tooth part sectioned view.
Among the figure: 1 coupling head, the 2nd, worm tooth non-rubbing surface lubricating oil duct filler opening, the 3rd, worm tooth rubbing surface lubricating oil duct oil outlet, the 4th, elongated oil groove on the worm-gear tooth rubbing surface, the 5th, the wide face of worm tooth rim, the 6th, worm tooth lubricating oil duct generalized section.
Embodiment
Power rotates worm screw through coupling head (1) among Fig. 1, worm tooth non-rubbing surface lubricating oil duct filler opening shown in Figure 2 (2) pours into lubricant oil in the rotation, through oil duct shown in Figure 3 (6), make oil inject elongated oil groove (4) on the rubbing surface inside of worm gear and worm screw and the worm-gear tooth rubbing surface in worm tooth rubbing surface lubricating oil duct outlet (3).
Claims (4)
1, a kind of worm and gear, transmission in oil sump is characterized in that: the oil duct that lubricant oil is arranged in worm gear and worm drive rubbing surface inside.
2, according to the described worm and gear of claim 1, it is characterized in that: there is through hole oil duct opening on the two sides of worm tooth.
3, according to the described worm and gear of claim 1, it is characterized in that: worm gear and worm screw friction have the elongate slot oil duct on the worm gear face.
4, according to the described worm and gear of claim 1, it is characterized in that: wide face of worm screw wheel rim and worm gear rubbing surface have the through hole oil duct.
