Abstract
The worm wheel and shaft, based on the axisted technology, infuses the lubricating oil directing into the rubbing surface between the worm wheel and shaft, thus minimize the friction and waste. The new aparatus can substitute the multilevel gear and chain wheel to change the existed status of narrow application and low utilization.
Description
Type of the present invention relates to mechanical transmission, especially is the worm and gear transmission.
At present, known worm and gear transmission, lubricated or be lubricated toward friction place oil spout with oil pump by oil sump, have that worm and gear frictional force is big, rubbing surface big, wearing and tearing greatly, heat is big.Mainly be very little the moist of rubbing surface outside that only depend on of oil in the rubbing surface, do not bring into play lubricant oil due lubrication in rubbing surface.
The objective of the invention is to change its shortcomings and deficiencies provides a kind of and has 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 type of the present invention is achieved in that power drives worm and worm gear and rotates in oil sump, the oil duct that the inner oiling of pair worm and wheel rubbing surface 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, 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.
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.
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).
