Abstract
The utility model discloses a secondary enveloping ring surface worm gear, belongs to the technical field of transmission, and solves the problems that the existing worm gear is poor in lubricating effect and unreasonable in structural design. The secondary enveloping ring surface worm gear comprises a gear shaft and a disc-shaped body sleeved on the gear shaft, wherein a plurality of gear teeth evenly distributed and slantingly arranged along the axis of the body are arranged on the outer ring surface of the body, a gear groove is respectively formed between every two adjacent gear teeth, oil through holes are arranged on the gear teeth, one ends of the oil through holes are connected with the gear grooves arranged on one side of the gear teeth, and the other ends of the oil through holes are connected with the gear grooves arranged on the other side of the gear teeth. The secondary enveloping ring surface worm gear has the advantages of being reasonable in structural design, good in lubricating effect and the like.
Description
Technical field
The utility model belongs to the driving component technical field, relates to a kind of worm gear, particularly a kind of twice-enveloping anchor ring worm gear.
Background technique
Drive structure of gear worm is mainly used to transmit motion and the power between two alternating axiss, and its application area is very extensive.Along with the continuous development of science and technology and the raising day by day of the level of production, common drive structure of gear worm is because the number of teeth of participation engagement simultaneously is few, it transmits moment of torsion and is restricted, have easy wearing and tearing, shortcoming such as working life is short and volume is big, this common drive structure of gear worm can not satisfy people's usage requirement.
In order to reduce the wearing and tearing between worm gear and the worm screw in the course of the work, often can leave the gap after both engagements and enter for lubricant oil.Because the existence of backlash brings impact, vibration and noise must for modern Mechatronic Systems, also can reduce the servo-actuated precision of system and stability.If arrange backlash less, though can improve the transmission accuracy of transmission, the sliding friction aggravation of the flank of tooth on the worm gear and worm screw addendum surface, lubricant oil is difficult for it is lubricated, and causes the working life of worm and gear low.Therefore, it is very necessary needing the worm gear of a kind of reasonable in design of proposition.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the twice-enveloping anchor ring worm gear of a kind of reasonable in design, high lubricating effect.
The purpose of this utility model can realize by following technical proposal:
A kind of twice-enveloping anchor ring worm gear, comprise wheel shaft and the body that is plate-like that is set on this wheel shaft, have some gear teeth that are obliquely installed along body axis on the outer ring surface of described body, and some gear teeth evenly distribute, constitute race between the two adjacent gear teeth, it is characterized in that having oil through on the described gear teeth, the race of this gear teeth one side of one end of described oil through is communicated with, and the other end of described oil through is communicated with the race of this gear teeth opposite side.
In above-mentioned twice-enveloping anchor ring worm gear, have the arc-shaped slot that inwardly concaves on the outer ring surface of described body, the above-mentioned gear teeth are arranged in arc-shaped slot.
In above-mentioned twice-enveloping anchor ring worm gear, has the arc port that inwardly concaves on the outer side surface of the described gear teeth.
Compared with prior art, this twice-enveloping anchor ring worm gear has the following advantages:
The outer ring surface of body is arc-shaped slot, and the outer side surface of the gear teeth is arc port, its reasonable in design, abundant and worm meshing; Offer oil through at the gear teeth, worm gear is in rotating process, and lubricant oil is squeezed and can enters in the race of gear opposite side in the race of the gear teeth one side, effectively the gear teeth is lubricated, and has reduced wearing and tearing, has prolonged the working life of worm gear.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Among the figure, 1, wheel shaft; 2, body; 3, the gear teeth; 31, arc port; 4, race; 5, oil through.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Twice-enveloping anchor ring worm gear as shown in Figure 1, comprise wheel shaft 1 and the body that is plate-like 2 that is set on this wheel shaft 1, have some gear teeth 3 that are obliquely installed along body 2 axis on the outer ring surface of body 2, and some gear teeth 3 distribute evenly, constitute race 4 between the two adjacent gear teeth 3.
In order to increase lubrication effect, as shown in Figure 1, have oil through 5 at the gear teeth 3, the race 4 of these gear teeth 3 one sides of an end of oil through 5 is communicated with, and the other end of oil through 5 is communicated with the race 4 of these gear teeth 3 opposite sides.
As shown in Figure 1, have the arc-shaped slot that inwardly concaves on the outer ring surface of body 2, the gear teeth 3 are arranged in arc-shaped slot; Has the arc port 31 that inwardly concaves on the outer side surface of the gear teeth 3.
The reasonable in design of this twice-enveloping anchor ring worm gear, abundant and the worm meshing of energy, the number of teeth that contacts simultaneously during engagement is more, offer oil through 5 at the gear teeth 3, worm gear is in rotating process, and lubricant oil is squeezed and can enters in the race 4 of gear opposite side in the race 4 of the gear teeth 3 one sides, effectively the gear teeth 3 is lubricated, reduce wearing and tearing, prolonged the working life of worm gear.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as wheel shaft 1, body 2, the gear teeth 3, arc port 31, race 4, oil through 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
