Abstract
The utility model belongs to the technical field of rotary driving device parts, and particularly relates to an internal gear ring of a hydraulic rotary driving device. The technical problems that the design is not reasonable, the structure is complex, and cost is high in the prior art are solved. The internal gear ring of the hydraulic rotary driving device comprises an annular body which is provided with a plurality of nail passing holes which are evenly distributed in the circumference of the annular body, the inner wall of the annular body is provided with a plurality of gear teeth which are evenly distributed on the circumference of the inner wall of the annular body, an annular positioning step which is placed at one end of the annular body is arranged inside the annular body, a first annular groove and a second annular groove are formed in the side portion of the annular body, and the groove bottom diameter of the first annular groove is equal to the groove bottom diameter of the second annular groove. Compared with the prior art, the internal gear ring of the hydraulic rotary driving device has the advantages of being simple in structure, easy to manufacture, low in cost, moreover, convenient to mount, firm in fixing, stable in driving, and long in service life.
Description
Technical field
The utility model belongs to revolution driver accessory technical field, especially relates to a kind of ring gear of hydraulic gyration transmission device.
Background technique
The hydraulic gyration driver generally is by oil hydraulic motor, break, and speed reducer, the valve group, the gear end structure forms, and is transferred to gear-box by oil hydraulic motor and plays the increase moment of torsion, and the effect that underspeeds realizes the requirement of low-speed big.There is complex structure in the ring gear of existing hydraulic gyration transmission device and be difficult for installs, locate inaccurate, the technical problem such as working life is short.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of speed reducer debarkation rotary transmission device [application number: CN201120378453.X], comprises the valve piece, motor and one-level planetary part, the secondary planet parts, bearing support and gear shaft, described valve piece connecting motor, the motor output end outside connects brake member, motor output end right side head portion connects the one-level planet wheel, the one-level planet wheel connects primary planet carrier one end, and primary planet carrier is connected with the secondary planet wheel, and the secondary planet wheel connects the secondary planet frame; Gear shaft is installed in the bearing support, and the gear shaft left end outside is fixed with the secondary planet frame.
Although such scheme has solved the problem that prior art exists to a certain extent, still exist complex structure and be difficult for installing, locate the technical problems such as inaccurate and working life is short.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, the ring gear of the hydraulic gyration transmission device that structure is simpler and easy for installation.
For achieving the above object, the utility model has adopted following technical proposal: the ring gear of this hydraulic gyration transmission device comprises annular solid, be provided with the excessively nail hole that some even circumferentials distribute at annular solid, be provided with the teeth that some even circumferentials distribute at the annular solid inwall, it is characterized in that, be provided with the circular orientation step that is positioned at the one end in the described annular solid, be provided with the first circular groove and the second circular groove at the annular solid sidepiece, described the first circular groove bottom land footpath directly equates with the bottom land of the second circular groove.Obviously, the utlity model has simple in structure, be easy to make and low cost of manufacture, and easy for installation, fixed and transmission stable, long service life meets the development trend of current social technology.
In the ring gear of above-mentioned hydraulic gyration transmission device, be respectively equipped with chamfer surface at the two ends of each teeth.The convenient installation.
In the ring gear of above-mentioned hydraulic gyration transmission device, described excessively nail hole number is 20.
Compared with prior art, the advantage of the ring gear of this hydraulic gyration transmission device is: simple in structure, be easy to make and low cost of manufacture, and also easy for installation, fixed and transmission stable, long service life meets the development trend of current social technology.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, annular solid 1, mistake nail hole 11, teeth 12, chamfer surface 12a, circular orientation step 13, the first circular groove 14, the second circular groove 15.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the ring gear of this hydraulic gyration transmission device comprises annular solid 1, be provided with the excessively nail hole 11 that some even circumferentials distribute at annular solid 1, optimized project, excessively nail hole 11 quantity here are 20, be provided with the teeth 12 that some even circumferentials distribute at annular solid 1 inwall, in annular solid 1, be provided with the circular orientation step 13 that is positioned at the one end, be provided with the first circular groove 14 and the second circular groove 15 at annular solid 1 sidepiece, described the first circular groove 14 bottom lands footpath directly equates with the bottom land of the second circular groove 15.Obviously, the present embodiment is simple in structure, be easy to make and low cost of manufacture, and easy for installation, fixed and transmission stable, long service life meets the development trend of current social technology.
Specifically, be respectively equipped with chamfer surface 12a at the two ends of each teeth 12 of the present embodiment.The convenient installation.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.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 more used annular solid 1, crossed the terms such as nail hole 11, teeth 12, chamfer surface 12a, circular orientation step 13, the first circular groove 14, the second circular groove 15, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
