Jewel fixture is made up of following structure usually: isostere, be located at the worm screw in isostere, with some pin teeth of worm engaging, the lamina tecti at isostere top, the side cover plate of isostere side, the two ends of worm screw are provided with bearing, are provided with hold-down nut outside bearing.At present, adopt plane bearing to fix with in the two ends of worm screw and isostere two sides bearing block, in use there is two problems, first: plane bearing position frequently occurs oil leakage phenomenon always, can not butter well in seal oil chamber.Second: bearing wear easily causes bearing locking, cause the overall dead pin of aluminium isostere to work; 3rd, can not longitudinal direction adjustment be carried out to worm screw and accurately locate, easily occur that worm screw tilts or unbalanced phenomenon, affect the mechanics transmission effect between worm screw and pin tooth, even cause fixture pin to rotate malfunctioning; Meanwhile, also exacerbate loss between worm screw and pin tooth because of the mutual frictional force between worm screw and pin tooth, reduce its service life.
Summary of the invention
In order to solve the technical problem mentioned in background technology, the purpose of this utility model is to provide a kind of sealed jewel fixture transmission mechanism.
The technical solution adopted in the utility model is as follows:
A kind of sealed jewel fixture transmission mechanism, mainly comprise isostere, the worm screw be located in isostere, be provided with the fixture pin of pin tooth, the pin tooth of fixture pin and worm engaging, it is characterized in that: described isostere both ends of the surface are provided with bearing block successively, outerplanar sealing ring, fixing seal bearing holder (housing, cover), and the plane endoporus sealing ring be located in fixing seal bearing holder (housing, cover) and ball bearing; Described fixing seal bearing holder (housing, cover) is positioned at bearing saddle bore; Fixing seal bearing holder (housing, cover) outerplanar is provided with annular groove, and for installing outerplanar sealing ring, fixing seal bearing holder (housing, cover) endoporus plane is provided with step, for mounting plane endoporus sealing ring.
Described one sealed jewel fixture transmission mechanism, is characterized in that: described bearing is 2.
Described one sealed jewel fixture transmission mechanism, is characterized in that: described bearing block two side plane is respectively equipped with set screw hole, and set screw is provided with set screw in hole, for longitudinally regulating the position of fixing seal bearing holder (housing, cover).
Described one sealed jewel fixture transmission mechanism, is characterized in that: described worm screw one end is provided with the diplopore location worm screw head for fixing worm screw.
Fixing seal bearing holder (housing, cover) is increased in the utility model isostere both ends of the surface bearing block, fixing seal bearing holder (housing, cover) is by bearing seat surface, plane increases outerplanar sealing ring, such butter that can prevent spills from fixing seal bearing holder (housing, cover) cylindrical, increase plane endoporus sealing ring between bearing holder (housing, cover) endoporus and inner plane, this structure can prevent butter from spilling from fixing seal bearing holder (housing, cover) endoporus.Adopt two ball bearing fixed conveyor in fixing seal bearing holder (housing, cover), this structure can prevent the stuck rear out-of-work phenomenon of bearing well, and after wearing and tearing stuck phenomenon appears in a bearing, another bearing can replace work.Bearing block two ends respectively process a set screw hole, longitudinally can regulate the center of fixing seal bearing holder (housing, cover), prevent worm eccentric and fixture pin not dead.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front cross-sectional structural representation of the present utility model;
Fig. 3 is top view cross section structural representation of the present utility model;
In figure: 1-isostere; 2-worm screw; 3-fixture pin; 4-bearing block; 4-1-set bolt; 4-2-set screw hole; 4-3-set screw; 5-outerplanar sealing ring; 6-fixing seal bearing holder (housing, cover); 7-plane endoporus sealing ring; 8-ball bearing; 9-hold-down nut; 10-diplopore location worm screw head.
detailed description of the invention:
Below in conjunction with accompanying drawing 1-3, the utility model is further described in detail.
The utility model is the improvement carried out existing jewel fixture, the main portions improved is its transmission mechanism, its primary structure of existing fixture comprises isostere 1, the worm screw 2 be located in isostere 1, be provided with the fixture pin 3 of pin tooth, the pin tooth of fixture pin 3 engages with worm screw 2, isostere 1 both ends of the surface are provided with bearing block 4, are fixed in isostere 1 by set bolt 4-1.This structure makes bearing portion frequently occur oil leakage phenomenon, can not butter leakage of oil well in seal oil chamber.In order to solve this technical problem, the utility model is provided with fixing seal bearing holder (housing, cover) 6 in bearing block 4 hole, and be provided with annular groove at the outerplanar of fixing seal bearing holder (housing, cover) 6, be equipped with outerplanar sealing ring 5 in annular groove, prevent butter from spilling from fixing seal bearing holder (housing, cover) 6 cylindrical; Fixing seal bearing holder (housing, cover) 6 endoporus plane is provided with step, step is equipped with plane endoporus sealing ring 7, and this structure can prevent butter from spilling from fixing seal bearing holder (housing, cover) endoporus.
