Abstract
The utility model relates to a planetary speed reducer for a hydraulic gearing device, which is composed of a shell with an inner ring gear, a central gear, a planetary gear, a transmission small shaft, a pin roller, a planetary carrier, a bearing frame, etc. The utility model is characterized in that the planetary gear is supported in a planetary carrier through the transmission small shaft with a hardness surface and the pin roller, and both ends of the planetary carrier in an integral casting structure are respectively supported in the shell and a bearing seat which is fixed to the shell through a bearing. The speed reducer has the advantages of reasonable and compact structure, simple making process of the planetary carrier, improved stress situation and enhanced reliability of the mechanism, and is favorable for reducing the manufacturing cost and increasing the carrying capacity of an output shaft.
Description
The utility model relates to the power take-off mechanism of hydraulic transmission---planetary reducer.
The planetary reducer of hydraulic transmission is a power take-off mechanism, can drive operation mechanism's running of various machineries.Existing like product exists complex structure, bearing capacity smaller defect, and at first, its planetary pinion is bearing in the planet carrier by bearing, under same size condition, make bearing capacity less, and the structure transmission size is bigger, causes big, the Heavy Weight of volume, makes the corresponding raising of manufacture cost; In addition, existing planet carrier is a steel product, the branch body structure that couples together with screw by the front and back two halves, and be bearing on the monolateral bearing, not only make the manufacturing process complexity, influence output shaft simultaneously to ability to bear axial, radial force.
The purpose of this utility model is to overcome the defective of prior art and a kind of technology, designs simplification are provided, can improve the planetary reducer of hydraulic transmission of the bearing capacity of output shaft.
According to above-mentioned purpose, the technical solution of the utility model is: the planetary reducer of hydraulic transmission, comprise central gear by the hydraulic transmission rotary driving, mesh with the housing ring gear simultaneously with the planetary pinion of the circumference uniform distribution of central gear engagement, planetary pinion is bearing in the planet carrier, and drive the planet carrier output that is used as power, it is characterized in that described planetary pinion by little of the transmission with hardness surface and roller bearing in planet carrier.
Described planet carrier is a monolithic construction, two ends respectively by bearing be bearing in housing and with the fixing bearing support of housing in.
The utility model replaces the bearing of conventional construction as the supporting between planetary pinion and the planet carrier with little axle of the transmission with hardness surface and roller, adopt planet carrier, the two ends of monolithic construction to support the planet carrier that replaces branch body structure, monolateral supporting with bearing simultaneously, thereby make this compact structure reasonable, simplified the preparation process of planet carrier, manufacture cost is minimized, and has improved the bearing capacity of output shaft greatly.
Accompanying drawing 1 has provided structural representation of the present utility model.
To be elaborated again in conjunction with above-mentioned accompanying drawing to concrete structure of the present utility model below.
Referring to Fig. 1, the planetary reducer of hydraulic transmission has a central gear by the hydraulic transmission rotary driving (10), mesh with housing (6) ring gear again when being distributed on 3-4 planetary pinion (9) and the central gear engagement on the central gear circumference, therefore planetary pinion is done the rotation except that the transmission of acceptor center gear meshing, also because of revolving round the sun with the engagement of housing ring gear, because planetary pinion is to be bearing in the planet carrier (8) by little axle of the transmission with hardness surface (3) and roller (4), and the little axle of transmission is fixed by positioning screwn (5) and planet carrier, so planetary pinion drives the little axle of transmission and then drives the planet carrier rotation when revolution, output power, positioning screwn limits the little axle of transmission simultaneously and rotates and move axially.The little axle of transmission reaches Rc60-63 with the hardness of roller.
Planet carrier (8) is a monolithic construction, with QT600 spheroidal graphite cast iron integral casting forming, its two ends respectively with bearing (2) and (7) be bearing in housing (6) and with the fixing bearing support (1) of housing in, to improve the monolateral force-bearing situation of planet carrier, improve the bearing capacity of planet carrier output shaft, and roller (11) is set between central gear and planet carrier, this roller interferes with each other in the time of can avoiding central gear, each spinning of planet carrier with the central gear plane contact, contact with the planet carrier circumferential surface.
The structure of planet carrier (8) output shaft has multiple pattern, can be flange plate type structure or male splined shaft structure or female splined shaft structure or flat key axle construction, drives various work mechanism runnings by output shaft.
Claims (6)
1. the planetary reducer of a hydraulic transmission, comprise central gear (10) by the hydraulic transmission rotary driving, mesh with housing (6) ring gear simultaneously with the planetary pinion (9) of the circumference uniform distribution of central gear engagement, planetary pinion is bearing in the planet carrier (8), and drive the planet carrier output that is used as power, it is characterized in that described planetary pinion is bearing in the planet carrier by transmission with hardness surface little (3) and roller (4).
2. the planetary reducer of hydraulic transmission as claimed in claim 1 is characterized in that described planet carrier (8) is monolithic construction, two ends be bearing in housing (6) by bearing (2) and (7) respectively and the bearing support (1) fixed with housing in.
