Description
Technical field
The present invention relates to the transmission device field, it is the composite set of a kind of plane table thermoconductivity meter and cycloid hydraulic motor, also claim a kind of cycloid hydraulic motor with plane table thermoconductivity meter, or be called the plane table thermoconductivity meter that a kind of cycloid hydraulic motor drives again, with hydraulic pressure can be power, the driving mechanism revolution is widely used in all kinds of mechanical fields such as civil works, building, mining and metallurgy, machining.
Background technique
In recent years, the oil hydraulic motor MANUFACTURER comprises the combination with or without break with oil hydraulic motor and plane table thermoconductivity meter, makes whole pattern and offers the user.Because compact structure, easy for installationly be widely used in fields such as engineering machinery.Chinese patent 01226292.7, name is called " fluid motor-driven driving speed reducer " (as shown in Figure 4), be a kind of two-stage epicyclic reduction and band brake of adapted axial-piston hydraulic motor, hydraulic motor output shaft 10 links by double as joint sleeve 15 and one-level sun gear 12, realizes that oil hydraulic motor connects with the unsteady of chopped-off head planetary mechanism.03142082.6 name is called " Hydraulic Motor and Integrated Reducer Driving Device " (see figure 5), discloses the structure of a kind of and aforementioned similar not band brake, employing radial piston hydraulic motor and the integrated pattern of two-stage epicyclic reduction.Chopped-off head sun gear 13 connects with the internal spline of hydraulic motor output shaft 3.Above-mentioned prior art adapted axial-piston hydraulic motor or radial piston hydraulic motor, and all be by a certain coupling retarder to be passed in rotation from the output shaft of motor, the sequence number of Fig. 4 and Fig. 5 are the prior art original detail number, down with.
Cycloid hydraulic motor is that a kind of application is very extensive, the oil hydraulic motor of function admirable.That the advantage of cycloid hydraulic motor embodies a concentrated expression of is simple in structure, volume is little, the torque of light weight, equal quality is big, and unit mass power is big more than the oil hydraulic motor of other types.And speed range is wide, it is reliable to use, low-speed stability is good, cheap.Whole world Annual output is above 1,000,000, be widely used in (Zhao Yingyue: oil hydraulic motor in the equipment such as all types of plastic machinery, engineering machinery, farm machinery, coal mine machinery, handling machinery, fishery machinery and special purpose machine tool, publishing house of Shanghai Communications University February in 2000 the 1st edition, P100).But the specification of cycloid hydraulic motor can not be done very greatly.Therefore, output torque be restricted (≤2500Nm); Its axial dimension is bigger, joins that axially size can be bigger behind retarder and the break again, will influence its supporting application limit.
As the right of Fig. 3, with depicted as solid lines is the structural representation that a kind of end face is joined the cycloid hydraulic motor of oil.It forms (distinguishing with the dot and dash line square frame) by two-part: F part---part that mainly comprises output shaft, bearing, front case: M part---mainly comprise motor stator, rotor, join the part of oil and rear case.Have and a kind ofly have protecgulum but do not have the cycloid hydraulic motor of bearing support, its output is the long shaft coupling that spline is processed at two ends, but when connecting with retarder, prior art needs one to be processed with internal spline, and has the external splines on the sun gear of external splines that the joint sleeve of supporting centering will long shaft coupling one end and retarder to link.
The gear reducer MANUFACTURER provides the gear reducer of direct adapted commodity cycloid hydraulic motor and equipment manufacturers to adopt the commodity cycloid hydraulic motor on retarder, with a kind of form of importing joint sleeve the output shaft of motor and the sun gear of retarder is linked.The part of drawing with double dot dash line as the left side of Fig. 3 represented plane table thermoconductivity meter and with the existing joining method of cycloid hydraulic motor (part of representing with solid line).Joint sleeve 8., Fig. 3 has the part that the interior sequence number of circle is prior art, be processed with internal spline, the sun gear of plane table thermoconductivity meter right-hand member 9. is processed into crowned spline, joint sleeve 8. internal spline and the output shaft of cycloid hydraulic motor 1. external splines and sun gear 9. the right-hand member crowned spline link.Reflected similar joining method as Fig. 4; The internal spline that the other end of the sun gear 13 of Fig. 5 makes external splines and motor output shaft 3 links.
Above-mentioned described Placement and complex structure, it is big especially can't to take volume into account when the adapted cycloid hydraulic motor, particularly the too big disadvantage of axial dimension.
If cycloid hydraulic motor and plane table thermoconductivity meter can be made up, and can simplify their joining method, make axial dimension little, provide with integral form, the advantage of performance cycloid hydraulic motor increases the output torque through the plane table thermoconductivity meter deceleration, will have good market prospects.
Summary of the invention
