Description
Technical field
The present invention relates to the cycloid hydraulic motor that a kind of hydraulic energy is changed to mechanical energy, especially with preceding cover supporting structure
A kind of cycloid hydraulic motor, belong to hydraulic transmission technology field.
Background technology
Cycloid hydraulic motor is conventional fluid pressure drive device, is a kind of low-speed big torque motor, with small volume, unit
Power density is big, efficiency high, the wide range of speeds the advantages of, be widely applied, and with industrial and agricultural development level is improved should
With will be more extensive.
The basic structure of such device be body shell or after cover and be formed with inlet and refluxing opening, one end is nibbled equipped with cycloidal-pin wheel
Secondary and flow-distribution mechanism is closed, flow-distribution mechanism can be placed on before or after cycloidal pinion engaged pair, typically preceding（Body shell side）For axle
Flat valve, rear（Bonnet side）For plane flow, the other end is equipped with output shaft.The rotor of cycloidal pinion engaged pair passes through interior flower
Key is engaged with the external gear of universal driving shaft one end, and the other end of universal driving shaft is connected with output shaft transmission.During work, flow-distribution mechanism make into
Liquid mouth engages chamber connection with the extension of cycloidal pin wheel set, and the contraction chamber of cycloidal pin wheel set is connected with refluxing opening.As a result, pressure
Liquid enters after body shell or bonnet from inlet, and chamber is engaged in the extension into cycloidal pinion engaged pair formation, makes its volume continuous
Expand, while liquid then flows back from refluxing opening in the contraction engagement chamber of cycloidal pinion engaged pair formation；In the process, cycloidal pin
The rotor of wheel Meshing Pair is expanded engagement chamber drives rotation with the pressure differential that chamber is engaged in contraction, and this rotation is passed through into universal driving shaft biography
Output shaft output is delivered to, so as to realize conversion of the hydraulic energy to mechanical energy.At the same time, flow-distribution mechanism is also driven by universal driving shaft and revolved
Turn, the continuous switching connected state gone round and begun again enables transfer process to continue.So, motor just can be continuously defeated
Go out moment of torsion, it may be said that cycloidal pinion engaged pair and flow-distribution mechanism are the cores of hydraulic motor.
According to the applicant understood, the cycloid hydraulic motor [such as axle flow] of prior art is used substantially has front-cover structure, this
The seams of Φ 82.55 of kind typical SAE A type standards, radial structure is compact, and protecgulum is pacified on protecgulum as the positioning spigot of motor
Dress rotation skeleton axle envelope, and using the connected mounting flange face of screw, this structure causes the superposition of at least 2 times of positioning spigot,
The axiality control numerical value for making seam install circle and output shaft is increased, and is unfavorable for the stress of motor, is influenceed the performance of product.Due to
The deficiencies in the prior art so that high speed flow motor（A kind of particular plane flow motor）Due to the adverse effect of front-cover structure,
Using monoblock type mounting flange, and cause rotation skeleton axle envelope fitting depth too big, inconvenience etc. is changed in maintenance.
The content of the invention

Pass through the innovation of protecgulum and its sealing structure, positional precision of the lifting with protecgulum seam motor, sealed reliability, skeleton axle
The maintenanceability of envelope, strengthens assembling and the maintenanceability of bearing, reduces processing technology of Motor Components etc..
In order to reach object above, a kind of cycloid hydraulic motor basic technical scheme of the invention is：Including with Method for Installation
The body shell in blue face, the output axle construction for the torque output being placed in body shell, and be connected with the body shell using connecting bolt
Turn that stator is secondary, runner and bonnet with streaming system and fluid turnover motor inner chamber；It is theed improvement is that：The body shell has
Install in positioning spigot, the seam of the body shell and be provided with protecgulum, the protecgulum is provided with rotary shaft sealing, and the protecgulum uses spiral shell
Nail is fixed together with body shell, and having on described protecgulum has part in part screw socket cap mounting hole, described body shell
Screw socket cap mounting hole, the socket cap mounting hole of the screw is collectively forming on protecgulum with the mounting hole in body shell.
Above technical scheme is further improved：One end of the protecgulum for protrusion step, one end of step against
Fore bearing on output shaft, the step disc carries out gap with body shell hole and coordinates one annular groove of setting in positioning, the body shell hole,
Annular groove installs O-ring seals.
Above technical scheme is further improved：The rotary shaft sealing set between the protecgulum and output shaft is skeleton
Axle envelope, the fore bearing uses cylinder roller bearing, and the cylinder roller bearing is made up of cylindrical roller and support frame, the circle
Post roller is arranged in the groove of the machining of support frame.
Compared with the gerotor motor of prior art, the positioning spigot of motor is body shell after above-mentioned improved structure of the invention
A part, precision is high, intensity is reliable, and the socket cap mounting hole of the part screw in body shell seam, which is set, cleverly solves seam
The problem of compact conformation, it is ensured that the effective thickness of seam, and the requirement on machining accuracy of protecgulum is substantially reduced, while improving production
The alternative that reliability, maintainability, assembling and its bearing of product are set.
