Description
Technical field
The utility model is related to cycloid speed reducer motor interconnection technique field, specifically a kind of New-type cycloidal speed reducer
Motor connecting structure.
Background technology
In cycloid drive, conventional cycloid speed reducer is generally attached by motor connecting flange with motor,
We term it speed ends.Under normal circumstances, speed end can reach very high rotating speed when speed reducer is run（Generally have
More than 1500r/min）, this just proposition such as the mismatch error to speed reducer speed end and motor shaft and high speed end bearing assembly precision
Very high requirement, still, often due to the factors such as the limitation of machining accuracy, structure, rigging error, manufacture cost, can cause to match
Conjunction error is excessive or can not select suitable bearing, and the parts in connecting flange is caused to be damaged in speed reducer operational process
It is bad, in order to strengthen the service life of high speed end bearing, generally there is following several method：1st, improve processing technology, use high-precision
The parts such as machine tooling connecting flange and connecting shaft, 2, the higher cylinder roller bearing of use intensity, 3, change in connecting flange
Portion's structure using the bearing of bigger specification, all exists centainly by three of the above method to improve the service condition of speed end
Defect：Although the service life of speed end can be improved to a certain extent by the 1, improving machining accuracy, great number is needed to purchase
High-precision machining tool and the time for extending processing and assembling, greatly enhance the manufacturing of speed reducer into
This, although the higher roller bearing of 2, use intensity can improve the service life of bearing, roller bearing is suitable for rotating speed
Than being run under relatively low occasion, also it is easily damaged very much in the case of high-speed cruising, and the roller bearing of identical size is general
In the case of price be two to three times of deep groove ball bearing, equally increase to a certain extent speed reducer production and manufacture into
This, if 3, change connecting flange internal structure, is the service life that can improve bearing using the bearing of bigger, but uncomfortable
For all general speed reducers, the size of most bearings has structure limitation, can not increase, limitation is bigger.
Invention content
The utility model provides a kind of service life length, high transmission accuracy, speed reducer operation to solve the above-mentioned problems
More stable New-type cycloidal motor for speed reducer connection structure in the process.
The utility model is achieved through the following technical solutions in order to achieve the above object：
The utility model is a kind of New-type cycloidal motor for speed reducer connection structure, it is characterised in that：Including motor connection method
Orchid, circlip for hole, high speed end bearing, circlip for shaft, oil sealing and motor connection axle, are set on motor connecting flange
There is bearing mounting hole, high speed end bearing is mounted on motor connection axle in bearing mounting hole, is provided in bearing mounting hole solid
Determine the hole back-up ring mounting groove of circlip for hole, motor connection axle rear end is mounted in high speed end bearing, in high speed end bearing
Motor connection axle back-up ring mounting groove is provided in the motor connection axle of front end, circlip for shaft is fixed on motor connection axle baffle ring
It is fitted closely in mounting groove and with high speed end bearing, oil sealing is mounted on the motor connecting flange of high speed end bearing front end.
Further improvement of the utility model is：Oil sealing is mounted on the seal mounting hole on motor connecting flange, oil sealing
It is fixed in seal mounting hole.
Further improvement of the utility model is：It is provided in motor connection axle rear end and high speed end bearing is positioned
Positioning flange collar.
The beneficial effects of the utility model are：The characteristics of the utility model is maximum compared to conventional motor connecting flange is
High speed end bearing is mounted under the limitation of original motor connecting flange structure closest to one end of motor, the advantage of this design feature
It is to increase the span of the bearing of high speed end bearing and motor connection axle top as far as possible, makes conventional motor under same model
Connecting flange is 68mm, and the motor connecting flange of the utility model is 106mm, can be with according to the operation logic of cycloid speed reducer
Calculate the load that high speed end bearing is born mostly come from front speed reducer inside formed radial load, bearings at both ends away from
After the length of side, the radial load that high speed end bearing is born can be calculated and substantially reduced, make conventional electricity under same model
Machine connecting flange is 3475N, and the utility model motor connecting flange is 2229N；In the situation that the high speed end bearing used is constant
Under, the service life of the utility model motor connecting flange high speed end bearing will be apparently higher than height in conventional motor connecting flange
The service life of fast end bearing, conventional motor connecting flange is 8043h under same model, and the utility model motor connecting flange is
30466h, motor connecting flange reduce bearing to the distance of motor while motor connection axle both ends span is increased, subtract
Small mismatch error between motor connection axle and motor shaft improves transmission accuracy, make it is more steady in speed reducer operational process,
The high speed end bearing for comparing conventional motor connecting flange is driven parts closer to cores such as the capacity eccentric bearings of cycloid speed reducer, newly
Type connecting flange increases the distance of the two, in the case of the generation amount of heat that both runs at high speed, novel connecting flange
The heat dissipation of the heat-dissipating space of bigger, more conducively speed reducer is utilized, outside the small flange that the utility model motor connecting flange uses
The structure of the additional reinforcing rib of cylinder, compared to the large flange outer barrel of conventional motor connecting flange, not only reduces motor connecting flange
Consumptive material, be more the increase in the intensity of motor connecting flange.
The utility model is simple in structure, reasonable design, is capable of the service life of effective prolonged deceleration machine, internal heat dissipating space
Greatly, be conducive to the heat dissipation of speed reducer.
