Abstract
The utility model discloses a planetary gear speed reducer which comprises a first stage planetary gear mechanism arranged at the input end. A sun gear in the first stage planetary gear mechanism is arranged on an input shaft of the planetary gear speed reducer, the input shaft of the planetary gear speed reducer is connected with an output shaft of a motor, the input shaft is supported by a one-way bearing, the one-way bearing is arranged in a bearing support, an electromagnetic brake is arranged on the outer side of the bearing support, and the electromagnetic brake is controlled by a switch of the motor to be opened and closed. According to the planetary gear speed reducer, the one-way bearing is arranged on the input shaft of the planetary gear speed reducer, and the bearing support of the one-way bearing is controlled by the switch of the motor to be braked. Due to the fact that a brake device is arranged in the speed reducer, the planetary gear speed reducer is simpler in structure and higher in reliability.
Description
Technical field
The utility model relates to reductor.
Background technology
On capstan winch, by planet-gear speed reducer, batch, guarantee that capstan winch can not reverse, in prior art, conventionally in motor, install brake additional.But this structure is complex structure not only, reliability is also not high enough.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of planet-gear speed reducer, and its brake structure is simple, and reliability is high.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of planet-gear speed reducer, this planet-gear speed reducer comprises the first order sun and planet gear that is positioned at input end, sun wheel in described first order sun and planet gear is installed on the input shaft of this planet-gear speed reducer, the input shaft of this planet-gear speed reducer connects with the output shaft of motor, described input shaft is supported by a unilateral bearing, described unilateral bearing is located in a bearing frame, the outside of described bearing frame is provided with an electromagnetic brake, described electromagnetic brake is controlled and is opened and closed by the switch of motor, when motor is switched on, electromagnetic brake departs from bearing frame, when motor no power and reversion, the locked bearing frame of electromagnetic brake.
As preferably, described bearing frame is square structure, described electromagnetic brake is upper and lower split type structure, and electromagnetic brake the first half and the latter half are equipped with the square draw-in groove that blocks described bearing frame, when motor is switched on, electromagnetic brake the first half and the latter half are separated and square draw-in groove departs from bearing frame, and when motor no power and reversion, electromagnetic brake the first half and the latter half closure and square draw-in groove block bearing frame.
As preferably, between the planetary wheel in described planet-gear speed reducer and pinion carrier, be provided with needle bearing.
As preferably, between the input shaft of described planet-gear speed reducer and the output shaft of motor, be provided with coupler.
The utility model arranges unilateral bearing on the input shaft of planet-gear speed reducer, and the bearing frame of this unilateral bearing is controlled brake by the switch of motor, and because brake gear is arranged in reductor, structure is simpler, and reliability is higher.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is unilateral bearing and electromagnetic brake fit structure schematic diagram.
The specific embodiment
With reference to figure 1 and Fig. 2, illustrate as a kind of planet-gear speed reducer of the utility model,
This planet-gear speed reducer 1 comprises the first order sun and planet gear that is positioned at input end, sun wheel in described first order sun and planet gear is installed on the input shaft 2 of this planet-gear speed reducer, the input shaft 2 of this planet-gear speed reducer 1 connects with the output shaft 4 of motor 3, described input shaft is supported by a unilateral bearing 5, described unilateral bearing is located in a bearing frame 6, the outside of described bearing frame is provided with an electromagnetic brake 7, described electromagnetic brake is controlled and is opened and closed by the switch of motor, when motor is switched on, electromagnetic brake 7 departs from bearing frame, the output shaft 4 of motor 3 drives the input shaft 2 of planet-gear speed reducer to rotate, thereby this planet-gear speed reducer normal operation, when motor no power and reversion, the locked bearing frame of electromagnetic brake 7, effect due to unilateral bearing, the input shaft 2 of this planet-gear speed reducer 1 can not rotate, thereby this planet-gear speed reducer is not worked.
Concrete, described bearing frame is square structure, described electromagnetic brake is upper and lower split type structure, and electromagnetic brake the first half and the latter half are equipped with the square draw-in groove that blocks described bearing frame, when motor is switched on, electromagnetic brake the first half and the latter half are separated and square draw-in groove departs from bearing frame, and when motor no power and reversion, electromagnetic brake the first half and the latter half closure and square draw-in groove block bearing frame.The fit structure of bearing frame and electromagnetic brake can be guaranteed the reliability of brake.
In addition, between the input shaft of described planet-gear speed reducer and the output shaft of motor, be provided with coupler.In described planetary reducer, between planetary wheel and pinion carrier, be provided with needle bearing, guarantee stability and the reliability of running.
