Abstract

The utility model provides a planetary speed reducer. A rotating input wheel (3) is arranged on a wheel arm to simultaneously form a casing of a speed reducer; a central wheel is a profile shifted gear set with differential teeth. The utility model overcomes the defect that the planetary speed reducer in the prior art needs to have a separated casing, and has large volume, complicated structure and high cost due to the adoption of internal-engaging central wheel. The utility model has the advantages of strong transmission rigidity, high efficiency and the irreversibility of transmission.

Description

Planetary reducer
The utility model relates to a kind of planetary reducer.
Planetary reducer is the same with other retarders traditionally its shell, and links to each other with working machine with machine tool by other driving mechanisms, and how with two central gears of interior external tooth and planet wheel engagement, so the planetary reducer volume is bigger, complex structure, and cost is higher.
The purpose of this utility model will provide a kind of exactly can overcome above defective, and volume is little, simple in structure, the planetary reducer that cost is lower.
The planetary reducer that the utility model provides, have planet wheel, pivoted arm and central gear, have on the pivoted arm one with the pivoted arm central axis in the axle the rotation wheel for inputting, and this rotation wheel for inputting and reducer shell are integrated, central gear is a pair of poor tooth modified gear group, wherein one another is that transmitting gear is installed on the rotary output axis for fixed gear is installed on the support, rotate wheel for inputting with Bearing Installation on rotary output axis.
When planet wheel was done revolution with the rotation wheel for inputting according to the central axis rotation, its was also meshing rotation with central gear simultaneously, rotates the shared angle of tooth difference tooth thereby promote transmitting gear relative fixed gear after public affairs are circled.Owing to adopting difference tooth modified gear group as central gear, the relation of the rotating speed of the rotating speed of rotary output axis and rotation wheel for inputting is only relevant with the poor number of teeth of difference tooth modified gear group with the number of teeth of transmitting gear, i.e. velocity ratio=transmitting gear the number of teeth/difference number of teeth.
The planetary reducer that the utility model provides, its housing has the member function of pivoted arm and belt pulley concurrently, be central gear to differ from tooth modified gear group simultaneously, this than the volume-diminished of the planetary reducer that prior art provided of identical speed ratio many, reduce material, do not had interior grinding tooth wheel, then simplified processing technology, simplify the structure, cost is descended.This structure also makes transmission rigidity stronger, and efficient is higher and have a nonreversibility of transmission.
Fig. 1 is an A-A diagrammatic sectional view of the present utility model
Fig. 2 is the left view that Fig. 1 removes wheel cap
Planetary reduction gear provided by the utility model is installed a gear for rotating at rotary output axis 1 Gear 5, have one with the same basic circle external diameter of this transmitting gear, and to grind that established law cuts into and transmitting gear The gear that the number of teeth differs 1~3 tooth is fixed gear 2, and fixed gear is fixed on the support. Transmitting gear and solid Fixed gear is arranged in juxtaposition, and planetary gear 4 meshes simultaneously with transmitting gear and fixed gear.
Planetary gear is installed in one with axle and rotates in the wheel for inputting 3, and this rotates wheel for inputting is turning gear simultaneously The housing of the planetary reducer that the centre wheel that wheel and fixed gear form and planetary gear consist of. Rotate defeated Entering wheel is installed on the rotary output axis with bearing. When rotating the wheel for inputting rotation, planetary gear is just according to the pivoted arm axis Revolution, rotation is done in simultaneously planetary gear and centre wheel engagement, and when public affairs circled, transmitting gear was just relatively fixing Gear rotates the shared angle of tooth difference tooth.
Planetary reduction gear provided by the utility model, tooth difference are 1~3 tooth, and planetary gear uses 1~3. When being used for the little speed ratio of the big modulus of the appropriate to the occasion employing of transmitted power, with 2~3 planetary gears, rotate when being used for transmitting The time, should adopt little modulus, with a planetary gear.
Planetary reduction gear provided by the utility model has a wheel cap 6 to be installed in to rotate that wheel for inputting consists of Form the reducer shell of sealing on the reducer shell.
Embodiment: as shown in Figure 1, 2, be applied to the small plastic extruder.Rotating wheel for inputting 3 is belt pulleys, and planetary pinion 4 is 7 teeth, and in belt pulley, fixed gear 2 is 27 teeth to its axle with Bearing Installation, and transmitting gear 5 is 30 teeth, uses 3 planetary pinions 4, and the formed housing of belt pulley is with wheel cap 6 sealings, interior notes oil lubricating.

Claims (3)

1. planetary reducer, have planetary pinion, pivoted arm and central gear, it is characterized in that having on the pivoted arm rotation wheel for inputting coaxial with the pivoted arm central axis, and this rotation wheel for inputting and reducer shell are integrated, central gear is a pair of poor tooth modified gear group, and wherein one is fixed gear, is installed on the support, another is that transmitting gear is installed on the rotary output axis, rotate wheel for inputting with Bearing Installation at rotary output axis.
2. planetary reducer as claimed in claim 1 is characterized in that fixed gear and the turning gear gear teeth difference as central gear is 1~3 tooth, and planetary pinion uses 1~3.
3. planetary reducer as claimed in claim 1 or 2 is characterized in that having a wheel cap to be installed in to form the reducer shell of sealing on the reducer shell that rotates the wheel for inputting formation.
