Abstract
The utility model provides a gear reducer which has small volume, low noise, and high transmission efficiency and saves cost. The gear reducer comprises a box body, an end cover, an input shaft, an intermediate shaft, an output shaft, a primary driving gear, a primary driven gear, a secondary driving gear and a secondary driven gear, wherein the input shaft, the intermediate shaft and the output shaft are positioned in the box body; the primary driving gear is arranged on the output shaft; the primary driven gear and the secondary driving gear are arranged on the intermediate shaft; the secondary driven gear is arranged on the output shaft; through covers are arranged on the box body and at two ends of the input shaft, the intermediate shaft and the output shaft; shock absorbers are arranged between the input shaft and the through cover as well as between the output shaft and the through cover; the modulus of the primary driving gear and the primary driven gear is 1.5; and the modulus of the secondary driving gear and the secondary driven gear is 3. The driving gears adopt small modulus, so the volume of the equipment is small, the manufacturing precision is high and the transmission efficiency is improved. The shock absorbers are arranged on the input shaft and the output shaft, so the noise is reduced, the service life is long and the cost is saved.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of gear reduction unit.
Background technique
Existing gear reduction unit, gear diameter reaches, and relatively heavier, noise is big in the working procedure, and the power that equipment operation needs is big, and device load-bearing capability is low, and contact strength of tooth surface is weak, is prone to lose efficacy, and the life-span is low.
The model utility content
The purpose of the utility model provides that a kind of volume is little, noise is low, and transmission efficiency is high, practices thrift the gear reduction unit of cost.
Realize the gear reduction unit of the utility model purpose; Comprise casing and end cap; Be positioned at input shaft, jack shaft and the output shaft of said casing; Be installed in the one-level driving gear of said input shaft, be installed in the one-level driven gear and the secondary driving gear of said jack shaft, be installed in the secondary driven gear of said output shaft; The two ends of said output shaft, jack shaft and input shaft are provided with the logical lid that is installed on the said casing; Be provided with vibration damper between said input shaft and output shaft and the logical lid; The modulus of said one-level driving gear and one-level driven gear is 1.5, and the modulus of said secondary driving gear and secondary driven gear is 3.
The beneficial effect of the utility model is following:
The gear reduction unit of the utility model because driving gear adopts little modulus, makes that the volume of equipment is little, makes the precision height, and transmission efficiency improves; Because on input shaft and output shaft, be provided with vibration damper, so noise reduces, reliable operation, the life-span is long, practices thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model gear reduction unit.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1; The gear reduction unit of the utility model; Comprise casing 5 and end cap 1, be positioned at input shaft 8, jack shaft 12 and the output shaft 3 of said casing 5, be installed in the one-level driving gear 10 of said input shaft 8; Be installed in the one-level driven gear 11 and secondary driving gear 13 of said jack shaft 12, be installed in the secondary driven gear 2 of said output shaft 3; The two ends of said output shaft 3, jack shaft 12 and input shaft 8 are provided with the logical lid 4 that is installed on the said casing 5; Said input shaft 8 and output shaft 3 and logical be provided with vibration damper 6 between covering 4; The modulus of said one-level driving gear 10 and one-level driven gear 11 is 1.5, and the modulus of said secondary driving gear 13 and secondary driven gear 2 is 3.
The gear reduction unit of the utility model because driving gear adopts little modulus, makes that the volume of equipment is little, makes the precision height, and transmission efficiency improves; Because on input shaft 8 and output shaft 3, be provided with vibration damper 6, so noise reduces, reliable operation, the life-span is long, practices thrift cost.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in related domain make the utility model technological scheme all should fall in the protection domain that claims of the utility model confirm.
