Description

Reducer structure

Technical field

The utility model relates to a kind of reducer structure.

Background technique

General motor is when using, about its rotating speed Chang Gaoda 3000 (RPM), very inconvenience in practical application, so on using, often adopt the high rotating speed that one speed reducer lowers motor, so that actual application, retarder is except that reducing rotating speed, and secondly a function more can reach the characteristics of high torsion, to reach the effect of drive, so often be applied to intermediary's assembly of a driving device interlock.

Commonly use retarder 1 as shown in Figure 1, this retarder 1 is to adopt plurality of fixed post 12 to fix it to commonly use retarder 1, and main gear 13 structures are placed 12 on plurality of fixed post, but its fixing column 12 uses a kind of mode of riveted up and down that internal gear 13 is covered on wherein, if during internal gear 13 faults, then the whole retarder 1 of commonly using need be replaced it, non-only inconvenience, more cause the cost waste, economic benefit deficiency, and when commonly using retarder 1 and inserting its shell, more the Percent of contact area deficiency of Chang Yin and shell, cause and become flexible and rock, more can produce error during action, cause the precision deficiency, and gear 13 needs with lubricant oil when rotating auxiliary to reduce wear, but fail at the design of waterproof or anti-wet goods function because of the design of commonly using retarder 1, cause lubricant oil often to leak outside and ooze.

Summary of the invention

The purpose of this utility model provides a kind of reducer structure, has fast assembling-disassembling, characteristics easy to maintenance.

Above-mentioned purpose of the present utility model is to realize like this, a kind of reducer structure, it is characterized in that comprising: a loam cake, a hole and some grooves have been installed, be provided with waterproof washer in the hole, waterproof washer combines with waterproof ring, and an inner axle center stretches through out from hole, its some grooves for ball bearings fixedly the axle center in wherein; One lower cover is provided with some grooves, fixing plurality of balls bearing, some axle center are fixed in the groove by ball bearing, and in being provided with an O type ring with the loam cake junction point, by this O type ring with the upper and lower cover involution; Some axle center combine with different gears, and are fixed between upper and lower cover by ball bearing; Plurality of gears is coupled between its gear.

Because the utility model has installed waterproof washer and O type ring, can promote the popularity of using scope with the characteristics of its water proof and dust proof; In addition, utilize the position, hole between ball bearing and shell to fix, the complete mat of the gear axle center of the utility model inside is fixed in the position, hole, and promote its precision, ball bearing more has the characteristics that reduce noise, fast quick-detach, make the utility model only change wheel can reach and change its gear ratio and reduce noise.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.
