Abstract
The utility model relates to a lubricated leak protection speed reducer of bearing, including box, input shaft, bevel gear pair, output shaft, the perpendicular cross-under of input shaft is on the box, the input shaft from top to bottom in proper order cross-under center-aligning roller bearing, thrust ball bearing, down center-aligning roller bearing support on the box in the input bearing frame on the boss, be equipped with the skeleton oil blanket between the boss in input shaft and the input bearing frame. Adopt aligning roller bearing, thrust ball bearing, lower aligning roller bearing to support the input shaft to set up the skeleton oil blanket in the bottom of bearing and carry out leak protection oil seal, it is convenient to install, and the skeleton oil blanket is ensured by its spring to tighten up when wearing and tearing appear in long-term use, avoids wearing and tearing to cause the bearing oil leak, can effectively ensure bearing lubrication, safe handling.
Description
Technical Field
The utility model relates to a speed reducer, the lubricated leak protection speed reducer of bearing specifically says so.
Background
In the vertical input structure of traditional speed reducer, adopt O type circle sealed between the bearing supporting seat of input shaft and the input shaft, when installation O type circle, the installation accuracy is wayward, and uses easily wearing and tearing for a long time, has the oil leak hidden danger, and lubricating oil leaks in the bearing and influences normal, the safe handling of bearing and input shaft.
Disclosure of Invention
The utility model provides a simple structure, simple to operate is difficult for the lubricated leak protection speed reducer of bearing of oil leak.
The utility model adopts the technical proposal that: the utility model provides a lubricated leak protection speed reducer of bearing, includes box, input shaft, bevel gear pair, output shaft, the perpendicular cross-under of input shaft is on the box, its characterized in that: the input shaft is sequentially connected with the aligning roller bearing, the thrust ball bearing and the lower aligning roller bearing in a penetrating manner from top to bottom and supported on an inner boss of an input bearing seat on the box body, and a framework oil seal is arranged between the input shaft and the inner boss of the input bearing seat.
The lower centering roller bearing is connected with the input bearing seat through a screw in a penetrating manner and is locked and connected.
The utility model discloses a self-aligning roller bearing, thrust ball bearing, lower self-aligning roller bearing support the input shaft to set up the skeleton oil blanket in the bottom of bearing and carry out leak protection oil seal, it is convenient to install, and the skeleton oil blanket is ensured by its spring to tighten up when wearing and tearing appear in long-term use, avoids wearing and tearing to cause the bearing oil leak, can effectively ensure bearing lubrication, safe handling.
