Abstract

The utility model relates to a gear supporting structure, in particular relates to a novel gear supporting structure and belongs to the field of machinery. The novel gear supporting structure comprises a bearing, a shaft, a gear and a spring collar, wherein the shaft is arranged on a rack and is in interference fit with the rack; the shaft and the rack are fixed and locked through a taper pin to form a whole body, and the shaft does not rotate. A conventional two-bearing structure is replaced by a self-aligning roller bearing, so that the cost is reduced; meanwhile, the self-aligning roller bearing has a self-aligning function, so that the contact performance of the gear is improved, and the service life of the gear is prolonged; the bearing is locked through the taper pin to prevent the shaft from rotation and axial movement, so that the stability of a system is improved; the rack is compact and simple in structure, the number of processing parts is small, and the manufacturing cost is greatly reduced.

Description

A kind of supporting structure of new gear

Technical field

The utility model relates to a kind of supporting structure of gear, is specifically the gear supporting structure that relates to a kind of compact structure, belongs to mechanical field.

Background technique

The gear supporting structure of generally using at present, its gear is connected on axle by key, gear both sides distribution cone roller bearing, tapered roller bearing is fixedly mounted in frame by spacer and end cap, its bearing inner race is connected with axle interference, and bearing and axle rotate jointly, requires its machining accuracy high, and gear both sides distribution cone roller bearing, bearing is connected with frame, and frame framework is complicated, and processing accessories number is large, installing space is large, makes production product cost high.

Summary of the invention

The object of the invention is to provide a kind of supporting structure that adopts the gear that frame and axle be fixed as one.

To achieve these goals, the technological scheme that the utility model adopts is a kind of supporting structure of new gear, and it comprises: bearing, axle, gear and check ring; Axle is arranged in frame, adopts interference fit, and fix by taper pin between axle and frame, locks, and axle and frame become one, and axle does not rotate; Described bearing is arranged in bore, and bearing outer ring and gear adopt interference fit, and bearing inner race coordinates with shaft clearance, and fixes by check ring.

Described bearing is selfaligning roller bearing, take bearing inner race as support.

The utility model has the advantage of: selfaligning roller bearing of Selection of Bearings substitutes the structure of existing two bearings, and it has reduced cost, bearing has aligning effect simultaneously, improves the contact performance of gear, the working life of having improved gear; Bearing is locked by taper pin, prevents axle rotation, and moves axially, and has improved the stability of system; Rack construction is compact simple, and processing accessories number is few, and manufacture cost significantly reduces.
