Description
Technical Field
The utility model belongs to the technical field of the industrial air compressor machine, involve the oilless air compressor machine crankcase.
Background
The crankcase is the basic part of air compressor machine, supplies to place subassembly such as bent axle, connecting rod and other auxiliary assembly to through bolt fastening on the base. It bears not only the gas force and inertia force generated by the operation of the air compressor, but also the gravity of all the components on it.
Shown in fig. 1 is a crankcase having a bearing housing 1, bearing location holes 2 provided in the bearing housing, a support base 3 provided at the top of the bearing housing for connection to a cylinder, and a U-shaped open through hole 4 in the support base through which a connecting rod passes for connection to a piston in the cylinder. One end of the supporting seat is designed into an open structural design, so that the installation of a connecting rod and a crank is facilitated, but two separated fork plates extending from the front end of the supporting seat are easily stressed and thermally deformed, and further the sealing performance of the cylinder is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: provided is a crankcase having high strength and excellent sealing performance.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
an oilless air compressor crankcase comprises a bearing seat and a square supporting seat which are integrally cast; the bottom of the bearing seat is provided with a supporting leg, and a bearing mounting hole is formed in the bearing seat; the supporting seat is positioned at the top of the bearing seat, one side of the supporting seat is connected with the top of the bearing seat, a stud is arranged at the top of the supporting seat, a circular through hole is formed in the supporting seat, and a downward groove is formed in the edge of the circular through hole at the top of the supporting seat; the supporting seat bottom sets up the connection and is in the triangle reinforcing plate of bearing frame side.
The utility model has the advantages that: the original open U-shaped via hole in the supporting seat is modified into a closed circular through hole, and the triangular reinforcing plate is arranged at the bottom of the supporting seat, so that the strength of the supporting seat is improved, the stress and the thermal deformation of the supporting seat are avoided, and the sealing performance of the cylinder is ensured.

FIG. 1 is a block diagram of a prior art crankcase;
FIG. 2 is a block diagram of a crankcase in an embodiment;
FIG. 3 is a side view of a crankcase in an embodiment;
fig. 4 is a structural view of a double pump head in the embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
The crankcase shown in fig. 2 and 3, which is used in an oilless air compressor, includes a bearing housing 10 and a square support base 20, which are integrally cast. The bottom of the bearing seat 10 is provided with a supporting leg, a bearing mounting hole 11 is arranged in the bearing seat 10, a bearing with a corresponding model is mounted in the bearing mounting hole 11, and an output shaft of the motor penetrates through the bearing to be connected with the fan blade. The support seat 20 is located at the top of the bearing seat 10, one side of the support seat is connected with the top of the bearing seat 10, a stud 30 is arranged at the top of the support seat 20, and a bolt in the air cylinder is screwed in the stud to realize fixation. A circular through hole 40 is formed in the supporting seat 20, a downward groove 50 is formed in the edge of the circular through hole in the top of the supporting seat 20, and a connecting rod connected with an output shaft of the motor penetrates through the circular through hole to be connected with a piston in the cylinder. The supporting seat 20 has a reinforcing edge 60 with a certain thickness around the circular through hole, and the reinforcing edge uniformly bears the gas force and the inertia force generated by the operation of the air compressor and the gravity of the air cylinder. And a triangular reinforcing plate 70 connected to the side surface of the bearing seat 10 is arranged at the bottom of the supporting seat 20 to support the supporting seat 20, so that the strength of the supporting seat 20 extending outside the bearing seat 10 is further improved, and the strength of the crankcase is further improved.
Above-mentioned crankcase revises into confined circular through-hole original open-ended U type via hole in with the supporting seat to set up the triangle reinforcing plate in the bottom of supporting seat, improved the intensity of supporting seat, avoided the atress of supporting seat, be heated deformation, guaranteed the sealing performance of cylinder.
Fig. 4 shows a double pump head of an air compressor, which includes a motor a, a fan blade B, a crankcase C and a cylinder D, wherein both sides of the motor are provided with the crankcase and the fan blade, and the two crankcases are connected in a limiting manner by a connecting rod E. A bearing is arranged in a bearing mounting hole 11 of the crankcase, and an output shaft of the motor penetrates through the bearing to be connected with the fan blades. The triangular reinforcing plate is provided with screw holes 71, and a housing for covering the fan blades is locked into the screw holes by screws to realize fixation.
The top of the supporting seat 20 is provided with a supporting plate 80 corresponding to the triangular reinforcing plate, and two ends of the supporting plate are respectively connected with two adjacent studs. The backup pad is used for supporting the cylinder, has avoided all gravity of cylinder to all exert on the double-screw bolt, has further improved the intensity of crankcase.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
